Sounds card issue with 10.5.6

[gmow]

Hi,

I just install my IPC 10.5.6 w/ Voodoo 9.5, after that there is not sound, I can see the id in system profile. It used to be working w/ 10.5.5, can anyone give me a hand.

Asrock Wolfdale1333-D667 R2.0 w/ ALC662 Sound card
EGVA 7600GTX 256md PCI-E video card (DVI)
SATA II 250 HDD
4G Ram

Also system profile show the video card is not support quartz extreme, is that anyway to enable it?

Thanks a lot,
GMow
