I'm getting the loud buzz similar to what everyone (including myself) was getting before the 7.2.2 PP release. It only happens when it's trying to load or scrub audio from a source stored on a dormant drive (like a rugged drive that hasn't been used for a few minutes), or right after I open a new sequence tab. It doesn't matter what volume my source or headphones are at either. It seems like it's full volume no matter what.
