ahhh! just found this - Opening a 44.1kHz session with pw-jack - #5 by automaciej
Sorted 
hi, I just recently upgraded ubuntu from 22 to 24.04 via a fresh install. I’m not very technical and have struggled to get ardour working with pipewire, however it’s pretty much working now and I can record via my scarlet 2i4. I can see pipewire connections via Helvum. I can record the audio from firefox. Today I tried recording from a CD using VLC player. This worked too although the connections from VLC to Ardour at one point seemed to disappear if I stopped recording. The main point though, is that it was recording at 48000, and I can’t see how to change that to 44100 for a CD, this is the problem.
I’m launching ardour in Terminal with
pw-jack -v -s 44100 Ardour8 i.e. verbose
When I create a new session the edit window opens with no chance to set sample rate, frames etc. In qjackctl Setup I have 44100 and 1024 frames/period. I spent some hours earlier with MS Copilot troubleshooting and it said to create a file with the 44.1 option in so I have
/usr/share/pipewire/pipewire.conf.d/10-rates.conf
which looks like
context.exec = [
{ path = “/usr/bin/pipewire” args = [“-r”] }
]
context.properties = {
default.clock.allowed-rates = [ 44100 48000 ]
}
I was hoping to attach the verbose output and also the qjackctl Messages window but .txt files won’t upload.
Any help will be much appreciated.
Here is qjackctl -
