I hit stop, made the change, and hit start in QJackCtl and it still shows 1024 in Reaper and I cannot seem to budge it.
How do I change the sample rate and frames per period?
It seems Reaper must command 1024 but I have no idea how to change it?

UPDATE: I think the problem is that I had installed Pipewire. I tested the same changes on two other Ubuntu installs and I can change settings.
Is there a way to remove all traces of Pipewire and Jack and start fresh?

Yes, but like the Terminator, you have to go back in time and execute some linux developers.

On Debian I have to start qjackctl on the command line with:
pw-jack qjackctl
which will make Jack act as normal. (As far as I can see.)
You probably don't need QJackCtl to start the pipewire JACK emulation, at least in Ubuntu 22.04. I don't (personally I switched to the KXStudio tools--Claudia, etc, over QJackCtl for JACK2 some time ago, but that's not required now, as well).
Yeah, the default buffer size is set to 1024 in Pipewire. You can reconfigure that, although configuring Pipewire isn't that straight-forward.
If it's just the buffer size, here's a work-around: use the RaySession session manager; the GUI has drop-down buffer setting. Change it once, and it will stick (until reboot or logout).
Plus the patchbay in RaySession is really good -- but it doesn't show ALSA MIDI connections (neither does Claudia, I think). The qpwgraph patchbay does show ALSA connections, tho.
For sample-rate, you should edit the config files.

Now it does in git master version, so ALSA MIDI support will be available on next release.
