Sample audio rate not supported in Adobe Premier on Mac Ultra Studio

I'm trying to edit a video in Adobe Premier. I can see the sound is there on the timeline, but it will not play. I get an error that says "sample rate not supported but audio hardware" but it's at 4800 Hz. So I don't understand what the problem is.

Sound plays on a web browser, but not in premier, and it appears to be a Mac HW issue. How can I fix this?

Clicking on Attempt to force hardware to sample rate does nothing.

thanks
