Hydrogen jack audio rendering is broken with pipewire jack client library

I noticed that Hydrogen drum machine audio rendering is broken with pipewire jack client library. hydrogen

Other Hydrogen's audio drivers are fine (PortAudio, Alsa, PulseAudio)

With the Jack One, you hear only saturated noise that stops only when you reset the audio driver, regardless of your drum pattern. As pipewire's jack client library should be a drop in replacement, I report it.

Regards.
