sdl-ios-xcode: src/audio/macrom/SDL

annotate src/audio/macrom/SDL_romaudio.c @ 3846:66fb40445587 SDL-ryan-multiple-audio-device

Removed distinction between "available" and "init" in audio backends, since both had to be checked for success as a pair at the higher level and several of the Available methods were just always-succeed placeholders anyhow. Now the availability check is done in the init code, and the higher level tries all possible drivers until one manages to initialize successfully.
