When I fire up a vid to watch on my netbook there is often no sound. If I play an audio file the sound works correctly. If I then go back to the vid and play it again the sound works just fine. I have a desktop machine with the same setup and this is never a issue. Has anyone else come across this?
Software:
KDE neon
VLC (but the problem is the same with any vid player)
Qmmp
ETA: A recent update appears to have fixed this problem.

No patches. It’s straight out of the box installation and not the slightest bit fancy. The good news is that my first ever pair of Bluetooth speakers arrived today and they connected to every Linux device without any issues.
