This was already discussed in #gstreamer, thanks again for your great help! I
would like to put my final patches here for the records and for your
consideration whether to adopt it.
In Ubuntu we modified the current gstreamer sink structure a bit according to
https://wiki.ubuntu.com/GstreamerAudioBackend. In short: We want to use ALSA by
default, but only if dmix works (or, more precisely, if ALSA can play multiple
sounds at the same time). There is a (not too small) minority of cards where
dmix does not work; to retain mixing, we want to fallback to esound in these
* I added a new sink 'alsadmixsink' which only succeeds to open if the sound
device can be opened twice.
* The sink priorities were changed as follows: alsadmixsink > esdsink >
* esd is configured to not run by default, but is started when somebody
actually wants to talk to it (auto_spawn=1 in esound.conf)
Would you like to adopt this approach? I will attach the patches here.
