My setup:
Playbar Gen 1, Sub Gen 1, 2 Sonos One speakers in my Great Room as Home Theater
New Amp powering 2 sets of old Analog Speakers
Issue: When I go from All Speakers playing music and I turn on my TV the Amp keeps playing the music. I beleive it should turn off when the TV Home Theater is invoked.
I believe this is currently working ‘as designed’. So this would need to perhaps go forward to Sonos as a feature request for their consideration. Sonos Staff will likely pick this up from your post here.
Normally auto-ungrouping the (playing) Sonos ‘rooms’ leaves the existing group playing the audio. You would currently need to pause/stop the group audio playback before switching on the TV.
If Sonos Staff do not respond here, then you can also send your feature request to Sonos by contacting the Staff at this link:
