Hey everyone, hope this is the right place for this thread. I have a unibody mbp and my girlfriend just bought a unibody macbook. We are trying to use the video chat feature in ichat and have been having some trouble with the audio. when we start the video chat everything will work perfectly but after a couple minutes of talking she will all of the sudden not be able to hear me talking on her end of things. i am not accidently muting it on my side or anything and if i go into the sound section in system prefs the microphone appears to be working. If i restart my computer and we start the video chat agian it will work for a while again and then cut out. O and i can hear her the entire time she just cant hear me. any help with this would be greatly appreciated.
