Mar 20 18:18:44 fish-laptop pulseaudio[26345]: main.c: Failed to acquire autospawn lock
And at any rate, it seems that pulseaudio is trying to start it's own instance for timidity, which just changes the problem from timidity and pulseaudio having problems sharing, to pulseaudio and pulseaudio having problems sharing the audio device. (Of course, if the latter case is already possible, then this may work)
