Hello all, I just discovered PulseAudio about 2 weeks ago and was struck by how applicable it could be in creating a whole home audio solution where each room can subscribe to the same or a different audio stream as another room. To create this I setup 4 mpd instances, each talking to a different rtp-send module. Then on the playback side there are 4 rtp-recv modules that can connect to each of the multicast streams. I have all of this functioning and have written a small python app to configure the modules via the unix socket cli connection. All of this is implemented on one machine so I have the rtp-send modules looping back the data. Now for my question: This implementation obviously spews a lot of multicast traffic onto my network. I didn't think this would be a problem, but my router/ap/switch seems to crap out when it gets hammered with all the traffic. Is there any way that I can specify which interface pulesaudio sends its multicast packets on? Or even more ideally, can I disable all outgoing multicast traffic and just have the local loopback happening? I have attempted to configure the kernel routing tables on my ubuntu (7.10) install, but with no change. I still see all the multicast packets going out the interface (using ethereal on another machine to check). I have pulseaudio version 0.9.9 that I compiled myself. Thank you to the authors of this awesome software package! Matt P.S. If anyone is interested in my little whole home audio project I am perfectly happy to share my rather hackish python/php code and maybe get a little help.
