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?
