I am trying to purchase a new motherboard. I was recommended:

ASRock Z68 Extreme3 Gen3

But not sure what sort of Linux support it has. Anyone have one of these?

I also noticed under "features" (ugh):

7.1 CH HD Audio with Content Protection (Realtek ALC892 Audio Codec), Supports THX TruStudio

Does anyone know wtf "Content Protection" means for audio? Does it mean it can only stream M$(C)(R)(tm) brand audio files that you have to pay 10 cents per listen?

Basically, will I be able to use 7.1 sound on Ubuntu with this mobo?
