Audio problem on Dell Dimension 4600

I am working on a solution for the onboard audio on this PC running RH8.0.
The Intel site suggests for RH8.0 linux and this motherboard (Intel D865PESO) 
to use the driver, ADI Integrated Audio Driver 
[alsa_driver_0.9.1adi_rev5.tar.gz]. This driver installed OK, except that the 
last 2 lines of the recommended addition to the modules.conf file caused 
problems and had to be deleted (see below).

The sound modules load but do not work - not one note. For example, if I try 
to play an mp3, I get the message

"couldn't open  audio; Please check that

1. you have the correct output plugin selected
2. no other program is blocking the soundcard
3 your soundcard is configured correctly

The KDE utility system settings/soundcard detection says:
Vendor: unknown vendor
Model: generic snd-intel8x0 device
Module: snd-intel8x0
"test" produces nothing; an audio cd likewise.

Dell has informed me "the 1980 audio solution uses the AC97 2.2 compliant 
digital bus from the ICH5 and the Analog Devices ADI1980 AC97 CODEC."

However I have good evidence the motherboard is the D865PESO model, and the 
Intel website shows this model uses the Analog Devices AD1985 codec, not 1980.

The lines added to the modules.conf file are:
# ALSA native device support
alias char-major-116 snd
options snd major=116 cards_limit=1
alias snd-card-0 snd-intel8x0

# OSS/Free setup
alias char-major-14 soundcore
alias sound-slot-0 snd-intel8x0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

The 2 extra lines that caused a heap of error messages during boot (including 
failure to mount a dos partition), and I removed, were:
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L
>/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 
2>&1 || :

Any suggestions for further action would be much appreciated.
