Feedback on Speaker Phone

[talkinggoat]

Asus Z00AD and Asus Z00TD both have issues where there is massive feedback when either the video or audio are put into speakerphone. I tried turning off all the audio settings, but it didn't help. Also, I can not disable "Automatic gain control" on the Z00AD. It will uncheck, but when I come back, it's re-enabled.
