Hi,

dmix and dsnoop requires hw interrupts. Thats why they are bundled inside
alsa-lib and not in alsa-plugins. If you want to do dmx or dsnoop stuff, yo=
u
should definetly have a look at PulseAudio as Brad suggested. Not however
that PulseAudio require NON_BLOCKING alsa pcm. I am unsure about the sco
alsa plugin support for NON_BLOCKING mode. Maybe Brad could comment.

my 2cents,

--=20
