[2.4.20] via82cxxx goes postal and locks system, no full duplex(?)

I get a lot of errors, sometimes it locks the system, sometimes it does
not.
one of them is as follows:
via_audio: ignoring drain playback error -11
via_audio: ignoring drain playback error -11
via_audio: ignoring drain playback error -11

now this causes no problem because when its happening I hear no change
in the audio, so I basically ignored this error.
I started getting this error, and after this error is logged the box
sometimes deadlocks:

Assertion failed! chan->is_active ==
sg_active(chan->iobase),via82cxxx_audio.c,via_chan_maybe_start,line=1198

this error repeats several times and is the same.
ive got a 50/50 chance of deadlocking at this point.

this is the second failure in getting a via board to work.
I also have a kt400/8235 machine that has no driver, so im really
screwed :(
2 machines both with via sound, both act crazy.
I also have no full duplex, at least I cant find out if this is the
case.
I can play a game, and the game only. if i run something like teamspeak,
or an mp3 player the seconf application will crash, or lock up.
this often triggers the errors above.
I understand this is a full duplex issue.
as long as I do not load 2 apps that use sound, im okay.
I have had to rid KDE of its sound daemon to avoid crashing.
I hope someone has an idea.
