Auditioning not working in Pro 10.5

I just upgraded from Pro 10 to Pro 10.5 and found, to my disappointment, that auditioning is not working. Not with the speaker tool, or in the pool, or in the sample editor, or in Vari-Audio (won’t sound the note when clicking on a segment).

To check, I loaded Pro 10, and auditioning worked fine. So it’s something doing with (my?) Pro 10.5.

Any suggestions would be most welcome!

Set up comtrol room correctly or if you donˋt use it, disable it.

Solved. Yes, I was still monitoring via phones when using VST Connect. Just needed to monitor via mains. Thanks.
