@retrochip said in Mupen64Plus problems (audio + video):

The only option I see so far is to use the 'Mupen64Plus SDL Audio Plugin' v2.5.9 plugin, but how do I do it? The script mupen64plus.sh should set it (am I wrong?), but if use the old one, it does not change anything and the 'Mupen64Plus SDL Audio Plugin' v2.5.9 plugin is still used.

it should. after a launch, what is the contents of /dev/shm/runcommand.info please?
