Module: JACK

The jack module displays the current state of the JACK server. Supports both JACK2 and PipeWire implementations of the JACK API.

NOTE: PipeWire users are advised to upgrade to v0.3.57 at minimum; earlier versions without this bugfix cause the Waybar client to hang indefinitely if the server shuts down while the Waybar module is running.
