Hello! Still working on my multi-zone setup. The goal is to have multiple instances of MPD playing, and being able to be routed to 0 or more zones simultaneously. Each player is connected to a unique sink created with module-combine, with each of these combined sinks including *all* of the physical sinks. Something like this: #Physical sinks for actual hardware load-module module-alsa-sink device=hw:1,0 sink_name=zone1 load-module module-alsa-sink device=hw:2,0 sink_name=zone2 load-module module-alsa-sink device=hw:3,0 sink_name=zone3 #Module-combine sinks for handling each MPD load-module module-combine sink_name=mpdplayer1 slaves=zone1,zone2,zone3 load-module module-combine sink_name=mpdplayer2 slaves=zone1,zone2,zone3 load-module module-combine sink_name=mpdplayer3 slaves=zone1,zone2,zone3 For now, I have a single instance of MPD playing through sink mpdplayer1. When I start up MPD and play something, I get audio out of all three sinks. So far, so good. Now, though, I would like to mute the sound in all but one of the zones. I can't simply do something like: set-sink-mute zone2 set-sink-mute zone3 Because that would mute the outputs for those zones, and they might be (and likely are) playing music from one of the other MPD sessions. What I want to do is tell the module-combined sink (mpdplayer1) to only send audio to one of the sinks and to mute the output to the other two sinks. Is this possible? I cant seem to find a way to interact with the individual channels within a module-combine... Tim Massey
