Steinberg Elements 11 UR44C. Mac no sound

Hi everyone
I was able to install the driver for my audio interface Steinberg UR44C on my Mac
I am able to use the UR-C dspmixfx and see signal in my input 1
In the Mac audio Devices setup menu I can see the UR44C device (nevertheless impossible to play with Master mainstream function is it normal ?)
Studio \ Studio audio connections the audio device UR44C is selected for the inputs and output
Studio \ Studio setup all the I\O are active

Do you have an idea of what is missing I spent few hours to figure that out before posting on this forum

Can you help me ?

Hi and welcome,

Make sure Cubase has enabled Mic in the System Preferences, please.
Open macOS System Preferences > Security & Privacy > Privacy > Microphone. Enable Cubase here.
