- quit using select() for audio playback. we end up counting bytes
in the playback buffer and waiting until there's enough space anyway. - use -pthread instead of -lpthread for pthreads linkage - don't even try to use the "real time sample counter" on *BSD, since it's not that same as with Sun audio. - use the audio(4) interface to the mixer "master" volume control - actually mute the audio when output volume is '0' - set the audio(4) blocksize to match size of chunks to be written - provide *BSD equivilents to some Sun functionality
