I just got my new MacBook today (2.16 ghz) and it seems to be having audio issues? I was chatting with video chat with my friend and I could hear him fine. Then all of a sudden i noticed the sound cut out. I plugged in my ipod and sound seems to be cutting out on that too. When I hit the volume keys, a circle with the line shows up like it's muted or something and I can't turn it up or down. I can hear the system sounds okay like on restart, but everything else seems to be acting weird? I only have 1GB of ram, but to me that should be suffice until I get more. Any else hear of this? I hope I don't have to return it already to applecare, I just got it!
