 // Package pulseaudio is a pure-Go (no libpulse) implementation of the PulseAudio native protocol.

-// Rather than exposing the PulseAudio protocol directly this library attempts to hide

-// Some of the things which are deliberately not exposed in the API are:
-//
-// → backwards compatibility for old PulseAudio servers
-//
-// → transport mechanism used for the connection (Unix sockets / memfd / shm)
-//
-// → encoding used in the pulseaudio-native protocol
-//
-// Working features
-//
-// Querying and setting the volume.
-//
-// Listing audio outputs.
-//
-// Changing the default audio output.
