Sound out from iMac

Does anyone have Cubase pro 11 installed on an iMac with Catalina?I can’t get any sound to my internal speakers no matter what.Is there a setting within the iMac not on the sound menu I don’t know about?Im using an Apollo twin DAC. with a Yamaha CP88 piano.


In this case set the built-in Audio Device as the ASIO Driver.

The sample-rate should be set the same in both your Mac settings and Cubase.
