Bluetooth speaker crackling

[bleekee]

Hi everyone,

i don't know why when I play movies on mac speakers or another bluetooth speaker, everything works fine.
If i pair the mac on a megaboom 3 speaker it is going to crackle a lot.
But this megaboom speakers is going to crackle only with vlc, not on browers or spotify or nothing else.

Anyone knows how to solve this?
The mac is a MacBook Pro Retina 2013 running Mojave


thanks!
