Hello everybody!

I've installed the latest alsa drivers (0.9.2). All the functions of the driver I need 
work, but the sound quality is poor. In Windows it sounds a lot better, although with 
ALSA it is much (somewhere like 2 to 4 times) louder (with the same mixer settings - 
wave and master to max, others to min). I've found that this loudness depends on the 
"VIA DXS" control, but not in realtime (e.g. when playing this control doesn't change 
anything, it has importance only when sound starts). Besides, if VIA DXS is set to 0, 
the playing doesn't start at all (e.g. the counter in xmms stays at 00:00).

What is the meaning of this control? I cannot find any information anywhere on it. And 
why the sound is so bad (it sounds like quantized at 8000Hz although /proc/asound says 
that channel is active and plays at 44KHz 16-bit)? Maybe its something with the mixer 
settings? It sounds like the sound from DAC is clipped somewhere *before* the 
amplifier (because master volume doesn't help with distortions).

Also maybe someone knows what the auxiliary controls that alsamixer shows are for? (3D 
control switch, surround, LFE etc). Some of them even cannot be changed from alsamixer 
at all (e.g. 3D control).
