Audio issues

Hi

Just got Cubase LE 10.5. All loaded on the laptop. Input from keyboard seems be working, but no sound coming out. I have tried Asio4all which i used years back on an old cubase but that hasnt fixed. Gone into the studio setup connected ghe audio drivers. Nothing…
I have a Windows surface pro i5 cpu windows 10 pro 8gb ram. Cubase seems to be running smoothly. What am i missing or do i need to get an external soundcard?

Busses assigned to in- and outputs?
