Sonos Beam Gen 2 (+Sub Mini + 2x Play 3 satellites) + Samsung The Frame (2019)
Occasionally (once a month / 6weeks or so) the Beam drops the TV signal coming via HDMI and it will not reconnect. The main manifestation is that in the Sonos App (Android), I can select TV as the input source, the app shows "TV", it connects and I can hear audio, then a couple of seconds later, with no input from me, the app shows "no audio source" and I no audio is heard from the TV. I can hit TV as many times as you like and the same behaviour is observed.
I have tried rebooting the entire system (the sockets are in the wall and not reachable without removing the TV so rebooting requires killing the power to the entire room from the main fuse board). There are no firmware updates for the TV, Audio output is set to PCM.
The Beam shows a solid white light but it flashes amber if I press the play/pause button.
Please help sort this one out...it's incredibly frustrating as I can't even revert to TV speakers as the TV is adamant that HDMI is available and won't allow me to select anything else for anything more than a few seconds
I almost forgot, this also happens if I plug my xbox into the TV, its fine until I disconnect the xbox then I loose sound through the Beam. In the past I didn't notice anything weird happening in the app and a system power cycle fixed it.
