No sound. Command "mixer" say,

> mixer
Mixer rec      is currently set to   0:0

Only rec?

Need a main board of sis630/540 chipsets.

I think mismatch definition of value in /sys/dev/sound/pci/t4dwave.h

#define SPA_REG_GPIO 0x48  -->  0x4c
#define SPA_CDC_RWSTAT 0x00008000  -->  0x0000c000

After it changes, Sounds are OK. But, have a little noise and some error in dmesg.

Please see datasheet 630ds10a.pdf or 540ds10.pdf
