Comment 2 for bug 128447

libsdl-all is indeed the unified package that include every sound engine.

Problem is
1) every independant engine excludes the others (i.e. installing libsdl-pulseaudio removes libsdl-alsa for example)
2) some apps are built with a specific engine (to be honest, I only saw this once with a package for Second Life that was dependant of libsdl-alsa; although it's unusual, it can happen)

Would it be possible to make every engine (every package) installable simultaneously and changing libsdl-all as a metapackage that would just install all the specific ones ?
