I have a SGS2 ATT and use bluesoleil 8. It works out fine. I just checked the A2dp service in bluesoleil and selected the audio output in my android to bluetooth, then it all worked. All the system audio is routed to my pc.
There is not so many chances with options other than bluetooth, since android os doesn't allow audio routing. There are a lot of solutions for playing music files stored in android on pc using wifi or DLNA. But if you are trying to play the system sound of android on pc, bluetooth seems like the only possible way unless you root your phone and hack audiofliner in the os.
