Getting your Sonos soundbar working with your Samsung TV shouldn't feel like solving a puzzle. Yet here you are, staring at cables, menus, and settings wondering why there's no sound coming out of that beautiful speaker you just unboxed.
I've connected Sonos soundbars to dozens of Samsung TVs - everything from 2018 models to the latest 2025 Neo QLEDs - and the process is genuinely straightforward once you know where Samsung hides certain settings. The trick is understanding that Samsung calls HDMI-CEC "Anynet+" and that the menu paths change depending on your TV's model year.
This guide walks you through every connection method, troubleshoots the most common issues (including the dreaded "no sound" problem), and helps you get the absolute best audio quality from your setup. Whether you've got an Arc Ultra, Beam Gen 2, or Ray, you'll have your system working in minutes.
Quick Start: Connect Sonos to Samsung TV in 5 Minutes
Before diving into detailed setup procedures, let's get you connected fast. If you're comfortable with basic TV settings and just need the essential steps, this section covers everything you need to connect Sonos to Samsung TV and start enjoying better audio immediately.
Compatibility Check
Every current Sonos home theater product works with Samsung TVs:
Sonos Arc Ultra ($999) – Flagship with Sound Motion technology
Sonos Arc ($899, often discounted) – Premium Dolby Atmos
Sonos Beam Gen 2 ($499) – Best mid-range option

Which Sonos Soundbar Works Best With Samsung TV?
Choosing the right Sonos soundbar depends on your room size, TV features, and budget. Every model connects identically to Samsung TVs, but the audio experience varies significantly. Let me break down which option makes sense for different setups.
Sonos Soundbar Comparison for Samsung TVs
Model | Price | Dolby Atmos | Room Size | Best For |
|---|---|---|---|---|
Arc Ultra | $999 | Yes (9.1.4) | 20m²+ | Premium home theater, large rooms |
Arc | $899 (often ~$599 on sale) | Yes | 18m²+ | Value seekers wanting full Atmos |
Beam Gen 2 | $499 | Yes (virtual) | 12-20m² | Most Samsung TV owners |
Ray | $279 | No | Under 12m² | Bedrooms, small spaces |
Sonos Arc Ultra: The Flagship Choice
The Arc Ultra represents Sonos's best soundbar technology. Its Sound Motion woofer delivers bass that rivals setups with a separate subwoofer, and the 14-driver array creates genuine three-dimensional sound.
For Samsung TVs with eARC (2020 T-series and newer), the Arc Ultra unlocks its full potential with lossless Dolby Atmos. The dedicated upward-firing and side-firing drivers create height channels that budget soundbars simply can't replicate.
The Arc Ultra makes sense if you have a living room larger than 20 square meters, watch lots of movies and immersive content, and don't mind the premium price tag.
Sonos Beam Gen 2: The Sweet Spot
Here's what most people buying a Sonos for their Samsung TV should consider: the Beam Gen 2 hits an excellent balance between price and performance.
At $499, you get Dolby Atmos support through psychoacoustic processing (rather than physical upward-firing drivers), clear dialogue enhancement, and enough power for medium-sized rooms. The compact size (25.6 inches) fits under most TVs without overwhelming your entertainment center.
The Beam Gen 2 works beautifully with Samsung QLED, Neo QLED, and Crystal UHD TVs in typical living room setups. If your Samsung has HDMI ARC but not eARC, you'll still get Dolby Digital Plus Atmos - the lossy version that sounds excellent for streaming content.
Sonos Ray: Budget-Friendly Basics
The Ray does one thing well: it makes your Samsung TV sound significantly better than the built-in speakers for $279.
No Dolby Atmos support means you're limited to stereo and Dolby Digital 5.1. The Ray connects via optical only (no HDMI port), which simplifies setup but eliminates CEC remote control. You'll need to configure IR learning in the Sonos app if you want your Samsung remote to control volume.
Consider the Ray for bedroom TVs, gaming setups where you prioritize low latency, or secondary viewing areas where premium audio isn't essential.
Samsung-Specific Recommendations
If your Samsung TV has eARC: Invest in the Arc Ultra or Beam Gen 2 to take advantage of higher-bandwidth audio. Samsung TVs from 2020 onward (including all Neo QLED, QLED, OLED, Frame, and Crystal UHD models) support eARC.
If your Samsung TV only has ARC: The Beam Gen 2 offers the best value - you'll get Dolby Atmos via Dolby Digital Plus, which sounds excellent for streaming content from Netflix, Disney+, and Apple TV+.
If you want to expand later: All Sonos soundbars support adding a Sub (or Sub Mini) and surround speakers (Era 100 or Era 300). The Arc Ultra paired with Sub 4 and Era 300 surrounds creates a legitimate home theater experience.

How to Connect Sonos to Samsung TV Using HDMI ARC
HDMI ARC (Audio Return Channel) is the standard connection method for Sonos soundbars and Samsung TVs. This setup enables two-way communication: your TV sends audio to the Sonos, while your Samsung remote controls the soundbar's volume through HDMI-CEC.
Finding Your Samsung TV's HDMI ARC Port
Samsung TVs typically designate HDMI 3 as the ARC port, though this varies by model year. Look for one of these labels on the back panel:
"HDMI 3 (ARC)"
"ARC" printed beneath the port
"eARC/ARC" on newer models
On Samsung Frame TVs and select premium models, ports are located on the One Connect Box rather than the TV itself.
Step-by-Step HDMI ARC Connection
Step 1: Power off your Samsung TV and Sonos soundbar completely - not just standby mode.
Step 2: Locate the HDMI ARC port on your Samsung TV's back panel. On most models, it's the third HDMI input from the left.
Step 3: Connect the HDMI cable (included with your Sonos) to the TV's ARC port. Use the Sonos-supplied cable - it's certified for ARC compatibility and prevents potential handshake issues.
Step 4: Connect the other end of the HDMI cable to your Sonos soundbar. The Arc, Arc Ultra, and Beam have a single HDMI port, making this foolproof.
Step 5: Power on your Samsung TV first, wait for it to fully boot, then power on the Sonos soundbar.
Step 6: Enable Anynet+ (HDMI-CEC) on your Samsung TV. The menu path varies by model year:
2025 models: Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC)
2023-2024 models: Settings > All Settings > Connection > External Device Manager > Anynet+ (HDMI-CEC)
2022 models: Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC)
2017-2021 models: Settings > General > External Device Manager > Anynet+
Step 7: Configure Sound Output by navigating to Settings > Sound > Sound Output. Select "Receiver (HDMI)" or your Sonos device name if it appears.
Step 8: Open the Sonos app and complete the TV setup wizard. The app will verify your connection and guide you through Trueplay tuning.
Verifying Your Connection
After setup, test your connection:
Play any content on your Samsung TV
Check the Sonos app's "Now Playing" screen - it should show your TV as the source
Use your Samsung remote's volume buttons - the Sonos LED should light up, confirming CEC control
If the connection seems unstable or you're experiencing issues, a Samsung HDMI connection reset often resolves handshake problems. Check that Samsung Anynet+ Sonos not working issues aren't caused by conflicting CEC devices.
HDMI ARC Audio Format Support
HDMI ARC on Samsung TVs supports:
Dolby Digital (5.1 surround)
Dolby Digital Plus (lossy Dolby Atmos)
PCM Stereo
You won't get lossless Dolby Atmos (TrueHD) through ARC - that requires eARC, covered in Section 4. For most streaming content from Netflix, Disney+, and Amazon Prime Video, Dolby Digital Plus delivers excellent audio quality.
If your TV isn't detecting the Sonos at all, check out our guide on Samsung TV no signal issues for port-related troubleshooting.
HDMI eARC Setup: Unlock Dolby Atmos on Samsung TV
If your Samsung TV has eARC (Enhanced Audio Return Channel), you can unlock the highest-quality audio formats, including lossless Dolby Atmos using the TrueHD codec. This section covers Samsung eARC Sonos setup for optimal audio performance.
Understanding eARC vs. ARC
The key differences matter for audio quality:
Feature | ARC | eARC |
|---|---|---|
Bandwidth | ~1 Mbps | ~37 Mbps |
Dolby Atmos | Lossy (DD+) only | Lossless (TrueHD) |
Lip Sync | Manual correction often needed | Automatic correction |
Audio Formats | Dolby Digital, DD+ | All formats including DTS:X* |
*Note: Samsung TVs don't support DTS:X passthrough, but eARC does support it on other TV brands.
Which Samsung TVs Have eARC?
Samsung added eARC support starting with 2020 models:
2020 (T models): All QLED 8K, QLED 4K, UHD, Frame, Serif, Terrace, Sero
2021 (A models): All QLED and UHD models, Frame (except 32")
2022 (B models): All Neo QLED 8K/4K, S95B OLED, all QLED 4K, Frame (except 32")
2023-2026: All Neo QLED, QLED, OLED, Crystal UHD, and Frame TVs
To verify your TV supports eARC: Settings > Support > About This TV.
Step-by-Step eARC Configuration
Step 1: Verify your Samsung TV has eARC capability using the method above.
Step 2: Use an Ultra High Speed HDMI cable or Premium High Speed HDMI cable certified for eARC (HEAC or HEC). The cable included with Sonos Arc Ultra and Beam Gen 2 meets this specification.
Step 3: Connect your Sonos soundbar to the HDMI eARC port on your Samsung TV (same physical port as ARC, usually HDMI 3).
Step 4: Enable Anynet+ (HDMI-CEC) following the menu paths in Section 3.
Step 5: Configure eARC Mode by navigating to Settings > Sound > Expert Settings > HDMI eARC Mode. Set this to Auto.
Step 6: Set Digital Output Audio Format by going to Settings > Sound > Expert Settings > Digital Output Audio Format. Choose Auto or Pass-Through for the highest quality.
Step 7: Enable Dolby Atmos Compatibility (if available) in Expert Settings. On supported Samsung TVs, you'll find a "Dolby Atmos Compatibility" toggle - switch this ON.
Step 8: Verify in the Sonos app by playing Dolby Atmos content. The "Now Playing" screen should display "Dolby Atmos" when receiving an Atmos signal.
HDMI Cable Requirements for eARC
Don't use old HDMI cables for eARC connections. You need:
Ultra High Speed HDMI (HDMI 2.1, 48Gbps)
Premium High Speed HDMI (HDMI 2.0, 18Gbps with HEC)
HEAC (High-Speed HDMI with Ethernet Audio Channel)
The cable included with your Sonos soundbar meets these specifications. Using uncertified cables can cause intermittent dropouts, handshake failures, or complete loss of audio.
Getting Dolby Atmos from Streaming Services
For Dolby Atmos content to reach your Sonos:
Source content must be Atmos-encoded. Not all content on Netflix, Disney+, or Amazon has Atmos audio - check the content details.
Your streaming subscription may need to support Atmos. Netflix Basic, for example, doesn't include Dolby Atmos.
Use original language audio tracks. Dubbed tracks often lose Atmos encoding.
Known Samsung Limitation: Some Samsung TV models don't output Dolby Atmos from the native Disney+ app, even when the TV supports eARC. The workaround is using an external streaming device like Apple TV 4K or Amazon Fire TV Cube connected via HDMI passthrough.
If audio seems out of sync after enabling eARC, check our guide on Samsung TV audio out of sync for lip-sync adjustment. You may also want to ensure your Samsung TV firmware update is current, as eARC bugs are frequently patched.
Understanding your Samsung TV sound settings helps optimize the audio chain from content source to your Sonos. You can also adjust Samsung TV digital audio output settings for fine-tuned control.
Samsung Anynet+ (HDMI-CEC) Configuration for Sonos
Anynet+ is Samsung's implementation of HDMI-CEC (Consumer Electronics Control) - the technology that lets your devices communicate over HDMI. For Sonos soundbars, Anynet+ enables volume control via your Samsung remote and automatic audio routing.
Why Anynet+ Is Required
Without Anynet+ enabled:
Your Samsung remote won't control Sonos volume
Audio may not automatically route to the soundbar
Power synchronization won't work (TV on = Sonos on)
Voice assistant TV commands will fail
Enabling Anynet+ by Samsung TV Model Year
Samsung has moved the Anynet+ setting location several times. Here's where to find it:
2025 models: Settings > All Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC)
2023-2024 models: Settings > All Settings > Connection > External Device Manager > Anynet+ (HDMI-CEC)
2022 models: Settings > General & Privacy > External Device Manager > Anynet+ (HDMI-CEC)
2017-2021 models: Settings > General > External Device Manager > Anynet+
2016 and older: Settings > System > Expert Settings > Anynet+
Anynet+ Settings to Configure
Once you've found Anynet+, configure these settings:
Anynet+ (HDMI-CEC): ON
Auto Turn Off: ON (optional - turns off connected devices when TV powers off)
Search for Devices: Run this if your Sonos isn't immediately detected
CEC Device Limits and Conflicts
Samsung supports up to 12 HDMI-CEC devices, with a maximum of 3 devices of the same type. In practice, CEC conflicts commonly occur when multiple devices compete for control.
Common CEC Conflict Sources:
Apple TV: Often tries to control TV power and input
Amazon Fire Stick/Cube: Can conflict with soundbar CEC
PlayStation/Xbox: Game consoles sometimes intercept CEC commands
Chromecast: Known to cause CEC instability
Resolution Options:
Disable CEC on the problematic device in its settings menu
Use a CEC-less HDMI adapter ($10-15) on the conflicting device's HDMI cable
Disconnect devices one by one to identify the culprit
If your Samsung TV turns on by itself, CEC from a connected device is often the cause - particularly streaming sticks that wake the TV when receiving updates.
Troubleshooting Anynet+ Issues
If Anynet+ isn't detecting your Sonos:
Disconnect all HDMI devices except the Sonos
Disable Anynet+, restart your TV
Re-enable Anynet+
Connect only the Sonos and test
Add other devices one at a time
For first-time Samsung TV owners, our complete Samsung TV initial configuration guide covers all essential settings including Anynet+.
Connect Sonos to Samsung Frame TV (One Connect Box Guide)
Samsung Frame TVs use a unique architecture that separates the display panel from its connection ports. Understanding this design is essential for connecting your Sonos soundbar properly.
Understanding the One Connect Box
The One Connect Box is an external hub that houses all HDMI ports, USB ports, antenna connections, and the power input for Frame TVs. It connects to the actual TV panel via a nearly invisible One Connect cable - that's how Samsung achieves the "picture frame" aesthetic with minimal visible wiring.
For Sonos setup, this means your soundbar connects to the One Connect Box, not the TV itself.
Locating the ARC Port on One Connect Box
The One Connect Box typically places the HDMI ARC/eARC port at position 3 (labeled "HDMI 3 (ARC)" or "HDMI 3 (eARC/ARC)" on newer boxes).
The box can be positioned:
Behind furniture
In a cabinet
In an adjacent room (the One Connect cable extends several meters)
This flexibility is excellent for cable management - you can hide the One Connect Box with your Sonos soundbar while keeping the Frame TV mounted cleanly on your wall.
Step-by-Step Frame TV Connection
Step 1: Locate your One Connect Box. If you haven't set up your Frame TV yet, the box ships in the same packaging and connects via the transparent One Connect cable.
Step 2: Find HDMI 3 (ARC) on the One Connect Box - it's typically on the right side when viewing the ports.
Step 3: Connect the Sonos HDMI cable to HDMI 3 (ARC) on the One Connect Box.
Step 4: Connect the other end to your Sonos soundbar.
Step 5: Configure Anynet+ and Sound Output using the same steps from Sections 3 and 5.
Step 6: Position your Sonos soundbar where it can receive IR signals if you plan to use IR remote control. The Samsung One Remote sends commands via Bluetooth to the One Connect Box, which then transmits IR - so placement matters for responsiveness.
Cable Management Tips for Frame TV + Sonos
The Frame TV's aesthetic appeal depends on clean cable management:
Use the One Connect Box location strategically. Place it in a cabinet or media console alongside your Sonos soundbar.
Consider wall-mounting the soundbar. The Sonos Arc and Arc Ultra have optional wall mounts that complement the Frame's gallery aesthetic.
Hide cables in-wall. Since the One Connect cable is designed to be nearly invisible, running it through walls is easier than standard HDMI setups.
For more details on Samsung TV connections and Samsung TV power input location, particularly for Frame TV installations, check our dedicated guide. Understanding Samsung TV remote functions helps you configure universal control for your Sonos.
Alternative Connection: Optical Audio Setup
If HDMI ARC isn't working reliably, or you're using an older Samsung TV without ARC support, optical audio provides a stable alternative. The Sonos Ray has a built-in optical port, while the Arc, Arc Ultra, and Beam include an optical-to-HDMI adapter.
When to Use Optical
Optical audio makes sense when:
Your Samsung TV predates HDMI ARC (pre-2017 models)
You're experiencing persistent ARC handshake issues
CEC conflicts can't be resolved
Your setup includes legacy equipment that disrupts HDMI communication
What You Lose with Optical
Before switching to optical, understand the limitations:
No Dolby Atmos (limited to Dolby Digital 5.1)
No CEC remote control (must use IR learning in Sonos app)
No automatic power sync between TV and soundbar
Maximum 5.1 channel audio (no high-resolution formats)
Step-by-Step Optical Connection
Step 1: Locate the Digital Audio Out (Optical) port on your Samsung TV - it's usually near the HDMI ports and may be labeled "TOSLINK" or "S/PDIF."
Step 2: For Sonos Ray: Connect an optical cable directly to the Ray's optical input.
Step 3: For Arc, Arc Ultra, or Beam: Attach the included optical-to-HDMI adapter to the optical cable, then connect the adapter to the soundbar's HDMI port.
Step 4: On your Samsung TV, navigate to Settings > Sound > Sound Output and select "Optical" or "Digital Audio Out."
Step 5: Configure Samsung TV digital audio output format to "Dolby Digital" or "Auto" in Expert Settings.
Step 6: Set up IR remote control in the Sonos app:
Go to Settings > System > [Your Sonos] > TV Settings
Select "Remote Control Setup"
Point your Samsung remote at the Sonos soundbar
Press volume buttons when prompted to teach the Sonos your remote's IR signals
Optical Audio Quality
Despite its limitations, optical delivers clean digital audio. For watching TV shows, news, and casual movies, you won't notice a dramatic difference from HDMI ARC. The difference becomes apparent with immersive content specifically mixed for Dolby Atmos.
Sonos Samsung TV No Sound: Complete Troubleshooting Guide
The "connected but no sound" issue is the most common problem when pairing Sonos soundbars with Samsung TVs. After troubleshooting this across dozens of setups, here's a systematic approach that resolves the problem 90%+ of the time.
60-Second Quick Fixes
Try these first - they solve most cases:
Check Sound Output setting. Navigate to Settings > Sound > Sound Output. If it shows "TV Speaker," change it to "Receiver (HDMI)" or your Sonos device name.
Verify Anynet+ is enabled. Settings > General > External Device Manager > Anynet+ (HDMI-CEC) must be ON.
Confirm HDMI cable is in the ARC port. A cable in a regular HDMI port won't transmit audio to the soundbar.
Check the Sonos app. The "Now Playing" screen should show your TV as the active source. If it shows "TV" but no audio plays, the connection exists but audio routing has failed.
Change the channel or app. Sometimes switching content triggers the audio handshake.
If these don't work, proceed to the power cycle sequence.
Power Cycle Sequence
A proper power cycle resolves handshake issues that develop over time:
Unplug your Samsung TV's power cable from the wall - don't just use the remote
Unplug your Sonos soundbar's power cable
Wait 2 full minutes (this allows capacitors to discharge completely)
Reconnect the TV first and wait for it to fully boot (you'll see the Samsung logo)
Reconnect the Sonos soundbar and wait for the white LED to indicate readiness
Test audio playback
This sequence works because HDMI-CEC handshakes sometimes get "stuck" in an invalid state. A complete power cycle forces both devices to renegotiate their connection. If your restart frozen Samsung TV doesn't respond to normal power commands, a hard reset may be necessary.
HDMI Handshake Reset
If power cycling doesn't work, try a complete HDMI handshake reset:
Disconnect ALL HDMI devices from your Samsung TV
Navigate to Settings > General > External Device Manager and disable Anynet+
Reboot your Samsung TV
Re-enable Anynet+ after the TV restarts
Connect ONLY your Sonos soundbar to the ARC port
Wait 60 seconds for the HDMI handshake to complete
Test audio before connecting any other devices
Add other HDMI devices one at a time, testing after each
This process isolates whether another device is causing CEC conflicts. For persistent handshake problems, our guide on Samsung HDMI-CEC reset covers advanced troubleshooting.
Audio Format Troubleshooting
Sometimes the issue is audio format compatibility:
Navigate to Settings > Sound > Expert Settings > Digital Output Audio Format
Change from "Auto" to "PCM"
Test audio playback
If PCM works but Auto doesn't, your source content may be using an unsupported format. Sonos soundbars don't support DTS audio formats - common on Blu-ray discs. Samsung TVs also don't pass through DTS to external soundbars.
Once you've confirmed PCM works, try:
"Dolby Digital" for 5.1 surround
"Dolby Digital Plus" or "Auto" for Atmos content
CEC Conflict Resolution
If your Sonos audio drops intermittently or the TV keeps switching back to internal speakers:
Identify the conflicting device: Disconnect HDMI devices one by one until the problem stops
Disable CEC on that device: Check its settings for HDMI-CEC, HDMI Control, or similar options
Use a CEC-less adapter: If you can't disable CEC on the device, a $10-15 HDMI CEC blocker prevents it from interfering with your Sonos
Common culprits include Apple TV (turn off "Control TVs and Receivers"), Amazon Fire devices, and gaming consoles.
Factory Reset (Last Resort)
If nothing else works:
Sonos Factory Reset:
Unplug the soundbar
Press and hold the Join button (or Connect button on older models)
While holding the button, plug the power cable back in
Keep holding until the LED flashes orange and white
Release and wait for the soundbar to reset
Samsung TV Reset: Settings > General > Reset (you'll need your PIN, default is 0000)
After resetting, you'll need to reconfigure everything from scratch - but this often resolves deep-seated firmware conflicts.
For general Samsung TV troubleshooting or diagnose Samsung TV issues beyond audio, check our comprehensive troubleshooting resource. If your Samsung TV software is outdated, update Samsung TV system to the latest firmware version.
When audio cuts out intermittently rather than failing completely, our guide on Samsung TV intermittent audio addresses that specific symptom.
Fix Sonos Disconnecting From Samsung TV
Unlike the "no sound" issue, disconnection problems involve a working setup that randomly fails. The audio works fine, then suddenly your Samsung TV switches back to internal speakers, or the Sonos stops receiving signal altogether.
Common Causes of Disconnection
CEC Conflicts: Other HDMI devices competing for control HDMI Cable Quality: Degraded or non-certified cables Firmware Bugs: Both Samsung and Sonos have released firmware that caused compatibility issues Power Saving Settings: Energy-saving features that disable HDMI ports
CEC Conflict Solutions
Identify the problematic device by disconnecting HDMI devices one at a time while monitoring for disconnections over 24-48 hours.
Once identified:
Access the device's settings and look for HDMI-CEC, HDMI Control, or device control options
Disable CEC features like "TV input switching" and "power control"
Test stability for at least 24 hours
If you can't disable CEC on the problematic device, use a CEC-less HDMI adapter. These small adapters block the CEC pin in the HDMI cable, preventing interference while allowing normal video/audio passthrough.
Cable Quality Issues
Check your HDMI cable:
Use the Sonos-supplied cable whenever possible - it's certified for ARC/eARC
Inspect for damage: Bent pins, kinked cables, or damaged connectors cause intermittent issues
Test a different cable: Swap with a known-good certified HDMI cable
Check connection tightness: Gently wiggle each end - a loose connection causes dropouts
Firmware Compatibility
Both Samsung and Sonos occasionally release firmware that causes compatibility problems.
Samsung firmware 1520.7 (August 2023) notably caused disconnection issues with Sonos Beam Gen 2. This was resolved in subsequent updates, but similar issues can recur.
To check and update:
Samsung: Settings > Support > Software Update > Update Now
Sonos: The app automatically updates firmware, but check Settings > System > System Updates
Before updating, search the Sonos Community forums for reports of issues with your specific Samsung TV model and the latest firmware versions.
Power Saving Settings
Disable power-saving features that affect HDMI:
Settings > General > Eco Solution > turn off power-saving modes that affect external devices
Settings > General > System Manager > disable automatic power-off timers
In the Sonos app, ensure the soundbar isn't set to auto-sleep
If your Samsung TV constant freeze occurs alongside Sonos disconnections, you may be dealing with a broader system stability issue. When the stop Samsung TV from rebooting guide applies, address that first before troubleshooting Sonos-specific issues.
Optimize Samsung TV Audio Settings for Sonos
Getting sound to your Sonos is step one. Optimizing that sound requires configuring your Samsung TV's audio settings correctly.
Recommended Audio Settings
Navigate to Settings > Sound > Expert Settings on your Samsung TV:
Setting | Recommended Value | Notes |
|---|---|---|
Sound Output | Receiver (HDMI) | Ensures audio routes to Sonos |
HDMI eARC Mode | Auto | Enables eARC when available |
Digital Output Audio Format | Auto or Pass-Through | Pass-Through for highest quality |
Dolby Atmos Compatibility | ON | If your TV has this option |
Auto Volume | OFF | Let Sonos handle volume normalization |
Digital Output Audio Format Options
Understanding what each setting does:
PCM: Uncompressed stereo audio - use this for troubleshooting only
Dolby Digital: 5.1 surround, compatible with everything
Dolby Digital Plus: Lossy Dolby Atmos support (via ARC)
Auto: TV selects format based on content and connection
Pass-Through: Sends original audio format without processing (best for eARC)
For most users with HDMI eARC connections, Auto or Pass-Through delivers the best results. If you experience audio dropouts with these settings, step down to Dolby Digital for stability.
Audio Delay (Lip Sync) Adjustment
If dialogue doesn't match actors' lips:
Navigate to Settings > Sound > Expert Settings > Audio Delay
Adjust in 10ms increments until audio syncs with video
Test with dialogue-heavy content for accurate calibration
The Sonos app also has an Audio Delay setting:
Open Settings > System > [Your Sonos] > TV Settings > Audio Delay
Usually, adjusting either the TV or the Sonos setting is sufficient - you shouldn't need to adjust both. For persistent sync issues, our Samsung TV lip sync delay guide provides detailed calibration steps.
Q-Symphony Note
Samsung's Q-Symphony feature - which plays audio through both TV speakers and a soundbar simultaneously - only works with Samsung soundbars. It's incompatible with Sonos.
When using Sonos, ensure your Sound Output is set to "Receiver (HDMI)" only. If Q-Symphony settings appear, they won't affect your Sonos setup.
Volume Optimization
If your Sonos sounds quiet even at high volume, check:
TV volume level: Some Samsung TVs output reduced volume to HDMI ARC. Try increasing TV volume in addition to Sonos volume.
Loudness setting in Sonos app: Settings > System > [Your Sonos] > Loudness (toggle ON for fuller sound at lower volumes)
Night Sound setting: Make sure the moon icon in the Sonos app is OFF unless you specifically want compressed dynamic range.
For overall volume issues, our guide on how to boost Samsung TV audio covers TV-side optimization.
Samsung Remote Control Setup With Sonos
One of the best features of connecting Sonos via HDMI ARC is single-remote control. Your Samsung remote can control Sonos volume without picking up a second remote or using the Sonos app.
CEC Volume Control (Automatic Method)
With Anynet+ enabled and HDMI ARC properly connected:
Press volume up/down on your Samsung remote
The Sonos LED should pulse white, indicating volume adjustment
Volume changes happen on the Sonos, not the TV
If this doesn't work immediately:
Open the Sonos app
Go to Settings > System > [Your Sonos] > TV Settings
Run "TV Setup" again to reinitialize CEC communication
Test volume control after setup completes
IR Learning Setup (For Optical Connections)
When using optical audio, CEC isn't available. You'll need to teach your Sonos the Samsung remote's IR signals:
Step 1: Open the Sonos app and navigate to Settings > System > [Your Sonos] > TV Settings
Step 2: Select "Remote Control Setup"
Step 3: Point your Samsung remote at the Sonos soundbar (aim at the front center)
Step 4: When prompted, press and hold the volume up button until the app confirms it received the signal
Step 5: Repeat for volume down
Step 6: Test volume control
IR learning works with any Samsung remote that outputs infrared - standard remotes, universal remotes, and some One Remote models.
Samsung One Remote Configuration
The Samsung One Remote uses Bluetooth to communicate with the TV and doesn't output IR by default. To control Sonos with a One Remote when using optical:
Navigate to Settings > General > External Device Manager > Set Universal Remote
Select "TV Audio" or "Home Theater System"
Follow the on-screen prompts to search for "Sonos"
Complete the setup wizard
This configures the One Remote to output IR signals for your Sonos.
For more details on Samsung remote functionality, including Samsung Bixby remote control and voice commands, check our remote guide. If your remote isn't pairing correctly, our guide on how to connect Samsung remote to TV addresses common issues.
Voice Control Options
With Sonos Voice Control, Alexa, or Google Assistant configured on your Arc, Arc Ultra, or Beam:
"Alexa, turn up the TV volume"
"Alexa, set TV volume to 30"
"Sonos, louder"
Voice commands require HDMI CEC connection and work when the Sonos is receiving TV audio.
Frequently Asked Questions
Can I connect any Sonos speaker to Samsung TV?
No. Only Sonos home theater products - Arc Ultra, Arc, Beam (Gen 2), and Ray - connect directly to Samsung TVs via HDMI ARC or optical. Standard Sonos speakers like Era 100, Era 300, and Move cannot be used as TV speakers. However, you can add these as surround speakers once you have a compatible soundbar as your primary TV audio device.
Does Sonos work with older Samsung TVs?
Yes. Sonos soundbars work with Samsung TVs dating back to at least 2015 using optical audio connections. The included optical adapter (with Arc, Arc Ultra, and Beam) or built-in optical port (on Ray) ensures compatibility. TVs from 2017 onward typically have HDMI ARC for better integration. For the best experience with pre-2017 Samsung TVs, use the optical connection and configure IR remote learning in the Sonos app.
Can I use Bluetooth to connect Sonos to Samsung TV?
Not recommended. Only Sonos Move and Roam support Bluetooth, and using Bluetooth for TV audio creates noticeable delay that makes watching video unwatchable. Even if your Samsung TV has Bluetooth audio output, the lag makes it unsuitable for anything except background music. Always use HDMI ARC, eARC, or optical for TV audio.
Will Sonos work with Samsung TV apps like Netflix and Disney+?
Yes. All audio from Samsung TV's built-in apps passes through to Sonos via HDMI ARC/eARC. However, some Samsung TVs don't output Dolby Atmos from the native Disney+ app - you'll need an external streaming device like Apple TV 4K or Fire TV Cube for Atmos on Disney+ with certain Samsung models. Netflix, Amazon Prime Video, and Apple TV+ generally work with full Atmos support on compatible Samsung TVs.
Can I control Sonos with Samsung SmartThings?
Limited integration exists. SmartThings can discover Sonos speakers for music playback control, but direct TV audio routing requires HDMI connection - SmartThings doesn't replace physical audio connections. For TV audio, you must use HDMI ARC or optical. Volume control through SmartThings routines is possible for music playback scenarios.
Can I use Sonos and Samsung TV speakers together?
No. Samsung's Q-Symphony feature - which allows simultaneous playback through TV speakers and a soundbar - only works with Samsung-branded soundbars. When using Sonos, you must disable TV speakers and output exclusively to Sonos via the Sound Output setting. However, you can expand your Sonos setup by adding a Sonos Sub and surround speakers (Era 100 or Era 300) for a complete home theater system.
Why does my Sonos show "TV" but no sound plays?
This indicates successful connection but incorrect audio routing. Check these settings: Sound Output must be "Receiver (HDMI)" not "TV Speaker." Digital Output Format should be "Auto" or "PCM." HDMI eARC Mode should be "Auto." If settings are correct, power cycle both devices by unplugging them for 2 minutes. This is one of the most common issues covered in Section 8.
Does Sonos support gaming on Samsung TV?
Yes. Sonos soundbars don't interfere with gaming features like VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), or 120Hz refresh rates. For the lowest audio latency while gaming, use HDMI eARC connection and ensure Game Mode is enabled on your Samsung TV. The slight processing delay in Sonos soundbars isn't noticeable for most gaming - competitive esports players might prefer headphones for absolute minimum latency.
Conclusion and Next Steps
Connecting your Sonos soundbar to your Samsung TV is straightforward once you know where Samsung hides its audio settings. The key steps are: use the HDMI ARC (or eARC) port, enable Anynet+ (HDMI-CEC), and set Sound Output to Receiver.
For most Samsung TV owners, the Beam Gen 2 offers the best balance of price, performance, and features. If you have a newer Samsung TV with eARC and want the ultimate audio experience, the Arc Ultra delivers dramatic improvement over TV speakers that justifies the premium price.
Quick Reference Summary
HDMI ARC connection: Connect to HDMI 3 (ARC), enable Anynet+, set Sound Output to Receiver
eARC for Dolby Atmos: Enable HDMI eARC Mode (Auto) and Digital Output (Pass-Through or Auto)
No sound? Check Sound Output setting, power cycle both devices, verify ARC port connection
Disconnecting? Look for CEC conflicts, check cable quality, update firmware
Expand Your System
Once your soundbar is working, consider expanding:
Add a Sonos Sub or Sub Mini for dramatically deeper bass
Add Era 100 or Era 300 as surrounds for true surround sound
Use Sonos Ace headphones for private listening with TV Audio Swap
