after some troubles I've get a way to fix ''native'' audio support on my asrock alivenf7g.
It doesn't support voodoohda and snow apple hda so I've try to install applehda from 10.5.7 patched with taruga's hdaPatcher, a custom dummy kext containing pinconfig and device-id injetion and device HDEF under ''Name (_ADR, 0x00070000)'' in my dsdt.
[codebox]Device (HDEF)
Name (_ADR, 0x00070000)
Method (_DSM, 4, NotSerialized)
Store (Package (0x08)
Buffer (0x04)
0x0C, 0x00, 0x00, 0x00
Buffer (0x04)
0x62, 0x06, 0xEC, 0x10
Buffer (0x0F)
"Realtek ALC662"
Buffer (Zero) {}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)

et voilà, audio works 2in & 2out. perfect!
the strange thing is that the audio bridge 00070000 is different from standard 001B0000 so I believe that snow hda won't recognize driver

Another way to get only output working is using leopard applehda (above) and appleazaliaAudio.kext Attached File  AppleAzaliaAudio.kext.zip   82.99KB   91 downloads no dsdt patch needed

Thanks so much for this, the second kext works perfectly on 10.6.8 with an ASRock G41M-S3.
