Well my sound workss with these crappy low-volume speakers. I was trying to use my normal PC speakers but they didn't work. And the sound only works in the front Headphone jack. I don't know what it is. I know it's an intel on-board card and it's not in the Hardware Profiler. It says none installed.

System
Vostro 200
Intel G33/G31 Chipset
Core 2 Duo 2.2GHz
1GB RAM

sorry I don't know much more

Edit

I used osx86tool and it gave me a choice of three audio drivers. I've tried all of them. No luck
This is now what the Profiler says under audio:

Intel High Definition Audio:

Device ID: 0x10280238
