segfault in outb - snd_rawmidi_write()

[fenugrec]

Describe the bug Trying to run https://dosmid.sourceforge.net/ on a freedos image

To Reproduce

1. configure machine as 486 with sb16 sound card
2. try to play a midi file with dosmid.
3. ( I wasn't able to reproduce this by just executing an OUT AL,DX with DX=0x330 in DEBUG )
4. segfault

Expected behavior Some kind of playback, or at least not a crash

Screenshots

Emulator configuration

• Machine: ami486
• CPU: 486/dx50
• Graphics/sound cards: vga, sb16
• Installed OS freedos

Host machine

• OS: archlinux, alsa-lib 1.2.11
• Emulator version : built from git

Additional context I'm not sure why it's trying to open and access a raw ALSA midi device, since its configured for sb16?
