Well, I could even LIVE with analog if I had to, BUT the Audigy does not process ANY input lines, Toslink / Line-In / Mic-In. In fact, the volume control combines line-in and mic-in on one slider so you have no control there! I have mic-in being used for my voice activation mic so I don't want to put the XM on the line-in with it. I'm thinking maybe about just scrapping the Audigy and running my pc and xm into a dedicated eq/dsp unit (which is where the Alpine came into play). I'd lose the 5.1 for my DVD but I rarely use it anyway. It's just irritating to NOT be able to use my 5.1 amps/speakers as I wish.
