Hmmm, this is weird, my msn isn't taking input from from my microphone, it takes the audio playing on the PC instead. So when I am playing a song, the other side can hear it clearly, but they can't hear my voice. The mic isn't broken as I can hear my own voice from the speaker when I talked into it. I tried to unplug the mic and my friend still can hear the song playing. It happens when I was using MSN6.2, and I upgraded to MSN 7.0 Beta a while ago but it doesn't do any help. Any idea on what goes wrong?
