just got my sound working. when i loaded it i had no sound. if anyone decides to check it out and has ati hdmi sound. be sure to go to additional drivers and activate the ati driver. this installed hdmi sound card as well built onto the card. thing crushes windows 8 and was the only hiccup i had while installing ubuntu 12. desktop looks like osx but slicker with my TR PS2 backround. but sound seems to be a big problem getting it to work in ubuntu 12 so thought i'd throw this out there for the nerds who are running amd bulldozers wanting to check it out. i'll probably video my desktop once i turn on compiz. haven't activated 3d desktop yet
