@riomccloud looks like it is building fine. How do I test whether support for SDL mixer X is working as intended?

@ghisvail It's been a while since I worked on that PR, but if I'm not mistaken, SDL Mixer X was a requirement for MIDI audio to be played correctly in SRB2. I installed the build here, but the MIDI audio still doesn't work. Console prints this when disabling digital audio and enabling MIDI:

ERROR: Mix_LoadMUS_RW: Timidity: Can't initialize library
ERROR: Music _clear could not be loaded: engine failure!
