m K o WTFK are you talking about ??? the sound feed from the composite cable supplied with the xbox is Analog and provides a stereo feed.The optical digital one provides dolby digital stereo or 5.1 discrete channels when hooked up to a suitable decoder...Try looking in the audio setup options on original xbox dash if dual booting with xbmc...
I didn't quite understand the original question, so i was just trying to point out that being analog/digital doesn't have generally anything to do with the amount of channels.
So my guess is that original question has something wrong in it.
Atleast i haven't seen any option in xbmc where you can choose between mono/stereo. Only analog/digital and with digital you can force stereo to all speakers.
Of course i could be wrong but this is just my opinion
