QJackctl Flatpak Request

Project information: JACK Audio Connection Kit - Qt GUI Interface
QjackCtl is a simple Qt application to control the JACK sound server daemon, specific for the Linux Audio Desktop infrastructure.

Written in C++ around the Qt framework for X11, most exclusively using Qt Designer.

Provides a simple GUI dialog for setting several JACK daemon parameters, which are properly saved between sessions, and a way control of the status of the audio server daemon. With time, this primordial interface has become richer by including a enhanced patchbay and connection control features.

There is Helvum that work for pipewire. Plain JACK will never work on Flatpak, so qjackctl doesn’t really provide anything that Helvum will not.
