>Description:
dmesg | grep pcm
pcm0: <nVidia nForce2> port 0xb000-0xb0ff,0xb400-0xb47f mem 0xdc000000-0xdc000fff irq 20 at device 6.0 on pci0
pcm0: <C-Media Electronics CMI9739 AC97 Codec>

This is my module: snd_ich.ko

Problem: Then i modify some devices value with mixer, for example balance (rvol, lvol) , vol, it didn't make any effect. i can change volume only by pcm device.
