The jack-tunnel module provides a source or sink that tunnels all audio to a JACK server.

This module is usually used together with JACK DBus detect that will automatically load the tunnel with the right parameters based on dbus information.

Example configuration of a duplex sink/source

context.modules = [
{   name = libpipewire-module-jack-tunnel
    args = {
        #jack.library     = libjack.so.0
        #jack.server      = null
        #jack.client-name = PipeWire
        #jack.connect     = true
        #tunnel.mode      = duplex
        #midi.ports       = 0
        #audio.channels   = 2
        #audio.position   = [ FL FR ]
        source.props = {
            # extra sink properties
        }
        sink.props = {
            # extra sink properties
        }
    }
