 SQUEEZELITE_UNMUTE|-U|From squeezelite's man page for `-U`: Unmute the given ALSA `control` at daemon startup and set it to full volume. Use software volume adjustment for playback. This option is mutually exclusive with the -V option. Only applicable when using ALSA output.
 SQUEEZELITE_LINEAR_VOLUME|-X|Set to `Y` to enable. From squeezelite's man page for `-X`: Use linear volume adjustments instead of in terms of dB (only for hardware volume control).
 SQUEEZELITE_VISUALIZER|-v|Set to `Y` to enable. Unfortunately this feature does not really work from inside docker (yet?). From squeezelite's man page for `-v`: Enable visualiser support.  This creates a shared memory segment that contains some of the audio being played, so that an external visualiser can read and process this to create visualisations.
