I'm using Skype 2.8 (stable/old version) and a BlueParrott bluetooth headset. The bluetooth headset pairs perfectly with my Mac... AND the settings on my Mac and in Skype look 100% correct. BUT, whenever I make a Skype call my INPUT (mic) changes from the bluetooth headset back to the internal microphone of my MacBook!! I don't understand why it switches. It's obvious not good. The listener on the other side can't hear me through the headset. I have to speak through the MB's internal mic. Any ideas? Like I said, all of my settings look good. But, it just automatically switches when I make a call.
