I type "su -" in a terminal window and become root. The "-" sets the
path correctly to find executables that ordinary users don't have in
the standard path because they don't always run successfully. They
need "root" privilege.
If I do a "which lspci" as an ordinary user I get no results. If I do
"whereis lspci" I get a result of /sbin/lspci. If, as an ordinary
user, I type in "/sbin/lspci" I get the same results as when I was
root. This is misleading. Do not be mislead by chance success.

This information is for illustration only.
I have an Intel 845G/GL mobo. This may not be the same as yours. 
There are two commands of interest to run. First is "/sbin/lspci" and
the second is "/sbin/lsmod". I use the full path here as additional
help. These should be in the path if the "su -" root login command was
used.

I am running SuSE 9.2. When I become "root" here is what I get when I
type "lspci":

The line---

"0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev02)"

--- tells me the type of sound card installed. The AC'97 is an Intel
onboard sound card.

The results of the "lsmod" command, for sound only, are---
snd_pcm_oss            57896  0
snd_mixer_oss          19200  1 snd_pcm_oss

soundcore               9056  1 snd
snd_page_alloc         10248  2 snd_intel8x0,snd_pcm

I don't know what all this means but something like this has to be
there for sound to work.

Good luck,

Robert
