audio really loud after update

Going from 1663, mega install, to 1667, update quick install sound is really loud.

I need more details. Does it happen with all files, including stereo and 5.1 tracks? What is your speaker configuration?

I'm using headphones. It seems to happen with all files, mp4, mkv, mp3.

It's not really a serious issue. I can turn down the volume to the program in windows (8.1)volume mixer and then inside MPC to get it back to where it used to be.

With both volume settings max it is painfully loud. I didn't realize headphone volume could get this loud.
