This has been happening for like a year at this point.

When I'm connected to a bluetooth speaker, and playing a song from iTunes while working, the audio stutters every so often. Sometimes it'll be silent for a good 2-3 seconds. It's super frustrating, even more so because I've searched all over the internet and haven't found a solution for it. I've done all of the usual things (PRAM reset, SMC reset, AHT, etc.) but it hasn't helped.

I'm not really sure what to do at this point. Any advice? Has anyone had the same problem?

I'm using a mid-2012 Macbook Pro, 15 inch, on Mojave. I have the problem with my JBL Flip 3 and Bose Mini SoundLink.
