`sound-manager` is a CLI interface for managing PulseAudio sinks (speakers),
sink-inputs (programs producing sound), sources (microphones), and
source-outputs (programs recording sound).

Additionally, the `elusive-events.py` script can aid in setting e.g. the volume
on very short-lived sound effects, like the terminal bel. Run
`elusive-events.py -h` for usage info.
