I've got an Asus A7V8X-X MB which seems to have a VIA 8233 AC97
sound chip based on the output of lspci:

00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio 
Controller (rev 50)
        Subsystem: Asustek Computer, Inc.: Unknown device 80a1
        Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV-VGASnoop- ParErr- Step ping- 
SERR- FastB2B-
        Status: Cap+ 66Mhz- UDF- FastB2B- ParErr-DEVSEL=medium >TAbort- <TAbort - 
<MAbort- >SERR- <PERR-
        Interrupt: pin C routed to IRQ 3
        Region 0: I/O ports at e000 [size=256]
        Capabilities: [c0] Power Management version 2
                Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot 
-,D3cold-)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-

        I'm running RedHat 9.0 and the default OSS drivers do not work
with the onboard sound. I've install alsa-driver-0.9.3c, but I can not
get any sound out of the hardware. I've set the mixer levels and all
that and I have a dual-boot with Win2K where the sound works, so I know
that the hardware is functional. The only indication that something
might be wrong is the printk errors when the snd-via82xx module loads:

PCI: Found IRQ 4 for device 00:11.5
IRQ routing conflict for 00:11.5, have irq 3, want irq 4
PCI: Setting latency timer of device 00:11.5 to 64
ALSA ../alsa-kernel/pci/via82xx.c:499: codec_valid: codec 0 is not valid
[0xfe0000]

        I get maybe 15 or 20 instances of this error. I've tried mapping
interrupts in the BIOS, but no combination of settings seems to change
the "codec_valid" message. 

Thanks for any suggestions...
