I'm using the ALSA 1.0rc2 drivers along with MythTV, however I've run into two sound problems:
First, when I play a DVD, the sound (and video) tend to 'jump' and sound 'garbled'. I don't run into this problem when I use the kernel driver for 2.4.23 (via82cxxx_audio), that is, the sound and video are perfectly synced and don't make the popping/jumping noises.
Second, when playing back TV recorded with MythTV, the sound/video have the same garbled/out-of-sync problem after ~10 minutes of playback. I haven't been able to reproduce/refute this issue with the 2.4 kernel driver, b/c MythTV needs full-duplex, and I don't think that the kernel driver likes that ;). If I stop and restart the playback, the problem disappears for ~10 minutes.
The only suggestion that I've found from the lists in the past is trying to use the dxs_support option with the snd-via82xx driver. I've tried both dxs_support=2 and =3, but neither has worked. The soundcard is on the motherboard (ECS K7VTA3 version 8.0).
Sadly I'm not offering help here.
I have probably a related problem. Using the same driver on a K7VT2 MB and the linux-2.6.0-test11 kernel.
Using XMMS version 1.2.8 with the libOSS.so driver I get a garble/speed up at exactly 19 seconds which last perhaps 2-3 seconds.
Using XMMS with the libALSA.so driver. I get persistent clicks through-out the MP3 track.
Anyone else got an idea of this is caused by?

MSDOS is not dead, it just smells that way.
