Ensures that a certain set of JACK ports are always connected to each other (if they are present)

jack-autoplug

A tiny utility that ensures that a certain set of JACK ports are always connected to each other (if they are present).

Building

Like any Rust application: cargo build --release produces the binary at target/release/jack-autoplug.

Running

Check out --help for a synopsis. For a practical example, I use this with PipeWire's JACK API emulation to take the audio from a HDMI capture card and patch it through to my headphones immediately like this (names replaced with dummy values for clarity):

$ pw-jack jack-autoplug -f "HDMI Capture Card Analog Stereo" -F capture_FL -F capture_FR -t "Headphone Device" -T playback_FL -T playback_FR

This connects the capture_FL port of the capture card with the playback_FL port of the headphones, and same for the FR ports. If any of the two devices vanishes, the port connections will obviously be lost, but jack-autoplug will restore them as soon as the device reappears.
