Hmm. Now I'm not so sure what's happening. After setting digi_card in the
allegro.cfg file to "OSSD" instead of "AUTO" (is AUTO even valid?) the
problem went away. I installed the sound with DIGI_AUTODETECT in my program,
and install_sound not once failed... Note that nothing crashed when XMMS was
stopped... Now with digi_card set to OSSD, sound in my app plays
simultaneously with XMMS. To say the least, I'm a bit confused.
I belive I got crashes from screen being NULL, the system driver being NULL,
etc...
