RNBO Target Export Error - Could not activate runner's audio, please check your audio configuration settings

I am trying to export one of the RNBO guitar pedal patches to my Raspberry Pi 4. I can see the target listed, I can ssh in, and everything on the RPI seems to be fine from what I can tell. But when I try to export, I get the following error:

Starting Code Generation
Generating Objects
Compiling Patcher
Printing CPP Code
Sending config
Sending code
Sending patcher
Compiling
Could not activate runner's audio, please check your audio configuration settings

Does anybody know what the problem is?

If I use the "Dummy" interface it seems to export fine. But when I try to use my USB interface (Presonus Studio 1810) or any other interface I get the error.

HMM.. have you tried changing the other settings, sample rate, period frames, num periods?

If none of that works, are you able to ssh to your pi and run

journalctl -u rnbooscquery -f

and then try an export and post the output here?

I tried all of those items and it did not work. I ended up switching instead to an even older USB audio interface I had (a Roland V-Studio 100) and it worked right away. I'm not sure why my Presonus Studio 1810 did not work, but now that I have a working I/O solution I am all set. Thanks!
