Windows 7: sennheiser mm200, stereo with microphone

i have windows 7 and i want to be able to play starcraft 2, listen to some low background music or game play in stereo while having the microphone active at the same time so i can talk with my friends i'm playing with.


it seems right now i can have either or when i know i should be able to have both at once since i've somehow managed to to this before.




in the control panel sound i have 2 bluetooth profiles for audio output one in stereo and one in mono, if i use the stereo i hear everything fine but the mic doesn't work. If i instead use "mono" i hear nothing but the occasional crackling but the mic works. tho testing the audio setting in skype i know hear the sound and the mic works there too.

How do i get stereo sound from, say winamp or starcraft and microphone active at the same time? the skype phone call with my friends during game play doesn't need to be in stereo but i still want to be able to hear them and talk.
