Hi,
I'm using a PreSonus Studio 1810c interface which can run at 44100, 48000, 88200, 96000, 176400, 192000.
However, in Ubuntu Studio and Mint I can only pick 88200 and 96000, both of which are far above my requirements and lead to pops, crackles and x-runs in Reaper, even at 512 spls.
The rest are missing from the Studio Controls drop-down and the stream0 file:

For comparison, this is the stream0 file for the Focusrite S4i4 which I've fallen back on:

The full range of sample rates is available in the AVLinux Pipewire Metadata box. When I tried to test it out in Reaper the inputs kept on being disconnected and reconnected in a different order, but at least I could select the sample rates in the Metadata box.
Does anybody know what's happening and how I can fix it?
Thanks.
