I just got my new PC and wanted to hook up my Tritton AX 720's through optical cable for surround sound. I receive audio output but as far as input goes there is none for my microphone. Is it possible to use my headset's microphone through an optical cable? Any advice would be greatly appreciated.
 


That makes sense, so now I am using standard line in and line out for my headset. However, when I mute my microphone the audio from the line out is going through the line in. I cannot figure out why this is occurring, are there any possible fixes for this?
