so I compiled/installed allegro 4.4.2 from source in Ubuntu and everything works fine except the sound even though install_sound(DIGI_AUTODETECT,0,0) returns 0. I searched the forums and it seems that this is a well known bug probably related to the jack audio module used by Ubuntu instead of the alsa module. I tried everything I could find but nothing worked so far.
However, then I installed the prebuild Ubuntu package of allegro 4.4.2 and the sound worked just fine. So it seems that there is some way to compile/install it and get it working. Does anyone have an idea what's the trick here?
(And yes, I still want to build allegro by myself instead of using the package )
