Inspiron 5680, Qualcomm update, poor audio quality

I don't know why I go ahead with these updates. There was nothing wrong with my audio but against better judgement I chose to accept the part of the recent Dell Update which included an update for the Qualcomm wifi & bluetooth. I should have put money on it messing up my audio because NOW my bluetooth headphones sound like a telephone from the 70's -- flat and distant -- and there are all these digital pops and clicks in the background whenever it plays any sound that weren't there before.  

Audio is fine BTW with plugged in headphones.
