I am running Fedora 28 and Doomsday (both stable and build 2774) with success (mostly), but am unable to get the music to play on Ultimate Doom (Steam). Sound effects work perfectly. I have attempted to get the default music to play, and a few music addons with no success. This occurs with both a stock Doom install, and one with addons.
I have also tried switching between fmod, fluidsynth and sdl_mixer to no avail. The only feedback I get is that when I use SDL_mixer it says that the linked version is newer than expected, being 2.0.2. Is this a hardcoded filepath issue with the libraries?
Does anyone have any tips? Happy to do further debugging if required.
