Unfortunately, everything looks good in QJackctl. My guess is that this iteration of pipewire isn't handling the internal Qtractor routes properly, but I'm not sure as to how I can verify that. As I said, the instrument channels do send to the first bus, but the busses don't send to other busses. Do you have an appimage or an ubuntu flavor .deb repo for your qpwgraph? Looks like these qt pipewire projects are all in raw source (which I NEVER have good luck with or the trouble-shooting time to sort it out).
