I am using the optical in on my Audigy Zs notebook, but for some reason when i try to play Xm in Mediaengine it will mute the Optical In line.

After further research i noticed that when anyone makes any adjustment to the Mic in or Line in it will mute the Optical In since they share the same port. Only 1 of the three can be used at once. Has anybody figured out how to stop this auto muting?
