After moving my TV I now connect from Sonos AMP to a 2019 Samsung The Frame via a fibre optic hybrid HDMI 2.0 18GBS cable. I cannot get any sound via the AMP (which is also connected to a Sonos Sub and 2 x Play:1s). Stuck with the TV’s speakers, which is a downer. Speakers all work for music.

The Sonos happily sets up the speakers via HDMI ARC, you get the success tone through the speakers every time. But the TV (while set to output via the Sonos) is silent. Every 3rd or 4th time you do the Sonos TV setup, you get TV sound through the speakers for 3 or 4 seconds…. until you get the success tone, after which it is back to silence! Any suggestions please? I’ve restarted and replugged all this 100 times now and am tearing my hair out.

Hi @JohnT-in-UK, thank you for reaching out to us, and welcome to the Sonos community. I appreciate you for bringing this concern to us as well as the steps that you did. Let me help you with this.

First I'd like to ask questions to isolate the issue so we can create a path towards resolution.

  1. When you select TV under Browse on the Sonos app, do you automatically get the audio on your Sonos Amp?
  2. Is TV Autoplay disabled in the Sonos app? What happens when you enable it or vice versa?
    • Settings > System > Home Theater Room] > TV Autoplay.
  3. Did you turn off the TV speakers from your TV during the setup? You can check it on your TV settings.
  4. Does your TV have an HDMI Arc port? What is the make and model of your TV?

Please submit a diagnostic report for us to check. Just include the confirmation number in your response so that we can look up the information. If you have any questions about this. We and the community are always here to help.
