I'm going to change things up here: there are things missing from my Windows sound options. The board maker, Asus, recommends SoundMax, but installing that creates some conflict, because eventually I'll get static when exiting a game back into MaLa, or when fast-forwarding a track in WMP. The pictures below show what I have. What I'm used to having on every other computer, and what I'd like to have, are 'line in' in the render section, and 'wave out' for the capture section.
Note: I have tried upgrading the driver, and it can't find a better one. I've also tried various versions of SoundMax with the same results. If I disable the HDaudio in the Device Manager, then I have no sound. Maybe there's something I could put in its place?...I haven't been able to find anything in my searches though.
