[AGL] Can't open midi dev file. Strange error.

[David N. <do...@ma...>]

Hello,
I'm using allegro 4 on Devuan (Debian) Linux. I need a bit of advise
regarding how to trouble shoot this.

% worminator
ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC0D0
failed: No such file or directory

To debug, I started by confirming the existence of the file and that I
have permissions to access it.

% ls -l /dev/snd/midiC2D*
crw-rw----+ 1 root audio 116, 25 Jul  6 21:56 /dev/snd/midiC2D0
crw-rw----+ 1 root audio 116, 26 Jul  6 21:56 /dev/snd/midiC2D1
crw-rw----+ 1 root audio 116, 29 Jul  6 22:19 /dev/snd/midiC2D2
crw-rw----+ 1 root audio 116, 30 Jul  6 22:19 /dev/snd/midiC2D3
% groups
me cdrom floppy sudo audio video users bluetooth

I'm using apparmor as my security suite. I run my own kernel and compiled
out SELinux.

Thanks,
David
