I've lost my sound after upgrading to hardy... In the beginning my sound card was still in the hardware driver, but now it's not there anymore (so not enabled either).

The only noise I get is some cracking, even though in vista it works (still have a dual boot, although never using it) so its related to ubuntu! Can anybody help me out?

Another problem is that I have awful video playback in full screen mode, but that's not that urgent! I just want to have sound for starters!
