Matt, Thanks, no rush. I almost have the setup I need in place, most of it working with manual operation of mutes. I just need to code the socket interface now. The last piece, besides the socket interface, is to get pulse working properly in the living room media machine, which uses a digital spdif connection to the receiver. I almost have it working, few more kinks. Then I should be able to press a remote button in the room where audio is playing, and RTP through the rest of the house to all the other pulse enable computers :-) I wish I could figure out how to mute rtp-recv on the receive side. All I've been able to accomplish is muting in the send side, as you described in your scheme.
