I just modded my aao with a 8gb cf, put ubuntu on it, it worked fine. So I formatted and put windows xp pro on it, and I have no sound. Under control panel it says no device. I installed the drivers twice and still nothing. I have something in device manager with a yellow mark on it about pci device, so I tried to manually search for the driver through that, but nothing. I get those beeps from the pc speaker, but nothing else. I tried driver 5.10.0.5628 that is listed on this site.
