Volume increases to deafening levels with each notification topic

I've had my G3 for a couple months now, came from the G2. Love the phone but as far as I can tell its always had this issue. Sorry I root, and ROM my phones almost immediately, although i waited about a week with this one since my computer was down (gotta have access to Flashtool just in case). Anyways I wanna say this was an issue stock also but i may be mistaken. Im currently running Dirty Unicorns Official 9.2 and it seems that anytime I get a text, or any other notification the volume level increases itself beyond 11. I stream music all day while at work with a bluetooth headphones and I'm now deaf in my right ear. I've tried installing Volume boost controls to see if that was the issue, i've poked thru all the settings. But i cant find anything at all that could be cranking the volume up like im at a Pantera concert standing 5 inches from the largest speaker in the house.
But heres another tidbit, if i hit pause, then play again the volume goes back to normal...until i get another notification

So has anyone else had this kinda issue? I'd post this in the Rom thread but like i said I cant be positive its from the ROM, i wanna say it did it when stock too.
