Hey all, I have an early 2011 15 inch mbp and I had some problems with the facetime app lately (3 times this week), so here's the situation: I start having a facetime conversation with someone and after 2-3 minutes, the person with who I'm speaking tells me she/he can't hear me anymore, even if the camera still works, it looks like my microphone turns off. I've open the system preferences and noticed that my mic seems to work properly but people just can't here me. The only way so far I found to make it work again i to do a restrart which is really annoying. I have no idea if it's a software or hardware problem....anybody can help? thanks ! P.s.: sorry if I made some mistakes writting this down, english is not my first language!
