I have the iPhone/iPod in-ear headphones and the first aluminum unibody MacBook. So, I can control the volume and track in iTunes using the buttons on the headphones.
My question is - can I use the microphone as well? I have been doing video conferencing via TinyChat, and although I can hear the audio out my headphones it doesn't seem to be picking up the headphone mic - it's using the Mac's built-in mic instead.
