Learn how to connect your Insignia soundbar to any TV using HDMI ARC, optical, Bluetooth, or analog connections. Step-by-step instructions, troubleshooting tips, and TV-brand settings included.
Your Insignia soundbar is sitting there, still in the box or maybe already unboxed and looking lonely next to your TV. The manual might as well be written in hieroglyphics, and you just want sound coming out of this thing already.
Good news: connecting an Insignia soundbar to your TV takes about 5-10 minutes with the right method. After setting up dozens of these soundbars across different TV brands, I've figured out what works, what doesn't, and why that PCM setting everyone mentions actually matters.
This guide covers every connection method available - HDMI ARC, optical, Bluetooth, and analog - plus the TV-specific settings for Samsung, LG, Roku TV, and Fire TV that most guides skip over. Whether you're dealing with an NS-HTSB22 or an older NS-HSB318, you'll find exactly what you need here.
Not sure which connection method to use? Here's your decision made simple.
Best Connection Methods (Ranked by Quality):
HDMI ARC – Best audio quality, TV remote controls volume, single cable
Optical (TOSLINK) – Excellent digital audio, widely compatible
Bluetooth – Wireless convenience, slight audio delay possible
Analog (AUX/RCA) – Last resort for older TVs without digital outputs
The right choice depends on what ports your TV and soundbar actually have. Check the back of both devices before committing to a method.
Quick Decision Flowchart:
Does your TV have an HDMI port labeled "ARC"? If yes, and your Insignia soundbar has HDMI ARC (models like NS-HTSB22 and NS-HTSB2123), use HDMI ARC. If your TV lacks HDMI ARC or your soundbar is an NS-HSB318 (which has no HDMI), go with optical.
Bluetooth works when you want zero cables, but expect a slight audio delay that makes it less ideal for movies with lots of dialogue. The analog AUX connection? Reserve that for situations where nothing else is available.
Connection | Audio Quality | TV Remote Control | Cable Needed | Best For |
|---|---|---|---|---|
HDMI ARC | Excellent | Yes | HDMI (not included) | Most modern setups |
Optical | Very Good | No | Optical (included) | Universal compatibility |
Bluetooth | Good | No | None | Wireless convenience |
Analog | Basic | No | 3.5mm (included) | Older TVs only |
If you've already connected your soundbar but hear nothing, jump to the troubleshooting section to fix insignia tv no audio issues first - there's a quick solution that works about 70% of the time.
Before touching any cables, gather everything you'll need. Nothing kills momentum like realizing you're missing a crucial cable halfway through setup.
What's Included with Your Insignia Soundbar:
The NS-HTSB22 and similar models ship with an optical cable, a 3.5mm AUX cable, the remote control (check for batteries), and the power adapter. Wall mounting hardware is also included if you plan to mount the soundbar.
Here's what trips up most people: HDMI cables are NOT included. If you want to use HDMI ARC (and you should, it's the best option), you'll need to buy an HDMI cable separately.
HDMI Cable Requirements:
Not just any HDMI cable will work for ARC. You need HDMI 1.4 or newer, which is labeled as "High Speed HDMI" on the packaging. Standard HDMI cables from 2009 or earlier won't support the Audio Return Channel feature. When in doubt, grab a High Speed HDMI cable with Ethernet - they're inexpensive and guaranteed to work.
Pre-Setup Checklist:
[ ] Insignia soundbar unpacked with protective films removed
[ ] Remote control with two AAA batteries installed
[ ] Power adapter connected and outlet accessible
[ ] Optical cable (included) or HDMI cable (must purchase)
[ ] TV remote nearby for settings changes
[ ] Clear view of ports on both TV and soundbar
Model-Specific Notes:
The NS-HSB318 does NOT have HDMI connectivity at all - only optical, AUX, and Bluetooth. If you have this model, skip the HDMI ARC section entirely and head to optical or Bluetooth.
The NS-HTSB2123 (2.1 system with wireless subwoofer) includes all standard connections plus a dedicated subwoofer output. The subwoofer pairs automatically when you plug it in.
Finding the right ports sounds simple until you're staring at a wall of identical-looking HDMI ports on your TV. Here's how to identify exactly what you need.
Insignia Soundbar Back Panel (NS-HTSB22):
Looking at the back of the NS-HTSB22 from left to right, you'll typically find: the power input, USB port (for playing MP3 files, not for audio connection), HDMI ARC port, Optical input, and AUX IN (3.5mm jack).
The USB port confuses people constantly - it's for playing music files directly from a flash drive, not for connecting to your TV. Don't waste time trying to make that work for TV audio.
Which Ports Does Your Model Have?
Model | HDMI ARC | Optical | AUX | Bluetooth | USB |
|---|---|---|---|---|---|
NS-HTSB22 | ✓ | ✓ | ✓ | ✓ | ✓ |
NS-HSB318 | ✗ | ✓ | ✓ | ✓ | ✗ |
NS-HTSB2123 | ✓ | ✓ | ✓ | ✓ | ✓ |
NS-SB216 | ✗ | ✓ | ✓ | ✓ | ✗ |
Finding the ARC Port on Your TV:
This is crucial. HDMI ARC only works through a specific HDMI port on your TV - not just any HDMI input.
Look at the back or side of your TV where the HDMI ports are located. One of them should be labeled "HDMI (ARC)" or "HDMI 2 ARC" or sometimes "TV-ARC." The label might be tiny, so grab a flashlight if needed.
On most TVs manufactured after 2015, HDMI 1 or HDMI 2 is typically the ARC port. Some newer TVs have eARC (enhanced Audio Return Channel) which is backward compatible with regular ARC.
If none of your HDMI ports show an ARC label, your TV may not support HDMI ARC at all. In that case, use optical instead.
Finding the Optical Port on Your TV:
The optical port (also called TOSLINK or Digital Audio Out) is a small square port with a hinged dust cover. It's usually found near the HDMI ports on the back panel. Some TVs have it on the side.
Pull off the protective cap to reveal the port. The optical cable connector only fits one way - don't force it.
If you're having trouble finding the right input source on your TV altogether, you may need to fix Insignia TV input problem before proceeding with soundbar setup.
HDMI ARC delivers the best audio quality and lets you control the soundbar volume with your TV remote. It's the recommended setup for anyone whose equipment supports it.
What You Need:
HDMI cable (not included - must purchase separately)
TV with HDMI ARC port
Insignia soundbar with HDMI ARC (NS-HTSB22, NS-HTSB2123)
Step-by-Step HDMI ARC Setup:
Power off both devices. Unplug the TV and soundbar from the wall. This prevents potential handshake issues during initial setup.
Locate the HDMI ARC port on your TV. Look for the port labeled "ARC" or "HDMI (ARC)." This is usually HDMI 1, HDMI 2, or HDMI 3 depending on your TV model.
Locate the HDMI ARC port on your soundbar. On the NS-HTSB22, it's on the back panel, clearly labeled "HDMI ARC."
Connect the HDMI cable. Plug one end into the TV's HDMI ARC port and the other end into the soundbar's HDMI ARC port. Make sure both connections click in firmly.
Plug in and power on the TV first. Wait for it to fully boot up before turning on the soundbar.
Power on the soundbar. Press the power button on the soundbar or remote.
Select HDMI/ARC input on the soundbar. Press the Source button on the soundbar or remote repeatedly until the LED indicator turns white. White means ARC mode is active.
Enable HDMI CEC on your TV. Navigate to your TV's settings menu. This setting has different names depending on your TV brand - we'll cover specific paths in the TV-Brand Settings section. Generally, look for Settings → System → HDMI CEC or Settings → General → External Device Manager.
Set TV audio output to external speakers. In your TV's audio settings, change the output from "TV Speakers" to "Receiver," "External Speakers," "HDMI ARC," or "Audio System."
Test the connection. Play something on your TV. Audio should come through the soundbar. Try adjusting volume with your TV remote - if CEC is working correctly, the soundbar volume should respond.
PCM Audio Format Setting (Critical):
Many Insignia soundbars require your TV's digital audio output set to PCM format. If you're getting no sound or only static, navigate to your TV's audio settings and change "Digital Audio Output" or "Audio Format" from "Auto" or "Dolby Digital" to "PCM."
This is the single most common fix for Insignia soundbar audio issues. The soundbar's internal processing handles PCM better than bitstream formats.
LED Indicator Reference:
White (solid) = HDMI ARC mode active
White (blinking) = Searching for ARC connection
If setup is successful but you're experiencing timing issues between video and audio, check out how to fix insignia audio sync problems in the dedicated troubleshooting section below.
Common HDMI ARC Mistakes:
Using a non-ARC HDMI port is the number one error. The soundbar will power on and show the white LED, but no audio will pass through because standard HDMI ports don't return audio to external devices.
Not enabling CEC is mistake number two. Without CEC (HDMI-CEC, Anynet+, SIMPLINK, or whatever your TV calls it), the TV doesn't know to send audio through that port.
The optical connection (also called TOSLINK or digital optical) provides excellent audio quality and works with virtually any TV made in the last 15 years. It's your best alternative when HDMI ARC isn't available or isn't cooperating.
When to Use Optical:
Your TV doesn't have HDMI ARC
Your Insignia soundbar model has no HDMI (NS-HSB318, NS-SB216)
HDMI ARC setup failed and you need a reliable backup
You're connecting to an older audio source like a DVD player
What You Need:
Optical cable (included with most Insignia soundbars)
TV with optical audio output port
Step-by-Step Optical Setup:
Remove the protective caps from both ends of the optical cable. These small plastic or rubber caps protect the fiber optic ends during shipping. Save them in case you need to store the cable later.
Locate the optical output on your TV. It's a small square port, usually labeled "Optical," "Digital Audio Out," "TOSLINK," or "SPDIF."
Locate the optical input on your soundbar. On Insignia models, it's labeled "OPTICAL" on the back panel.
Connect the optical cable. The connector only fits one way. Press firmly until you feel it click into place. A loose connection causes intermittent audio or crackling sounds.
Change your TV's digital audio output to PCM. This step is critical. Navigate to your TV's audio settings and look for "Digital Audio Output Format," "Audio Format," or "SPDIF Output." Change it from "Auto," "Bitstream," or "Dolby Digital" to "PCM."
Select optical input on the soundbar. Press the Source button repeatedly until the LED indicator turns green. Green means optical mode is active.
Test audio playback. Play content on your TV and verify sound comes through the soundbar.
Why PCM Matters (Technical Explanation):
Here's what's actually happening: Your TV receives audio in various formats - Dolby Digital, DTS, PCM, etc. When set to "Auto" or "Bitstream," your TV passes these formats unchanged to the soundbar.
The problem? Many Insignia soundbars cannot decode Dolby Digital or DTS internally. They need the TV to decode the audio first and send it as PCM (Pulse-Code Modulation), which is basically raw, uncompressed digital audio that any soundbar can play.
When the soundbar receives a format it can't decode, you get silence, static, or strange popping sounds. Setting the TV to PCM output solves this by making the TV do the audio decoding work.
PCM Settings by TV Brand (Quick Reference):
Samsung: Sound → Expert Settings → Audio Format → PCM
LG: Sound → Sound Out → Optical → PCM
Roku TV: Settings → Audio → Digital Audio Format → PCM
Fire TV: Settings → Display & Sounds → Audio → Digital Audio Format → PCM
For complete navigation paths, see the TV-Brand Settings section below.
LED Indicator for Optical:
Green (solid) = Optical mode active
Green (blinking) = Waiting for optical signal
Optical Troubleshooting:
If you hear crackling or static through the optical connection, the cable likely isn't fully seated. Unplug it and reconnect, pressing until it clicks.
If there's no sound at all, double-check that your TV's audio output is set to "External Speakers" or "Audio System" rather than "TV Speakers." Some TVs won't send audio through optical until you explicitly tell them to.
If you're still having audio issues with your Insignia TV specifically, you might need to adjust insignia sound settings through the TV's built-in menus.
Bluetooth offers the ultimate convenience - no cables, no ports to worry about. It's ideal for streaming music from your phone and works reasonably well for casual TV watching.
Honest Limitations:
Bluetooth introduces a small audio delay (typically 40-200 milliseconds depending on the codec). For music listening, this is imperceptible. For dialogue-heavy movies or gaming, you might notice voices don't quite sync with lip movements.
Bluetooth also compresses audio, so audiophiles will notice lower quality compared to wired connections. For most people watching Netflix on a Tuesday night, though? It sounds perfectly fine.
When Bluetooth Makes Sense:
Minimal cable clutter is your priority
You're primarily streaming music
Your TV has Bluetooth audio output
You're setting up a temporary arrangement
Bluetooth Pairing Steps:
Turn on the soundbar. Press the power button.
Enter Bluetooth pairing mode. Press the Source button repeatedly until the LED indicator blinks blue. The blinking indicates the soundbar is discoverable and ready to pair.
On your TV, navigate to Bluetooth settings. The exact path varies by TV brand, but generally: Settings → Bluetooth → Add Device or Settings → Remote & Devices → Bluetooth.
Scan for devices. Your TV should find "NS-HTSB22" (or your specific model name) in the list of available devices.
Select the soundbar to pair. Click on the soundbar name in the device list.
Enter PIN code if prompted. The default PIN for Insignia soundbars is 0000 (four zeros).
Wait for pairing confirmation. The LED on the soundbar will turn solid blue when successfully connected.
LED Indicator for Bluetooth:
Blue (blinking) = Pairing mode, waiting for connection
Blue (solid) = Bluetooth connected and active
Bluetooth Device Memory:
Your Insignia soundbar remembers the last connected device. Next time you turn on the soundbar and select Bluetooth mode, it will automatically reconnect to that device if it's in range.
To connect to a different device, you'll need to either disconnect the current device first or put the soundbar back into pairing mode by holding the Bluetooth/Source button.
Connecting Phones and Tablets:
The same pairing process works for smartphones and tablets. Put the soundbar in Bluetooth pairing mode (blinking blue), then search for Bluetooth devices on your phone. Select "NS-HTSB22" and enter 0000 if prompted.
This turns your Insignia soundbar into a Bluetooth speaker for music streaming when you're not watching TV.
If you're also trying to connect your phone to an Insignia TV for other purposes, the process to pair phone with insignia tv is similar but handled through the TV's Bluetooth menu instead.
Analog connections are your last resort when digital options aren't available. They work, but you'll get stereo sound only - no surround sound, no remote integration, and noticeably lower audio quality than digital connections.
When Analog is Necessary:
Your TV has no HDMI ARC and no optical output
You're connecting to legacy equipment (VCR, old cable box)
All digital ports are already in use
You need a quick temporary setup
What You Need:
3.5mm AUX cable (included with most Insignia soundbars)
TV with headphone jack or AUX output
3.5mm AUX Connection Steps:
Locate the audio output on your TV. This might be labeled "Headphone," "Audio Out," or "AUX Out." It's a small round jack, same size as a standard headphone plug.
Locate AUX IN on the soundbar. On Insignia models, it's a 3.5mm jack on the back panel.
Connect the 3.5mm cable. Plug one end into the TV's audio output and the other into the soundbar's AUX IN.
Select AUX input on the soundbar. Press Source repeatedly until the LED turns orange. Orange indicates AUX mode.
Adjust volume levels. Here's the tricky part with analog: set your TV volume to about 50-60%. Then control your main listening volume using the soundbar's remote. If you set TV volume too low, the soundbar won't receive enough signal. Too high, and you risk distortion.
LED Indicator for AUX:
Orange (solid) = AUX mode active
RCA Connection (Alternative):
If your TV has red and white RCA audio outputs instead of a 3.5mm jack, you'll need an RCA to 3.5mm adapter cable. Connect the red and white RCA plugs to your TV's audio output jacks, and the 3.5mm end goes into the soundbar's AUX IN.
RCA cables transmit the same analog stereo signal as the 3.5mm connection - there's no quality difference between the two methods.
Analog Limitations:
You won't get TV remote volume control with analog connections. The TV remote adjusts the TV's output level, but you'll need to use the soundbar remote for primary volume adjustments.
Sound quality is noticeably inferior to digital connections. If this is your only option and you're finding the volume inadequate, check our guide on how to fix insignia tv low volume to maximize output before it reaches the soundbar.
Generic instructions like "go to audio settings" don't help when you're staring at your TV's menu and can't find the right option. Here are the exact paths for major TV brands.
For HDMI ARC Setup:
Press Home on your Samsung remote
Navigate to Settings → Sound → Sound Output
Select "Receiver (HDMI)" or "HDMI ARC"
Go back to Settings → General → External Device Manager
Enable "Anynet+ (HDMI-CEC)"
For Optical Setup / PCM Setting:
Press Home on your Samsung remote
Navigate to Settings → Sound → Expert Settings
Select "Digital Output Audio Format"
Change to "PCM"
Additional Samsung Notes:
Samsung calls HDMI-CEC "Anynet+." If volume control isn't working through your TV remote, Anynet+ isn't enabled. Some Samsung models also have a "Sound Output" quick toggle in the notification panel - press and hold the volume button on the remote to access it.
For HDMI ARC Setup:
Press Settings on your LG remote
Navigate to Sound → Sound Out
Select "HDMI ARC" or "Use Wired Speaker"
Go to Settings → General → SIMPLINK (HDMI-CEC)
Turn SIMPLINK ON
Enable "Auto Power Sync" if available
For Optical Setup / PCM Setting:
Press Settings on your LG remote
Navigate to Sound → Sound Out
Select "Audio Out (Optical/HDMI ARC)"
Go to Sound → Additional Settings
Set "Digital Sound Out" to "PCM"
Additional LG Notes:
LG calls HDMI-CEC "SIMPLINK." If your soundbar isn't powering on automatically with the TV, check that Auto Power Sync is enabled within the SIMPLINK menu. If the external audio system isn't working after following these steps, changing the audio format to PCM often resolves the issue.
For HDMI ARC Setup:
Press Home on your Roku remote
Navigate to Settings → Audio
Set "Audio Mode" to "Auto"
Set "S/PDIF and ARC" to "Auto" or "PCM-Stereo"
Navigate to Settings → System → Control other devices (CEC)
Enable "System audio control"
For Optical Setup / PCM Setting:
Press Home on your Roku remote
Navigate to Settings → Audio
Select "S/PDIF and ARC"
Choose "PCM-Stereo"
For Insignia Roku TVs Specifically:
Insignia Fire TV and Roku TV models sometimes hide the PCM option in unexpected places. If you can't find it under Audio, try: Settings → Display & Sounds → Audio Output → Digital Audio Format.
While you're in settings, you might also want to configure insignia picture quality for the best overall viewing experience.
For HDMI ARC Setup:
Navigate to Settings → Display & Sounds
Select "Audio"
Enable "HDMI CEC Device Control"
Set "Surround Sound" to "Auto" or "Best Available"
For Optical Setup / PCM Setting:
Navigate to Settings → Display & Sounds
Select "Audio"
Set "Digital Audio Format" to "PCM"
Fire TV Quirk:
Fire TV's PCM option sometimes doesn't appear if you have a soundbar already connected via HDMI ARC. Disconnect the soundbar, change the setting to PCM, then reconnect.
For HDMI ARC Setup:
Press Menu on your Vizio remote
Navigate to Audio → TV Speakers
Turn TV Speakers OFF
Go to Audio → Digital Audio Out
Select "Auto" or "PCM"
For Optical Setup / PCM Setting:
Press Menu on your Vizio remote
Navigate to Audio → Digital Audio Out
Change to "PCM"
For HDMI ARC Setup:
Press Home on your Sony remote
Navigate to Settings → Display & Sound → Audio Output
Set "Speakers" to "Audio System"
Go to Settings → Channels & Inputs → External Inputs → BRAVIA Sync Settings
Enable "BRAVIA Sync Control"
For Optical Setup / PCM Setting:
Press Home on your Sony remote
Navigate to Settings → Display & Sound → Audio Output
Set "Digital Audio Out" to "PCM"
The soundbar is connected, the LED shows the right color, but nothing comes out. This is the most common problem, and in about 70% of cases, one simple fix resolves it.
The Fix That Works Most Often:
Change your TV's digital audio output format to PCM. Seriously, this is it. Most Insignia soundbars cannot decode Dolby Digital or DTS bitstream audio. When they receive these formats, they output silence instead of an error message.
Navigate to your TV's audio settings, find "Digital Audio Output," "Audio Format," or "SPDIF Output," and change it from "Auto" or "Dolby Digital" to "PCM."
Systematic Troubleshooting Checklist:
If PCM doesn't solve it, work through these checks in order:
Check 1: Power Verification
Is the soundbar actually on? The LED indicator should be lit. If there's no light at all, try a different power outlet. Check that the power cable is firmly connected at both ends.
Check 2: Input Source Selection
The soundbar must be on the correct input for your connection type. Press the Source button and watch the LED color:
White = HDMI ARC
Green = Optical
Blue = Bluetooth
Orange = AUX
Purple = USB
If you connected via optical but the soundbar shows white (HDMI mode), you won't hear anything.
Check 3: TV Audio Output Settings
Your TV might still be outputting audio through its internal speakers. Navigate to your TV's audio settings and look for "Sound Output," "Speakers," or "Audio Output." Change it from "TV Speakers" to "External Speakers," "Receiver," "HDMI ARC," or "Audio System."
Check 4: Cable Connections
Unplug and reconnect your audio cable. For optical cables, make sure you feel the connector click into place. For HDMI, verify you're using the ARC-labeled port on your TV.
Check 5: Audio Format (PCM)
Yes, this appears twice because it's that important. Change your TV's digital audio output to PCM.
Check 6: TV Speakers Disabled
Some TVs won't send audio to an external device unless you explicitly disable internal speakers. Look for a "TV Speakers On/Off" toggle in your TV's audio menu.
Check 7: Source Device Settings
If you're routing audio through a cable box, streaming device, or game console, that device may have its own audio output settings. Check that it's set to output audio to your TV (not Bluetooth headphones or another device).
Power Cycle Procedure:
When nothing else works, a full power cycle often resets stuck audio handshakes:
Turn off the soundbar
Unplug the soundbar from power
Turn off the TV
Unplug the TV from power
Wait 60 seconds (not 10 seconds - actually wait the full minute)
Plug in the TV first
Turn on the TV and wait for it to fully boot
Plug in the soundbar
Turn on the soundbar
Select the correct input source
Factory Reset (Last Resort):
If all else fails, reset your Insignia soundbar to factory defaults. On most models, press and hold the Power button and Volume Down button simultaneously for 5-10 seconds. The LED will flash, indicating a reset.
After resetting, you'll need to re-pair Bluetooth devices and possibly re-configure CEC settings.
For broader issues affecting your Insignia TV beyond soundbar connectivity, our comprehensive guide on how to fix Insignia TV problems covers power issues, picture problems, and more. And if you need to reset insignia tv factory settings to resolve persistent audio routing issues, that's covered there too.
HDMI ARC is fantastic when it works and frustrating when it doesn't. Here are the specific issues that cause ARC failures and how to fix them.
Common HDMI ARC Failure Causes:
Using the wrong HDMI port (non-ARC port)
CEC/HDMI-CEC disabled on TV
Incompatible or damaged HDMI cable
Outdated TV firmware
TV/soundbar handshake failure
Verify You're Using the ARC Port:
This bears repeating: only one or two HDMI ports on your TV support ARC. Look for the actual "ARC" label printed next to the port. HDMI 1 or HDMI 2 without an ARC label will NOT return audio to your soundbar.
CEC Naming by TV Brand:
HDMI-CEC goes by different names depending on your TV manufacturer. Make sure this setting is enabled:
TV Brand | CEC Name |
|---|---|
Samsung | Anynet+ |
LG | SIMPLINK |
Sony | BRAVIA Sync |
Vizio | CEC |
Roku TV | CEC |
Fire TV | CEC Device Control |
Philips | EasyLink |
Sharp | Aquos Link |
If you can't find CEC settings, search your TV's settings menu - most modern TVs have a search function.
HDMI Cable Troubleshooting:
Not all HDMI cables support ARC. You need a High Speed HDMI cable (version 1.4 or newer). Old Standard HDMI cables from 2008 or earlier won't work.
Try a different cable before assuming your equipment is faulty. Damaged cables cause intermittent audio dropouts that drive users crazy.
Check for Firmware Updates:
Outdated firmware on your TV or soundbar can cause CEC/ARC bugs. Check for updates:
TV: Settings → Support → Software Update (location varies by brand)
Soundbar: Insignia soundbars don't have user-updateable firmware, but ensuring your TV is updated often fixes compatibility issues
To update insignia tv software on Insignia Fire TV models, navigate to Settings → My Fire TV → About → Check for Updates.
ARC Handshake Reset:
Sometimes the TV and soundbar fail to establish the initial ARC handshake. A full power cycle (unplugging both devices for 60 seconds) usually forces a fresh handshake on reconnection.
When to Give Up on HDMI ARC:
If you've tried everything - correct port, CEC enabled, new cable, power cycles, firmware updates - and ARC still won't work, switch to optical. Optical provides nearly identical audio quality for most content and is significantly more reliable.
Some TV models have buggy ARC implementations that simply don't work well with third-party soundbars. Optical is a perfectly acceptable permanent solution, not just a workaround.
Audio that arrives before or after the video is distracting once you notice it. Here's why it happens and how to fix it.
Why Audio Gets Out of Sync:
Your TV processes video and audio separately. Video goes through scaling, motion smoothing, and display processing. Audio takes a different path to your soundbar, which does its own processing. If these paths take different amounts of time, lips don't match voices.
HDMI ARC typically has less delay than Bluetooth. Optical falls in between. But any connection can have sync issues depending on your specific equipment and settings.
Quick Sync Fix:
Set your TV's digital audio output to PCM. This reduces sync issues because your TV decodes the audio (less processing in the soundbar) and sends it as raw PCM data.
TV Audio Delay Settings:
Most modern TVs have a "Lip Sync," "Audio Delay," or "AV Sync" adjustment buried in the audio settings menu.
Navigate to your TV's audio settings and look for one of these options. Adjustments typically range from 0 to 300 milliseconds. Start at 0 and increase in small increments while watching dialogue-heavy content until lips and voices align.
Important limitation: Many TVs only allow you to delay audio further. If your audio is already behind the video (voices arrive late), delaying it more won't help. Some newer Samsung and LG TVs allow adjustment in both directions, but this isn't universal.
Soundbar Sync Settings:
Some soundbars have their own audio delay adjustments. Check your Insignia soundbar's manual to see if this feature is available on your model. If present, it's usually accessed through a button sequence on the remote.
Connection Method Impact:
If sync issues persist, try changing your connection method:
HDMI ARC: Usually the least delay
Optical: Moderate delay
Bluetooth: Most delay (40-200ms typical)
Switching from Bluetooth to HDMI ARC often eliminates lip sync problems entirely.
Gaming Considerations:
For gaming, enable "Game Mode" on your TV. This disables most video processing (motion smoothing, picture enhancement) that causes display delay. You may need separate audio delay profiles for gaming vs. movie watching.
If you game frequently, enable insignia tv game mode for reduced input lag that also helps with audio sync.
When Sync Can't Be Fixed:
Bluetooth inherently has latency due to how wireless audio compression works. If perfect lip sync is critical, use a wired connection instead.
Some streaming content has sync issues baked into the source material itself. If the problem only occurs on one streaming service or one show, the issue might not be your equipment at all.
Bluetooth pairing usually works smoothly, but when it doesn't, the fixes are straightforward.
Soundbar Won't Enter Pairing Mode:
If pressing the Source button doesn't get you to blinking blue (pairing mode), the soundbar may still be connected to a previous device. Hold the Bluetooth button for 3-5 seconds to force pairing mode. On some models, holding Source for 3 seconds achieves the same result.
Soundbar Not Showing Up in Device List:
Make sure the soundbar LED is blinking blue, not solid blue. Blinking means "searching for new connection." Solid means "already connected to something."
Stay within 30 feet of the soundbar and remove obstacles between the soundbar and your TV/phone. Walls and furniture reduce Bluetooth signal strength.
Refresh your TV's or phone's Bluetooth device list. Some devices cache old scan results and need a manual refresh.
Pairing Keeps Failing:
If pairing repeatedly fails, reset the soundbar's Bluetooth memory with a factory reset (Power + Volume Down for 5-10 seconds). This clears all previously paired devices and gives you a fresh start.
Some TVs have Bluetooth that only supports headphones, not speakers. Check your TV's documentation to verify it supports Bluetooth audio output to speakers.
Soundbar Keeps Disconnecting:
Bluetooth interference from WiFi routers, microwaves, and other Bluetooth devices can cause dropouts. Move the soundbar away from your router if possible.
Low batteries in the soundbar remote won't affect Bluetooth connectivity, but a failing power supply can cause random disconnections. If the soundbar disconnects frequently, try a different power outlet.
Subwoofer Pairing (2.1 Systems):
For NS-HTSB2123 and other 2.1 systems with wireless subwoofers, the subwoofer should pair automatically when you plug it in. If it doesn't:
Unplug both soundbar and subwoofer
Plug in the soundbar first and turn it on
Plug in the subwoofer within 30 seconds
The pairing indicator on the subwoofer should turn solid turquoise
If you're also experiencing remote pairing issues on your Insignia Fire TV, those problems are often related - you might need to fix insignia remote pairing separately.
Getting sound is step one. Getting good sound requires a few more adjustments.
Sound Mode Selection:
Most Insignia soundbars have three sound modes accessible via the remote:
Standard: Balanced sound for general TV watching and music
Theater: Enhanced bass and pseudo-surround effect for movies
News: Optimized for dialogue clarity - reduces background frequencies to make voices stand out
Press the sound mode button on your remote to cycle through these options. There's no on-screen display, so listen for the difference between modes.
When to Use Each Mode:
Use Standard for everyday TV, late-night watching (less boomy bass), and music streaming. Theater mode works best for action movies and content with lots of sound effects. News mode is ideal for talk shows, news programs, and anything where you're straining to understand dialogue.
Bass Adjustment:
Press the Bass button on your remote, then use the volume up/down buttons to adjust bass level. Finding the right bass level depends on your room and personal preference - start at the default and adjust from there.
More bass isn't always better. In small rooms, excessive bass sounds muddy and can actually make dialogue harder to understand.
TrueVolume Feature:
Some Insignia soundbars have a TrueVolume function that normalizes volume across different content. This prevents commercials from blasting you and keeps dialogue audible during quiet scenes.
Enable TrueVolume if you frequently switch between different content types or channels. Disable it for music listening where you want the natural dynamics preserved.
Optimal Placement:
Position your soundbar directly below (or above) your TV screen, centered horizontally. The soundbar should be at ear level when you're seated.
Don't place the soundbar inside a cabinet. The enclosed space muffles sound and can cause bass frequencies to boom unpleasantly.
Wall mounting? Use the included hardware. The soundbar sounds slightly different mounted vs. sitting on a surface due to acoustic reflection, so re-evaluate your sound mode and bass settings after mounting.
Room Acoustics Tips:
Hard surfaces (tile, glass, bare walls) reflect sound and can make audio harsh. Soft surfaces (carpet, curtains, upholstered furniture) absorb sound and create a warmer listening experience.
If your room is very reverberant (lots of echo), try Theater mode with reduced bass. If your room is heavily furnished and "dead" sounding, Standard mode with increased bass might help.
For the best overall experience, combine soundbar optimization with optimal picture settings. You can optimize insignia picture settings through your TV's display menu for a matched audio-visual experience.
Using one remote instead of two is genuinely convenient. Here's how to set it up.
HDMI-CEC Automatic Control:
When connected via HDMI ARC with CEC enabled on your TV, the TV remote should automatically control soundbar volume. This works because CEC allows devices to send commands over the HDMI cable.
If volume control isn't working, verify:
Soundbar is connected to the TV's HDMI ARC port
CEC is enabled on your TV (Anynet+, SIMPLINK, BRAVIA Sync, etc.)
Soundbar is in HDMI/ARC input mode (white LED)
IR Learning Function:
Insignia soundbars can "learn" button codes from other remote controls, allowing your TV remote to control the soundbar even without CEC.
To program IR learning:
Press and hold the button you want to teach on the soundbar remote until the LED blinks
Point your TV remote at the soundbar's IR sensor
Press the corresponding button on your TV remote
The soundbar LED will flash green to confirm the button was learned
Repeat for other buttons you want to program
Not all remote controls are compatible with IR learning. Test your TV remote before relying on this feature.
Universal Remote Programming:
Insignia soundbars work with most universal remotes. Common Insignia soundbar codes include:
1292
2891
3165
1144
Try each code until volume and mute functions work correctly.
Cable/Satellite Remote Codes:
For Xfinity remotes, Insignia soundbar codes are typically in the 31XXX range. The exact code depends on your remote model - check Xfinity's code lookup tool or try auto-search programming.
If you need detailed instructions for programming your cable remote, including specific steps to pair xfinity remote with insignia equipment, those are available in our dedicated remote setup guides.
For Roku TV users who want everything controlled from one remote, the process to pair roku remote with insignia TV handles both TV and soundbar control when CEC is properly configured.
What Can't Be Controlled Remotely:
Even with CEC or IR learning, some functions always require the soundbar's own remote:
Sound mode changes (Standard/Theater/News)
Bass level adjustment
Bluetooth pairing mode
Input source switching (though some CEC implementations handle this)
Keep the soundbar remote accessible - you'll need it occasionally.

NS-SB314: The soundbar featured in some older online guides is discontinued. It had optical and Bluetooth but no HDMI. If you have this model, follow the optical connection instructions.
NS-SB212: Another discontinued budget model with limited connectivity. Follow optical instructions if you're still using this soundbar.
Yes, if your projector has HDMI ARC, optical output, or a 3.5mm audio output. Connect using the appropriate method based on available ports. Most projectors have optical or 3.5mm audio outputs even if they lack HDMI ARC.
Absolutely. Connect your console to the TV via HDMI, then route audio from the TV to the soundbar using HDMI ARC or optical. The soundbar will play all console audio. For the lowest latency, use HDMI ARC with CEC and enable Game Mode on your TV.
Yes, but not simultaneously. The soundbar has multiple input options (HDMI, optical, Bluetooth, AUX), and you can connect a different device to each. Press Source to switch between connected devices. Only one input plays at a time.
Your TV speakers aren't disabled. Go to your TV's audio settings and turn off internal speakers or set audio output to "External Speakers Only." Some TVs require you to manually disable TV speakers when using an external audio device.
Navigate to your TV's audio settings (the exact path varies by brand - see TV-Brand Settings section above). Look for "TV Speakers," "Internal Speakers," or "Speaker Output." Set this to "Off" or select "External Speakers" as the only output.
No, the NS-HTSB22 and NS-HSB318 do not support adding an external subwoofer. They're designed as standalone units without a dedicated subwoofer output. If you want more bass, consider the NS-HTSB2123 which includes a wireless subwoofer.
For Dolby Digital support, use optical connection with your TV set to output Dolby Digital (not PCM). However, many Insignia soundbars cannot decode Dolby Digital internally - if you get no sound, switch your TV to PCM output. The soundbar won't play true Dolby surround sound, but PCM stereo from Dolby sources still sounds good.
Auto-standby is likely enabled. If the soundbar doesn't receive an audio signal for a certain period (usually 15-20 minutes), it automatically enters standby mode to save power. Some TVs also send power-off commands via CEC when they shut down. This is normal behavior.
Yes. Power on the soundbar, select Bluetooth input (blinking blue LED), pair with your phone or tablet, and stream music directly. The soundbar functions as a standalone Bluetooth speaker in this mode.
Best Buy sells replacement Insignia remotes, or search for "NS-HTSB22 remote" on Amazon. Generic universal remotes also work if programmed with Insignia codes. In the meantime, you can control basic functions using buttons on the soundbar itself.
No, Insignia soundbars don't have a companion app for control or configuration. All settings are managed through the physical remote and soundbar buttons.
Yes, mounting hardware is included with most Insignia soundbar models. The soundbar has keyhole slots on the back for wall mounting. Mount directly below your TV for best audio alignment. Leave a few inches of clearance from the TV for proper ventilation and sound projection.
Connecting an Insignia soundbar to your TV doesn't have to be complicated. Here's what matters most:
Use HDMI ARC if possible. It provides the best audio quality and lets your TV remote control the soundbar volume. Connect to the correct ARC-labeled HDMI port, enable CEC on your TV, and you're set.
Optical is your reliable backup. When HDMI ARC won't cooperate - and sometimes it just won't - optical gives you nearly identical audio quality with more straightforward setup.
PCM is the magic setting. If you're getting no sound or strange audio issues, changing your TV's digital audio output to PCM resolves the problem more often than not. This single setting change fixes about 70% of Insignia soundbar audio issues.
Match the LED to your connection. White for HDMI ARC, green for optical, blue for Bluetooth, orange for AUX. If the LED doesn't match your connection method, the soundbar isn't listening to the right input.
Save this guide - settings occasionally reset after power outages or TV firmware updates, and you'll want a reference handy.
