Asio direct monitoring not working

My direct monitoring check box is greyed out. Direct monitoring has worked fine until now. How do I get it to work?

Have you selected the correct asio driver? It may have changed to the generic one if the audio interface had been unplugged at some point.

Yes but the direct monitor is greyed out can’t check box.

You don’t say what interface you have. Some have buttons on for direct monitor as well. Has that been pushed by mistake. Knowing the interface would make a huge difference for anyone trying to help.

Steinberg UR44

So you definitely have chosen the Yamaha asio driver and the unit is nit in cc mode?

Correct

Did you ever fix this?
