No sound metronome audio

Cubase PC user for 25 years.
Never had an issue with default audio metronome.
Just transitioned to a Mac.
I can get the midi to work but no metronome audio coming out.
Audio working fine for everything else.
In metronome setup:
Metronome On.
Use Audio Click
Click while playing
Audio click sounds - use Steinberg Click Sound

Audio interface was the issue.
Problem resolved.
