@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). > [@Sound out of sync \[Solved: Adjust Zone Grouping Delay\]](https://community.roonlabs.com/t/sound-out-of-sync-solved-adjust-zone-grouping-delay/167847/2): > > You can then adjust the Zone grouping delay on the other to get them closer. This is all in the advances settings for each device. 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. --- _[View the full topic](https://community.roonlabs.com/t/roon-with-home-assistant-and-matter/256605)._
