Hey, I have a Unibody Macbook Pro running 10.5.6 and I'm attempting to pair it with a Plantronics Explorer 230 Bluetooth Headset. It pairs and connects easily, and I get audio from my computer but I can't seem to get the mic working. Nothing It's as if there is no mic input at all---the computer doesn't register any sound. I have the headset selected in both input and output under sound prefs, volume is up...I don't know what to do next. Any help? Thanks.
