Correction. I am using App-->Pulse-->ALSA-->Jack-->ALSA
for all non-live-music sound :-) It gets a little complicated
sometimes, but the results are very good. The idea is that Pulse and
Jack handle multiple streams and stream cutoff extremely well, but ALSA
often does not; so we rely on Pulse and Jack to do what they do well,
and rely on ALSA more as glue to the hardware and between other audio
pieces, than as a standalone audio system.
J.E.B.
Sounds like an ALSA-mixer plugin problem to me. The theory goes that
when multiple attempts to output sound to an ALSA sound card are made
at the same time, ALSA is supposed to recognize whether or not the
sound card can mix the streams in hardware, and if not, ALSA is
supposed to introduce its own software stream mixer automatically. But
I have multiple reports that it often just doesn't happen. And because
audio applications don't always terminate their output cleanly,
multiple sequential attempts at playing a track can be interpreted as
being quasi-simultaneous; and if the mixing ability doesn't work, you
get what you're seeing, something crashes in ALSA and sound dies on the
box.
I fixed the below symptoms on two boxes of mine, using alphanumeric
sound card
names plus using PulseAudio to handle the multistream issue, as an
entryway to ALSA. I have Jack involved too, which means I am using
App-->ALSA-->Jack-->ALSA for all non-live-music sound (see
here). If you
don't need Jack, I suspect that if you convert any vanilla distro which
uses Pulse by default to use alphanumeric names, and then make sure
that all of your audio apps go to Pulse (except Audacious, that's still
a problem apparently) using an .asoundrc (see attached), you should be
fine. Otherwise, I would use the AAJA method linked above.

Hello everyone,
I'm using Debian Lenny and since I exchanged my mainboard and relating
components some time ago I encounter the following problem:
When I listening to some music (using Amarok-1.4.10 or herrie) playback stops
somewhere at a radnom time, when maybe 3-5 (differs randomly) tracks have
been played. herrie can't be terminated in regular way after a playback-stop,
using Amarok I can simply restart playback and everything is alright.
I think this is a problem concerning ALSA, because if it happens using herrie,
everything will be alright after running 'alsaconf'.
Does anyone have a hunch, whtat's wrong here and how to fix it?
Thank you. Regards
->Lukas
