Front Audio Mic issue

When I select Microphone boost for the front pink in (with or without Mic plugged in) the Audio starts to crap out. The only reason I can think is that because the grounding wire used for Mic in and Audio out are the same.

Note that when this crap out happens and when I record from the Mic In the audio that is played is being recorded at a looooooooooooooow volume. :wave: the board is Foxconn G31MX-K on ALC662 Realtek
