What soundcard and which drivers do you use? I need this for the ALSA developers.

From /proc/asound/cards:

0 [AudioPCI       ]: ENS1371 - Ensoniq AudioPCI
                     Ensoniq AudioPCI ENS1371 at 0xdc00, irq 7

The driver is snd-ens1371, from the alsa-driver-1.0.3 package. The other ALSA
components are from the debian ALSA packages in the "unstable" distribution.

Have you tried upgrading to the latest version of alsalib and the alsa kernel
modules?

Yes, I've now upgraded the drivers, libs etc to 1.06a, the latest release
version. The result is the same.

Incidentally, the same MP3 plays fine with alsaplayer, so it seems to be related
to alsasink's usage of the ALSA libs, rather than the ALSA libs itself.

I have the same problem with gstreamer's alsasink. It looks like it has
something to do with alsa dmix plugin. Try renaming ~/.asoundrc file, or the
remove default decleration.

Yup, I have the same. So perhaps something in alsasink triggering a bug (or at
least an assert) in alsa, then.
