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 | |
