i have the same sound-chip.
take a look at the modules that are loaded.

here, the output of " $lsmod |grep snd " gives :

snd_pcm_oss 47912 0
snd_mixer_oss 17344 1 snd_pcm_oss
snd_via82xx 21828 2
snd_ac97_codec 68496 1 snd_via82xx
snd_pcm 81288 2 snd_pcm_oss,snd_via82xx
snd_timer 20036 1 snd_pcm
snd_page_alloc 7560 2 snd_via82xx,snd_pcm
snd_mpu401_uart 5824 1 snd_via82xx
snd_rawmidi 19300 1 snd_mpu401_uart
snd_seq_device 6408 1 snd_rawmidi
snd 45668 13
snd_pcm_oss,snd_mixer_oss,snd_via82xx,snd_ac97_cod ec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,s nd_seq_device
soundcore 6880 1 snd

and it works here...

Default Re: snd-via82xx; Slack10, low sound, alsamixer maxed,

You look at your PCI chip(s). Open up your case and look at the
set of chips on the board. (If it is onboard sound). Write down
the numbers of the large chips. You may recognize the chip in the
table in the Sound-HOWTO or Sound-playing-HOWTO If you google your board
probably the manufacturer says it is AC97 PCI/codec or something
similar. Several drivers use that, so learn more. It could be
via82cxxx_audio or other. OSS drivers will drive most sound cards and
on boards. AlSA is not always necesary.

When a sound card is not run by a mixer it is muted. You have to turn
off muting. You can sometimes do that from amixer with the unmute
command. KDE mixer controls should unmute the card. There are several
controls. Check them all. Gnome is a bit flakier.

modprobe can give info about driver options. (modprobe -p)? man modprobe
for more info.

It pays to recompile the kernel and work your way through sound modules.
Read carefully. Install sound support and the cards as modules. You may
have to explicitly load the card driver with modprobe. It may not
automatically load with kmod. cat /proc/modules to see if it loaded.

Maybe it's no help for you, but I'm using alsa for sound with the same
module
(snd-via82xx) and is working great. First time I tried the oss driver
but that
didn't work. After installing alsa I had to raise pcm volume to
something
between 50% and 100% because the master volume wasn't enough. So now
it's working
ok without any parameters.
Sound card: SoundMax (onboard)
Slackware version: 10.0

Thanks to everyone who made a submission. After taking what you all had
said, and doing a little more research I was able to get the sound to
respond (also the connection is cheap, needed to be seated just right, just
a hair off of fully in).

And for the member discussion: What I really meant was members of the
registared Juntas Clan, a specialized group of 'Q' monks who have taken a
vow of silence, preferring to communicate thru lettuce inscription or
typing (which ever is easier at that time).

Thanks,
Chris

Here it works too and I have exactly the same modules. Make sure you have
these modules, otherwise you'll have to rebuild the kernel or maybe only
the modules. You'll have to run "alsamixer" to adapt the volume and
"alsacfg store" both as root.
If you want sound while browsing using thunderbird you'll have to start
firefox with "/opt/kde/bin/artsdsp /directory/where/you/installed/firefox"
