I seem to recall some issue with the screensaver when music was involved - a fiddle with the settings was a temporary work-around, but I can’t really remember what that work-around was. Searching for and investigating those threads and others may lead to the temporary or permanent cure. Sorry I can’t be more specific.
A blanket approach would be to make sure nothing you have is going to sleep (power saving features, the likely suspects). Beyond that it’s difficult to say.
