annotate src/cdrom/macosx/AudioFileReaderThread.c @ 3798:c8b3d3d13ed1 SDL-ryan-multiple-audio-device

Audio bootstraps can now specify that a driver is only to be used if explicitly requested (for things like the "disk" driver that is always available but you would never want to default to using). Trimmed out code that can be handled by stubs in the core. The "dummy" driver is pretty damned small now. :)
