Displays the current volume level.
Clicking on the widget opens a volume mixer, which allows you to change the device output level,
the default playback device, and control application volume levels individually.
Use `truncate` option to control the display of application titles in the volume mixer.

This requires PulseAudio to function (`pipewire-pulse` is supported).
