via82xx sound drivers patch

[1 1]

Good time of day!
I have tested my MB GA-7VAX and want to say you that you should use
VIA_DXS_ENABLE instead VIA_DXS_NO_VRA. On the maximum volume output level
with VIA_DXS_NO_VRA there is abnormal loud noise, and with VIA_DXS_ENABLE
there are much less noises. And I have detected unused code section.
With respect, Pantenkov Sergey.
Here is the patch.
