Hi,
On the HPC 6325 I'm currently using snd_hda_intel sometimes goes into an
endless loop in wich it plays the same chunk of sound (< 1 sec.) repeatedly
forever.
It helps to reload the snd_hda_intel module.
Greetings,
Rafael

Does position_fix help? See
Documentation/sound/alsa/ALSA-Configuration.txt.

Does this happen with disable_msi=1 or without?
Any relevant kernel messages?
The symptom indicates either an irq problem or a problem of
DMA position reading. The latter could be fixed via position_fix
module option as Lee suggested...

Without. Loading the module with disable_msi=1 apparently prevents it from
happening.

I haven't found any ...

I think that's an IRQ. [Andrew says MSI is busted in -rc6-mm1, so no wonder.]
