@Trent_Kaiser Always great to hear people are fining my code useful - thanks!
I’ve started looking at mute. I think it should be straight forward - will confirm…
Just for clarity the roon volume api I’m using is stateless - so the mute is a single mute toggle command (rather than mute / unmute)
Can you confirm that will be useful?
BTW if you haven’t already - take a look at this - which might help with your group sync. I used to have my studio monitors at home (they’re PMCs with digital inputs that use DSP to implement crossovers - and so introduce a delay - I adjusted this parameter which largely fixed the issue).
Lastly if you have other inputs - perhaps investigate RooPlay. This lets you play other inputs via roon. For some types of input - it can also automatically start the destination zone when it sees a signal.
