For example, using the standard PulseAudio volume control (
pavucontrol):It would even be possible to do things like add the current track's title and artist in env variables, but I don't think anyone actually makes use of this, so it seems rather pointless to me. Instead, I decided to focus on the most useful ones.
Librespot only sets those when used as a standalone binary, but not as a library: https://github.com/librespot-org/librespot/blob/054074c920d5c6acf0210faa3cd849dc4e065828/src/main.rs#L1211-L1246
