Hi. Well, it worked under Knoppix, so I'm sure it's just me.<snip>
I've just finished wiping and reinstalling Sid on a Vaio PCG-GRT170, which has worked before but got messed up with a Xwindows upgrade last week. Everything has come back except sound. mpg123 and xmms just hang until killed, and the following error is seen in dmesg:
i810_audio: drain_dac, dma timeout?
I've set the permissions on /dev/dsp and /dev/audio to 777, just to make sure that wouldn't be the problem. Also...
lsmod: i810_audio 24764 0 ac97_codec 13716 0 [i810_audio] soundcore 3940 2 [i810_audio]
lspci:
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0)
KDE InfoCenter shows only one DMA-Channel, "4 cascade".
When I cat sound.au > /dev/audio, I get a screech, so it seems that's completely out of time sync.
The Sound-HowTo talked about kernel modules, which doesn't seem to be the problem here.
Any suggestions? I expect it's a permissions problem that I just don't see, or the DMA that I just don't know how to make work.
1]
Boot off the Knoppix CDs; check what modules are installed. Install those modules once you're back in sid.
2] Make sure your user is in the "audio" group.
