why did my soundcard stop working after i installed ubuntu? i'm doing a dual-boot situation and after installing it, my soundcard won't work in Windows XP or Ubuntu. wtf happened? it is detected, drivers installed/updated, no errors...it just doesn't play any sound from the computer. it'll play sound i make when i plug a mic into it though. would it have anything to do with the grub boot loader for ubuntu? i dunno wtf to do...it's obviously not a software issue, yet it doesn't have the symptoms of a hardware error. any halp?
