No audio signal in stereo out during audio recording

No audio signal in stereo out during audio recording.
Possible record and listen after.
But during recording from the microphone don’t hear sound at all.
What the problem?
Midi works fine.
Cubase 10.5

Could be a lot of things, and really hard o tell, with so little info.
Check if you are in “direct monitorig” mode.
And “Cubase 10.5” is not an available Cubase version.
