Hi
Is it possible to have two (or more) applications write to the same
soundcard at the same time with alsa?
Yes, using the dmix plugin provided by the alsa library. Use something like:
# aplay -D dmix:SLAVE=\"hw:0,0\",RATE=44100 x.wav
to play x.wav using aplay and the dmix plugin. You should be able
to start multiple aplays at the same time.
I don't know how good quality this produces, most people use JACK
(http://jackit.sf.net/) instead.
