Hi! I'd first try running miniFmSynth in a debugger. gdb in the console or something else in a gui. with gdb it would look like: bash-prompt:~ # gdb ./miniFmSynth [options you like] gdb> run [some error message] gdb> traceback Not sure about the traceback command, but you could try help. It will tell you, where it failed. If you can't understand this directly, someone else here most certainly can. You could check your alsa-version should be >0.9.4 You can try using aplay to play a sound (which is alsa-basic equipment) and you could try some other midi-sequencer/synth to test midi/audio. Try fluidsynth, ams, ZynAddSubFX or the like... HTH.
