Hi Andrew, That's very interesting about the multi-stream playback option in your Realtek control panel, I don't see that option anywhere. I'm using a MacPro with a Reltek ALC885 and have headphone and line-out enabled. Regardless of what I do, the "Realtek HD Audio output" mixer is the only output mixer that gets listed. I have no idea why, perhaps it might have to do with differences in the way PC manufactures wire up and configure the ALC88x.
Anyway, I would like to have RAT given separate input and output device support added eventually.
