How Do I Fix My Sonos Beam Not Playing TV Audio?
- Incorrect TV audio output settings
- Loose or incorrect HDMI ARC connection
- TV internal speaker enabled
Problem Description
Your Sonos Beam is connected to your TV via HDMI ARC or optical but produces no sound, plays audio only occasionally, or cuts out during playback. The TV may show volume changes responding to the Sonos app yet no audio comes through. Sonos Beam audio failures are caused primarily by incorrect TV audio output settings, CEC conflicts, or an HDMI ARC handshake that has stopped initializing after a TV firmware update.
Symptoms
- No sound from Sonos Beam when TV is on
- TV speakers are playing instead of Beam
- Sonos app shows "No TV Signal"
- Audio cuts out intermittently
- Happens after TV power cycle
- Music playback on Beam works fine
Recognize these? Here's what usually causes it.
Common Causes
- Incorrect TV audio output settings
- Loose or incorrect HDMI ARC connection
- TV internal speaker enabled
- Outdated TV or Sonos firmware
- HDMI cable issues
- CEC (Consumer Electronics Control) conflicts
Most fixes happen in the first 3 steps.
Before making changes to your TV"s settings, it"s a good idea to note down the current settings so you can revert them if needed. Consult your TV"s manual for specific menu navigation.

Step-by-Step Solution
Adjust TV Audio Output Settings
Access your TV"s audio settings menu. Ensure the audio output is set to "External Speakers" or "HDMI ARC" and that the digital audio output format is set to "Bitstream" or "Dolby Digital" (not PCM or Stereo). This ensures the TV sends the audio signal correctly to the Sonos Beam.

Ensure your Sonos Beam is connected to your TV"s dedicated HDMI ARC (Audio Return Channel) or eARC port. This port is usually labeled and is essential for transmitting audio from the TV to the soundbar. Disconnect and reconnect the HDMI cable firmly at both the TV and the Beam.
Disable TV Internal Speakers
Many TVs automatically switch to external speakers when an HDMI ARC device is connected, but sometimes the internal speakers remain active or interfere. In your TV"s audio settings, explicitly disable the internal TV speakers to ensure all audio is routed to the Sonos Beam.
Update TV and Sonos Firmware
Ensure both your TV and your Sonos Beam have the latest firmware. Outdated firmware on either device can cause compatibility issues with HDMI ARC and audio playback. Check your TV"s settings for software updates and your Sonos app (Settings > System > System Updates) for Beam firmware.
Troubleshoot CEC (Consumer Electronics Control) Issues
CEC allows devices to control each other over HDMI. Sometimes, CEC can cause conflicts. Try disabling CEC (often called "HDMI-CEC", "Anynet+", "Bravia Sync", "SimpLink", etc.) in your TV"s settings, then re-enable it. Or, try disabling it entirely and using the Sonos app for volume control.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
If your TV does not have an HDMI ARC port, you can use the included Optical Audio Adapter to connect the Beam to your TV"s optical digital audio output. However, this will not support advanced audio formats like Dolby Atmos.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
