| infrared | Attempting to play the Chzo Mythos series (http://icculus.org/~hamish/chzo/) with AGS compiled from source (downloaded on Sep 12). When starting a game, MIDI music is not played (it is supplied in a Music folder in the same location as the game exe), and the terminal reports: Checking sound inits. AGS: Initialize sound drivers AGS: Trying digital driver ID: 'Auto' (0xffffffff), MIDI driver ID: 'Auto' (0xffffffff) ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC0D0 failed: No such file or directory Unable to initialize your audio hardware. [Problem: /dev/sequencer: No such file or directory] AGS: Installed digital driver ID: 'ALSA' (0x414c5341), MIDI driver ID: 'None' (0x0) To try and get music working, I downloaded a patchset from http://www.eglebbk.dds.nl/program/download/digmid.dat and put it into the same directory as the game executable as patches.dat. This had no effect. Afterwards, with timidity server running (ALSA port 128), I tried sudo modprobe snd_virmidi cd /dev/snd/ sudo ln -s midiC2D0 midiC0D0 aconnect 24 128 At this point AGS stopped complaining about not finding midiC0D0 or /dev/sequencer, but still did not play any music. Using: amidi -p hw:VirMIDI,0 -d shows that the port which was linked to does not receive anything, so AGS is apparently not even trying to play MIDI.
