Cubase 11 Trial

I had a problem after reinstalling Cubase 7.5 on my Microsoft Surface 3 Laptop - 64 bit 16GB RAM. Windows 10.

I couldn’t get the audio output to sound through the internal sound. The meters on Cubase worked so I can confirm that Cubase itself was producing the output.

I have now installed Cubase 11 Trial. I still can’t get the audio to comeout of the internal speakers.

Is there something(s) I can check?

I am trying to record some test audio via the internal mic. The audio input/output are set to internal.
The level meters do not move (!)
The demo projects do not output the sounds (but the level meters move).
The laptop plays WAV and other media files with no problem. Inc. YouTube and other streamed media.

What can I check?

Thanks
