CM11 Mic quality is bad topic

I tried using CM12, mic quality is good and "ok google" picks up fast.
However on the latest CM11 nightly build, "ok google" doesn't pick up most of the time. I tried recording my own voice and heck the quality is bad.

Any idea how to fix it? Reason I am using CM11 is because I kinda prefer kitkat over lollipop as of now :p
