Im just wondering if someone can clarify something regarding the hardware i have. i have cables marked with things like "mic- in, mic-bias, Return L, Return R, GND, VCC1, I+D, I-D, IGND" on my case I cant seem to see where to connect these on my motheboard!! I managed to connect all other hardware like hard drives and DVD roms. My apologies for the un-ubuntu-ness of this!
