I'm a long time guitarix user on Fedora.  I used the package from audinix previously.  I used it last week without problems yet when I tried it today I could not get any sound input into guitarix nor anything out.  What I tried:

* Looking through the dnf logs to see what I may have updated in the last week.  I know I updated all my packages on my fedora 38 system several times in the last week.  I know there haven't been any recent guitarix builds so _something_ else must have changed on my system to cause this problem.

pipewire0.2-libs-0.2.7-9.fc38.x86_64
pipewire-libs-0.3.78-1.fc38.x86_64
pipewire-0.3.78-1.fc38.x86_64
pipewire-jack-audio-connection-kit-libs-0.3.78-1.fc38.x86_64
pipewire-alsa-0.3.78-1.fc38.x86_64
pipewire-gstreamer-0.3.78-1.fc38.x86_64
pipewire-pulseaudio-0.3.78-1.fc38.x86_64
pipewire-utils-0.3.78-1.fc38.x86_64
pipewire-v4l2-0.3.78-1.fc38.x86_64
pipewire-jack-audio-connection-kit-devel-0.3.78-1.fc38.x86_64
pipewire-codec-aptx-0.3.78-1.fc38.x86_64
pipewire-jack-audio-connection-kit-0.3.78-1.fc38.x86_64


* I used other jack aware tools like carla to make sure they were still able to use pipewire.  This worked.
* I used carla's input monitor to make sure there was signal coming from all audio sources.
* I tried wiring my microphone up to guitarix to rule out a problem with my behring umc22.  This did not work
* I tried using other software with my behring umc22.  This worked.
* I did not see any errors in the guitarix logs.
* I tried using guitarix's "Jack Ports" feature to tried another way to connect my input source.  I get an error if I try selecting anything.  It says: "[20:25:48]  port connection  ***  couldn't connect gx_head_amp:in_0 -> USB PnP Audio Device Mono:capture_MONO".  I don't know if this is even a valid test.  I always used qjackctl before.
* I tried rebuilding the fedora 38 SRPM.  It had a dependency on jack-audio-connection-kit-devel.  I changed it to pipewire-jack-audio-connection-kit-devel to see if somehow that would work.  It didn't seem to change anything so I erased my build and reinstalled the official package from Fedora.

Reproducible: Always
