Music and videos pausing randomly

[Hugo Nebula]

My LG G6 has developed a problem over the last couple of months where it will pause music or video playback at random.

It happens with wired and wireless headphones, bluetooth speaker, and without headphones. It happens using the LG Music app, Google Play Music, YouTube, VLC, etc. It can go a few songs without happening or several times a track.

I've removed any apps I've installed in the last few months, but it still does it. I've turned on Ignore Optimisation for any music or video but no luck.

Any ideas?
