Bluetooth audio choppy/skips on El Capitan

I'm using the music receiver bluetooth TP-Link HA100 and when doing streaming from Spotify or iTunes the audio has clicks in and out and skips like a scratched CD. Simply unusable. I'm on MacBookPro late-2011 El Capitan 10.11.2

This is a known issue, I already tried these unofficial solutions:

https://discussions.apple.com/thread/7263274?start=0&tstart=0

but they don't work.

Note 1: the audio lags/skips seems to increase everytime I do something on Mac (that is, open an app, scrolling a page in Chrome, ...).

Note 2: no one of the above issues on iPhone and iPad

Note 3: while streaming from iPhone/iPad if I just enable bluetooth (not stream) on MBP the audio begins to lag!

It's a lot frustrating and I can't believe bluetooth con OSX is so much crappy and there's no bugfixes on the horizon! Someone can help me?

Solution 1:

I have found yet another unofficial solution! it worked for me and i hope the same to you. i believe the macbook utilizes bluetooth in the background for handoff and FaceTime. i believe it searches occasionally for data or cues that are sent from secondary devices or stays quietly paired with a device you may already have (causing gaps in bluetooth connectivity). i signed out of FaceTime (disabling it) and disabled handoff. i have an iphone, and it seemed to create some kind of bluetooth interference. try this and see if it doesnt help or solve the issue

Solution 2:

wireless mouse interferes with bluetooth

Solution 3:

I tried all the listed solutions and nothing worked for me on MAC Sierra.

Just the:

sudo killall coreaudiod

worked for me but only for max 1 hour. Than I had to reenter which is quite annoying.

The bluetooth sound quality was dropping extremely especially while playing videos (high CPU and memory usage). It was unbearable.

What finally worked:

I activated the sound equalizer which I already had installed but never used: "boom2" (unfortunately not a free applications; may be there are other apps free which might work as well).

This software resides between the Audio source (in my case Video application) and the bluetooth processing unit of MAC Sierra.

Because the bluetooth part remains in this solution unchanged the problem can not be related to bluetooth buffers or frequency interference on the radio waves itself.

It is a problem of the operating system itself.

I hope this solution might help others as well but I can not assure that this works in your specific environment.
