Mobo: Asus P5Q SE2


iPC 10.5.6 work like a charm except the sound. That does not work at all...

- In system profiler - "No Buildt -in Audio"
- The mobo have built -in sound card - "VIA VT1708S 8 -Channel High-Definition Audio CODEC"
- Somebody got this working??

- I've also inserted another sound card - "SupremeFX II Audio Card
ADI® AD1988B 8 -Channel High Definition Audio CODEC"
- The AD1988B Driver was on the driver list to iPC, but this does not work either...
- The "SupremeFX" card worked on Kaliway 10.5.2

What should I do?
