Default [Help] Bluetooth device controls phone volume with 4.4 but not Kit Kat 4.4.2

Help! I've been frustrated with this problem of controlling my phone's volume with my Bluetooth headphones. It was working perfectly with Kit-Kat 4.4.0, but after upgrading to 4.4.2 I can no longer control the volume, so now I have to deal with two volume controls (phone and bluetooth device). WHAT IS THE FIX TO RESTORE FUNCTIONALITY!!!

I flashed 4.4 (krt16m) and bluetooth volume control was working perfectly, then I flashed 4.4.2 (hot49h) and it stopped working. I flashed back to 4.4 (krt16m) and it worked again. When I'm flashing I'm using the stock Google images from: https://developers.google.com/androi...ges#hammerhead

I tried to Google the solution, but everyone is complaining with no answer, neither in these XDA forums.
