Trying to get Alsa setup on a Knoppix HD Install from the 4.0.1 DVD (Kernel 2.6.12)

lspci -v shows the following:
0000:00:1b.0 0403: Intel Corp. 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)
Subsystem: Hewlett-Packard Company: Unknown device 2a09
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at bfe38000 (64-bit, non-prefetchable) [size=16K]
Capabilities: [50] Power Management version 2
Capabilities: [60] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable-
Capabilities: [70] #10 [0091]

Any idea what I need to modprobe or otherwise configure to get this to work?

TIA,
Ewan
