Sound card... Nonexistent?

[SirBen]

I'm running Ubuntu 11.04 on an Inspiron 9200.

I got the laptop used, from a good friend of mine, when Windows was flashing constant BSoD at them, so I messed about with XP for a bit, and my sound card didn't work then. When I put 11.04 on it, it still doesn't work, though I guess I shouldn't be surprised.

I am surprised, however, that running 'sudo lshw' in the terminal turns up nothing that even resembles a sound card, but when I was changing some settings in my BIOS, it did say one existed, specifically a Sigmatel 9750.

Any ideas? I've been dreading pulling this apart, as I have only worked on desktops in the past and have no idea how to do this safely. I also cannot find a component map of my motherboard anywhere, and I've been trying to google it up for about a week now.

Thanks in advance for any help.

Most likely the sound card is dead. If it did not work with either XP nor Ubuntu that is the most likely case. You can google this: dell dimension 9200 sound card and get check out the sites. I have no idea what sites are good and what are not though.
