It would be good to explicitly state the audio input priority

My Sonos ARC is connected to a Sony TV with a HDMI cable with ARC.  It is also configured as an Alexa.

Sometimes I want the TV to be showing something, but the audio to be separate from the show. Right now it seems to “partially” work.  If I start playing from an Echo (with the Sonos set as the default Alexa speaker) the TV audio is silenced, but the Alexa audio is unheard.  Turning off the Alexa Audio (stop) does not restore the TV audio till I change something on the TV side, and even then, it seems to come back with the Volume at zero.

 It would be great if I could explicitly state that audio on the Alexa side takes preference in all cases.

Sonos essentially follows the last command it’s received to play audio.  So when you give an alexa voice command to play audio, it will always stop whatever it’s doing and play that audio (or it should, sounds like there might be an issue with your system)  Likewise, if you went it to the Sonos app and told it to play a different streaming service, or TV audio, it would do that, regardless of what it’s currently playing.

Perhaps the exception to this is that you can set your Arc to autoplay whenever it receives an audio signal (from no signal at all) through the HDMI cable.  It will automatically stop what it’s playing and start playing TV audio.  Note that this doesn’t mean that if you start to play something else while TV audio was playing, it will ignore your command and keep playing audio.  The trigger only happens when the TV audio signal goes from absent to present, effectively.

This sounds like it meets your need for input priority, but there seem to be other issues going on with your setup.  When you make a command to play music via Alexa, the music should play on your Arc.  Not sure what you mean by ‘Alexa audio is unheard’.  When Alexa music stops, it will not automatically revert to TV audio (although muting and unmuting TV audio can trigger the auto play).  I’m not sure if that’s happening as expected as I don’t know what “I change something on the TV side” is referring to.
