Mic problem when making or receiving phone call on Yosemite

[PilotTiny]

Hey everyone,

So I have the Yosemite public beta on my Hackintosh and iOS 8 beta 4 on my iPhone 5. The problem is when I make or receive a phone call from Yosemite, I can hear the other person through my speakers but they cannot hear me. I have checked that my Mic is enabled in System Preferences and under FaceTime, but it still doesn't work. Any ideas? Thanks

I'm having the same issue. My microphone isn't working at all. When I try to record a video in photo booth, it crashes. My mic isn't working for FaceTime calls either. I don't have a hackintosh. I have a 2010 15" MacBook Pro running OS X Yosemite beta, Build: 14A299l Released On: July 24, 2014.
