I'm using a DR-BT22A by sony, it's a wireless bluetooth headset. It's connected to the pc as a headset, as it works fine with skype, however when doing the audio/video setup in yahoo messenger for voice calls it doesn't recognize the microphone at all, nor does it send audio to the headphones when testing the speakers. I've googled the hell out of the problem and am still at a loss to figure this out.
