I have a system that worked fine with the closed-source au8830
driver. I recently upgraded it to kernel 2.6.7 and have been
trying to get sound working again, without luck. The module
loads correctly, the card appears in /proc/asound, and programs
that access the sound card -- for instance, XMMS -- work fine.
The only problem is that no sound comes out of the speakers!
It's almost as if everything is muted, but the mixer settings are
maxed out (at least, the main volume and PCM are, as well as
anything else that looked vaguely like a playback channel),
dmesg doesn't show any errors, just the initialization message
from the driver:
Vortex: init.... <6>done.
