[mythtv-users] sound buffers

I am having stutter problems with livetv.
Hardware: epia m9000, pvr-150, inbuilt sound card with alsa enabled
through the kernel, kernel is 2.6.11
Symptoms: every few seconds the tv freezes momentarily, there are a few
bluish artifacts on the screen, sound also freezes.
Investigations: Cannot give the exact error message at the moment as the system is at home and I am at work. However when I run mythfrontend -v
all (so as to get full diagnostics) I get lots of audio buffer error
Crawling through the list archives, along with the reference to audio in
the verbose output, leads me to believe this is an audio issue. However
i am not sure where to go from here. Options seem to be:
*use alsa instead of the oss/alsa emulation - but I have seen list posts
that claim the alsa support in myth is crap and to be avoided
*find some way of giving the sound driver (or the oss emulation layer)
more buffering space - how would I do this?
*try the independent alsa drivers instead of what is in the kernel
Any suggestions would be gratefully received.
As the epia board has no spare slots i don't really want to contemplate
another sound card.
