The v3 LCXL3 enumerates as 'LCXL3 1', breaking every v2 'Launch Control XL' grep \u2014 present/LEDs/path checks all silently misread. lcxl-path must match the driver's virtual PORT name 'ParVagues LCXL3' (under RtMidiOut client), never chase the PipeWire relay mesh (everything reaches everything via 143)."

Every wireplumber restart tears down Ardour's JACK client; recovery needed a full Ardour relaunch. pactl/wireplumber restart restored the missing HiFi profile after a UCM probe failure (card showed only off/pro-audio)."
