Summary: only mono sound available on via82xx
Description:
Only get mono sound with alsa. This is shown by the fact that I cannot
change the master stereo volume e.g. in alsamixer, only mute or unmute
it.

Tried with kernels 2.6.12, 2.6.13, both compiled into the kernel or as
modules. Also happens with the drivers from the alsa homepage
(1.0.10_rc1). Tried live CD's from Gentoo (2.6.12 kernel) and from Knoppix
(2.6.11). dxs_support 1-5 and ac97_quirk parameters didn't solve the
problem. Neither did changing volume / muting and unmuting a combination
of controls in alsamixer.

However: A Ubuntu Live CD (Kernel 2.6.10) gives me normal stereo sound.

I just wanted to add that in fact I can hear sound and it is stereo, I just
cannot change the master stereo volume, just the PCM one.

Any improvement in later releases?
