The command "pactl set-sink-mute ${@DEFAULT_SINK@} toggle" is used to toggle the mute status of the default audio output sink using the PulseAudio command-line tool (pactl).
Let's break down the command:
- The "pactl" command is used to control the PulseAudio sound server from the command line.
- "set-sink-mute" is a pactl command that allows you to change the mute status of a specific audio output sink.
- "${@DEFAULT_SINK@}" is a placeholder representing the default audio output sink. It is a variable that expands to the name or index of the default sink.
- "toggle" is an argument supplied to the "set-sink-mute" command, instructing it to toggle (i.e., switch between) the current mute status. If the sink is currently muted, it will be unmuted, and vice versa.
In summary, this command is used to conveniently toggle the mute status of the default audio output sink using the pactl tool.
