The audio input of my MBP 15" 2011 is pretty bad no matter if the
ambient noise reduction is checked or not.
I've tried all kinds of sound adjustments from the control panel but I can't get it good.
In order to tell you what's the sound quality with words: If I make an audio call the other person doesn't hear me well and have to set an upper level to understand me. If I type something on the keyboard, then the callee become deaf instantly.
So the fan & keyboard sounds are very loud whereas my voice is quite low. How can I (try to) fix this?
