With default config Allegro tries to use PulseAudio sound driver as first. On my system, which has PulseAudio installed, but disabled in its configuration, this makes al_install_audio to quietly hang forever. It works after setting alsa driver in allegro5rc file.

I'm using Debian sid on amd64.

Allegro version: git 3b0b89df32068922407075bfeb1ab3fbf7bba572 (Sat Jan 5 23:41:24 2013 +0100)
