no sound on alc-889

Hello all,

i try to unmute a box with a mcp79 ane alc-889.

the sound is working on another os, and playback
and recording are treated separately by os x, (10.7).

i tried different combinations according to the snd_hda man page,
but i cannot find a good one.

Pleease, have you some hints?

here is the config and pindump:

hdac0: <NVidia MCP79 High Definition Audio Controller> mem 0xd3480000-0xd3483fff irq 22 at device 8.0 on pci0

pci3: <network> at device 0.0 (no driver attached)
