0. JACK: input
0. Steal PulseAudio's default channel maps per channel count
0. Ability to parse PulseAudio's "front-left" "front-right" channel label strings
0. When two soundio clients are talking to each other, use port names to
negotiate channel maps.
0. JACK: implement prebuffering
0. why does pulseaudio microphone use up all the CPU?
0. merge in/out stream structures and functions?
