The audiohd driver does not support a codec from a nvidia video card.
The card:

pci bus 0x0003 cardnum 0x00 function 0x00: vendor 0x10de device 0x0a65
 NVIDIA Corporation GT218 [GeForce 210]
 CardVendor 0x1043 card 0x83e8 (ASUSTeK Computer Inc., Card unknown)

I have the only mixer device on it, but I don't know it works or not

I tried to modify this driver, but it is still hard for me.
It would be nice to get it working
