Though I've probably been more frustrated by Alsa, since I've actually
tried use it in the past, I'm less pessimistic about this. Have you ever
had a look at the Alsa API? I haven't yet met anyone who after reading
the docs and api could tell me how to actually use Alsa :) So, I'm holding
out hope for that it's ao_alsa that was buggy and not Alsa itself...

I've switched over to using ao_alsa as default now with alsa-lib 1.0.9
and ao_alsa CVS.

The only problems I've noticed is the buffer-underrun behavious, which
causes some cute artefacts. I know Clemens suggested increasing the
amount of audio buffered by MPlayer, but it seems a bit odd to me that
I get virtually no audible underruns with ao_oss..

It seems to have improved in the sense that it only fucks up itself and
not MPlayer anymore :) I sometimes get a crash on exit. It might be
one of the Alsa processes that segfault, because it doesn't seem to
get caught by MPlayer's sighandler... I'll blame the crashes on using
alsa-lib 1.0.9 with alsa 1.0.6 in kernel... I should probably upgrade
the kernel when I get the chance :)
