No sound. Intel 82801BA/BAM AC '97. revisited.

[Nat Gross]

Ok, friends. It's time to sound off. (umm.. I mean sound ON. How long 
can I go without sound?)
I have followed various threads about this but I have never got sound 
with Linux on this machine, whose sound hardware is working under 
dualboot Windoz.
Hardware: Dell 4500 with 82801BA/BAM AC'97.
OS: FC3 2.6.10-1.770
I have followed the advice as far as muting headphone and line-jack 
sense, to no avail.
Also, when running the sound-detection applet, I have tried answering 
yes or no, with no results.

My /etc/modprobe.conf:
alias eth0 3c59x
alias eth1 dmfe
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && 
/usr/sbin/a lsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; 
/sbin/mo dprobe -r --ignore-remove snd-intel8x0
alias usb-controller uhci-hcd

--------------------------------------

Also, is it possible that by having an unused pda-usb cable plugged into 
the usb port, to be confusing this? Reason for this question is that the 
usb hardware also has Intel 82801BA/BAM, listed as the device.

Thank you all.
