IDT HD Kext Needed

I've got very choppy audio with my HP dv7 1130us.

Graphics are working great
airport just fine
memory.. Snow Leopard is doing great..

just need to get this audio going.

SNOW LEOPARD says the audio card is:

Intel High Definition Audio:

Device ID: 0x1002960F
Audio ID: 12
Available Devices:
Internal Microphone:
Connection: Internal
Speaker:
Connection: Internal
External Microphone:
Connection: 1/8-Inch Jack

and

Intel High Definition Audio:

Device ID: 0x103C30FC
Audio ID: 12
Available Devices:
Internal Microphone:

External Microphone:

However, in Windows 7 -- where, of course, it works perfectly .. the card is reported this way:

HDAUDIO\FUNC_01&VEN_111D&DEV_76B2&SUBSYS_103C30FC&REV_1003
HDAUDIO\FUNC_01&VEN_111D&DEV_76B2&SUBSYS_103C30FC
