--- Comment #6 from Marc Payne marc321@gmail.com 2008-03-30 21:26:12 --- Thanks for the screenshots. Those are the same glitches I experienced. Since switching to OSS, the toolbar icons seem to appear every time... even after deleting my ~/.wine directory and starting over. Ghosts? ;-)
I installed TiMidity and ran it with "timidity -iA", which creates four Alsa sequencer ports. Wine sees the ports and populates the OSS "MIDI Out Devices" list with them. Choosing one of those ports via "Setup -> MIDI Devices quick setup..." in Composer enables playback, which is flawless. I am satisfied to have sound and no crashes, but there is still the question of why Composer crashed with Alsa.
