May 16, 2015 at 10:15 comment added Christi Nope. If you manage to get it working, do post. As far as I'm aware the configs above should do the right thing if the actual code works.
May 11, 2015 at 13:05 comment added Doug Edey The last comments from this is from 2014, did you reinvestigate now (since it's been a year)? to see if you can get this working?

May 17, 2014 at 20:17 comment added Christi As I mentioned above, I did get Pulseaudio working. It works fine on each individual device, and then fails when you attempt to create a stream to multiple outputs at once. I believe a lack of memory mapping in the RasPi I2S driver to be the culprit, but further debugging would essentially involve learning the internal structure of ALSA and/or Pulseaudio, which I do not have the time or inclination to do.
May 17, 2014 at 16:32 comment added earthmeLon I can only suggest trying to get pulseaudio working, as it is capable of doing exactly what you wish to do (including extending to other soundcards on the network).

May 7, 2014 at 12:46 comment added Christi After further investigation (and a second attempt with pulseaudio), I think that the problem is that this kind of feature requires shared access to the sound card memory and/or mmap support. The RasPi I2S driver doesn't support this. I can't really confirm this, as there is no particularly useful debugging info either from ALSA or PulseAudio - in general, everything works until you try to engage multiple sound sources. I am uncertain whether this will be fixed in the RasPi kernels or not, but trying to fix it would time more time than I'm willing to invest.

May 2, 2014 at 18:50 comment added Christi I have looked into pulseaudio. My experience was that it basically didn't work.
May 2, 2014 at 18:49 comment added Gerben I think you should look into pulseaudio. But I might be wrong here
