OpenAL is just like OpenGL, only sound, of course.

It was designed to compliment and mirror OpenGL as a twin set of APIs.

BASS is anything but cross-platform. It is Windows only. FMOD I is cross-platform, including the major consoles too.

In fact I am making use of both SDL and OpenAL in one of my own projects and it works just fine. And setup of JEDI-SDL is do easy monkies can do it.
