AC '97 Sound not working, Dapper

I've been fighting to get my new laptop up and running. But i've got another problem.

Sadly, I find myself without working sound. There's some sort of an AC '97 mini PCI card, but I don't know what brand. eMAchines is the worst help imaginable. One of them said it was Realtek, one said GEneric, others have no idea. Ubuntu default loads "ATI IXP", which i'm not sure if it's correct or not. No sound works, but the volume control in the task bar is connected to -something-.

When I type "aplay -l", it shows "ATI IXP AC97". One of them is "Card:0 IXP [ATI IXP]", and the other is card 1: Moden [ATI IXP Modem]".

Is the Card 0 sound, or is aplay -l not picking up my card?

Edit: Also, if that is my card, it says "Subdevices: 0/1", which would lead me to beleive something's missing, which is why I can't get sound.

So first of all, Is that the sound card it's picking up? And Second, is that Subdevice what's screwing with me, and do you know where to find whatever I need to fix it?

Sound works fine on Windows (Bleh), so not a hardware problem.

We really need to know what laptop this is, and the output of lspci... for eg: mine says:
0000:00:02.6 Modem: Silicon Integrated Systems [SiS] AC'97 Modem Controller (rev a0)
0000:00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0)
... amongst other things.

You see the AC'97 thing is actually a modem. The soundcard is the other one.

However, the other way:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SI7012 [SiS SI7012], device 0: Intel ICH [SiS SI7012]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
... is less clear about what is present/meant.

When I have the modem driver installed, the modem also shows up here (as device 1), thus adding to confusion - especially if sound didn't actually go.

Enabling Alsa?

I "apt-get installed alsa*", does that enable it too?

Sorry, very new to this.

I can't get you the lcpci at the moment, but will as soon as I can!
