Subjectvia82cxxx_audio problems
I'm having a little problem with an via82cxxx_audio sound
(on-)board, someone already saw this?

kernel 2.4.14 + 1.1.19 version of via82cxxx_audio driver:

With rapid fast-forward in mplayer, The sound just mutes itself and
mplayer just crawls down to 1-2 frames per second. Looking at
/var/log/messages Ive got:

Nov 12 21:51:36 stratus kernel: via_audio: ignoring drain playback error -11
Nov 12 21:52:08 stratus last message repeated 2 times
Nov 12 21:52:19 stratus kernel: via_audio: ignoring drain playback error -11
Nov 12 21:55:32 stratus kernel: Assertion failed! chan->is_active == sg_active(chan->iobase),via82cxxx_audio.c,via_chan_maybe_start,line=1206
Nov 12 21:55:47 stratus last message repeated 8 times

these "drain playback error" are generally harmless, I get it all
times that artsd 'gets' or 'releases' /dev/dsp (I configured it to
release /dev/dsp before 10s of inactivity).

'Assertion failed' is the culprit (or the simptom of it).

After that all tryes to use sound got no results.
