Issue with sonos amp and Samsung the Frame

My Samsung Frame TV is suddenly no longer able to play audio through my Sonos AMP connected via HDMI ARC. It had worked largely without issue for 3 years.

I have a Samsung Frame TV (2022) with the following details:

  • Model Code: QN65LS03BAUXXN

I have a Sonos AMP with this info:

  • Sonos OS: S2
  • Version: 17.7

I have the Sonos AMP connected to the Samsung TV’s HDMI ARC port (HDMI 3) and have been able to play audio from the TV and a connected Apple TV device without issue for almost 3 years. Today the TV is no longer recognizing the Sonos AMP as an audio output option and I am limited to the built-in TV Speakers.

From the Sonos App on my phone, if I go to the AMP and click on TV Setup, then click Continue, then click Connected to ARC, then click Test connection, I get an error of “TV speakers not connected.” 

Also, the Sonos AMP itself still plays audio just fine from other sources like music via Spotify.

On the Samsung TV itself, I have not changed any connections or settings. The HDMI-eARC Mode = Auto, and under the External Device Manager I have Anynet+ (HDMI-CEC) enabled.

Troubleshooting Steps Attempted without success:

  • Unplugged the Sonos AMP and waited to reboot it
  • Unplugged the HDMI cable from the Sonos AMP side
  • Changes the HDMI ARC cable to a new one
  • Toggle the Samsung TV’s settings for HDMI-eARC Mode and Anynet+
  • Attempted the TV Setup in the Sonos Mobile App again
  • Reached out to Sonos Support who cannot find the solution to my problem

I have seen several other similar posts that are a few years old with similar issues but have not been able to figure out the root cause or a fix. The post titled “Sonos Arc Samsung Frame TV eARC not working” seems very similar but again I don’t understand why this is happening today and how to fix it.

If this is a known issue, is there some patch to fix this issue?

Sending the diagnostic queues it up in the Sonos support computer but it won't be looked at by a human until you call Sonos and ask the support folks to pull it off the queue and look at it.

I don’t see it listed, but did you unplug the TV from power for two minutes as well? I’d probably, after it reboots, check it for updates as well. 
 

All of my Sonos devices are on a later build (version 18), although I don’t own an Amp. Have you checked your Sonos for updates, as well?

I have tried to unplug it for a while but it did not solve the problem 

You are right, my Sonos amp did not have the last update. I did it but the problem is still here

Interesting. When you reached out to Sonos support, did you submit a system diagnostic within 10 minutes of experiencing this problem? And perhaps more importantly, since this doesn’t seem to be a prevalent issue across many TVs, did you contact  Samsung’s support?

This is usually a CEC/ARC handshake glitch between the Frame and the Amp. Try power-cycling both fully (unplug TV + One Connect box + Amp for a few minutes), then reconnect with only the Amp on HDMI 3 and re-run TV Setup — this often forces the ARC device to be re-detected. If not, it’s likely a Samsung firmware update broke ARC, which unfortunately is a common issue with Frame models.

Yes I have contacted both. Samsung said it the cable was the issue but it is not. And I did send the diagnostic to Sonos as well

I don’t have a Frame TV nearby to try this, but I suspect that a CEC Blocker will help this issue, unfortunately it may create other issues.
