My MacBook Pro bluetooth cuts out when playing music

Macbook Pro mid-2012 still under warranty with El Capitan

I think this might be a common problem with recent Macbook Pros.

Playing music or audio from a video, the sound cuts out, silence, cuts in ... cuts out again...

It seems like the buffer size is too small in the devices, but it doesnt happen with my wife's little Macbook Air, so it seems to be the Bluetooth manager in my MBP.

I did find this in Apple Discussions:

defaults write "Apple Bitpool Min (editable)" 40

But it did not seem to affect anything.

Is this a good question?

I should have specified,

defaults write "Apple Bitpool Min (editable)" 40

is a Terminal command.

Gee, I have no problems ... I have a UE2 running with El Capitan off of either iTunes locally or YouTube

Are you sure it's the Bluetooth and not the app or the network connection to the audio/video source?

What is the app you are using and are you using the latest version? How are you connecting to the music/video is it on your system, over a WiFi connection to a local system (server) or off of the internet as a stream?

Update (11/03/2016)

Try this: Create a bootable external drive (USB thumb drive). Using it as your boot drive see if iTunes works that way cleanly. That way you're removing all of the stuff from loading without altering your drive for now.

Thank you for the reply, Dan. "Are you sure it's the Bluetooth and not the app or the network connection to the audio/video source? " It happens with both VLC playing video, iTunes, the Finder (spacebar preview), Miro (an iTunes replacement) and Safari playing an audio stream. Oddly enough, Audacity, a sound file editor, returns data on the Bluetooth device but plays through the internal speaker but i think that is an irrelevant app specific characteristic.

As i sit and think about it, i have two add-on softwares that address the system's audio library, Boom 2, and Audio Hijack. These two manipulate the audio upstream in the system. They now are my prime suspects. Uninstalling either is a major hassle.

As to your second question, I am connecting with my Wifi router and as i said, no problem with my wife's laptop Bluetooth on any device.
