Description of problem: It seems like some kind of control messages between PA, pipewire, and Jack sometimes are lost. Version-Release number of selected component (if applicable): pipewire0.2-libs-0.2.7-4.fc33.x86_64 pipewire-libs-0.3.19-2.fc33.x86_64 pipewire-0.3.19-2.fc33.x86_64 pipewire-jack-audio-connection-kit-0.3.19-2.fc33.x86_64 pipewire-alsa-0.3.19-2.fc33.x86_64 pipewire-gstreamer-0.3.19-2.fc33.x86_64 pipewire-pulseaudio-0.3.19-2.fc33.x86_64 pipewire-utils-0.3.19-2.fc33.x86_64 pipewire-doc-0.3.19-2.fc33.x86_64 qjackctl-0.6.3-2.fc33.x86_64 How reproducible: Varies. Sometimes 1 in 5 attempts. Sometimes many attempts without "success". Steps to Reproduce: Firefox is running and playing youtube. QjackCtl Graph shows Firefox with output_FL and output_FR connected to playback_FL and playback_FR . I see problems that I seem to be able to reproduce regularly by repeatedly alternating between running two commands: pactl set-default-sink alsa_output.pci-0000:00:1b.0.analog-stereo pactl set-default-sink alsa_output.usb-E-MU_Systems__Inc._E-MU_0404___USB_E-MU-5D-3F04-07D60C0E-004F9-STATION_2-00.analog-stereo 1. Usually, the firefox sound changes to be routed accordingly. But sometimes, the commands do nothing. It works when running the command again. 2. Sometimes, I end up with QjackCtl only showing L as connected (even though R also plays correctly). F5 doesn't fix it. Quitting and restarting QjackCtl shows it correctly. 3. Sometimes (rarely) I end up with QjackCtl only showing output_FL - there is no output_FR. Because the pactl command sometimes is skipped, I guess there at least must be a problem with some messages being lost somewhere in pipewire land - it can't be blamed entirely on QjackCtl.
It could be a manifestation of: https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/392
Thanks. I will test ... but I guess it only is feasible when the fix is available in an rpm, which I expect will be when 0.3.20 lands, probably in a couple of weeks.

Using pipewire-0.3.20-1.fc33.x86_64 I again saw the thing with QjackCtl only showing one firefox output. I will try and see if I can figure out how to reproduce it. What kind of info could help track this down? Some kind of message dump to figure out if PW is sending the right things out?
