[alsa-devel] bug

[Mattia Bertoni]

finally I can report a bug which I encountered some time ago; I send you 
the important part of the entire log, which is to much big to be posted:

Jun 15 18:18:00 arch-dekstop pulseaudio[776]: [alsa-sink-Intel ICH] 
alsa-util.c: snd_pcm_avail() returned a value that is exceptionally 
large: 420736 bytes (2191 ms).
Jun 15 18:18:00 arch-dekstop pulseaudio[776]: [alsa-sink-Intel ICH] 
alsa-util.c: Most likely this is a bug in the ALSA driver 
'snd_intel8x0'. Please report this issue to the ALSA developers.
