[Techtalk] Sound problem

I recently upgraded my Fedora Core 1 system to FC2.  It all went
pretty smoothly, and I have managed to sort out most of the problems
(such as the CDROM drive not working) myself.

But I have a problem with the sound card, which worked fine before.

When I boot the system, sound does not work.

Having run system-config-soundcard, which tells me that the module
snd-intel8x0 is being used, the sound is fine, and when I look at the
output of lsmod, a whole lot of inter-dependent sound modules are

I then reboot - and the sound does not work, although all the relevant
modules are still listed by lsmod.

When I run system-config-soundcard again, the sound works; the output
of lsmod is unchanged, though.

So, how do I get the sound to work from boot?

Incidentally, when I use 'play' at a command line, I get an error
message, 'application sox uses obsolete OSS audio interface'.

My /etc/modules.conf is

alias eth0 8139too
alias usb-controller usb-uhci
alias sound-slot-0 i810_audio
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 || :
alias ieee1394-controller ohci1394
alias char-major-195 nvidia
# Note: for use under 2.6, changes must also be made to modprobe.conf!

and my /etc/modprobe.conf is

# Note: for use under 2.4, changes must also be made to modules.conf!
alias eth0 8139too
alias usb-controller uhci-hcd
alias snd-card-0 snd-intel8x0
alias ieee1394-controller ohci1394
install sound-slot-0 /sbin/modprobe --first-time --ignore-install sound-slot-0 && { /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :; }
remove sound-slot-0 { /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :; } ; /sbin/modprobe -r --first-time --ignore-remove sound-slot-0
alias char-major-195* nvidia

The lines relating to sound modules possibly date from when I was running FC1.

FC1 uses a 2.4 kernel, and FC2 a 2.6 kernel.
