No sound using ASIO4ALL or generic driver on laptop

Using Cubase 10.5 on Windows 10 and Realtek soundcard on laptop.

Sound output is fine using ASIO driver for my audio interface but I can get no sound output if using the generic driver or ASIO4ALL. The generic driver offers no option at all for selecting the Realtek soundcard and ASIO4ALL defaults to the spdf output with no option to select the HD output.

Can anyone advise how to get sound out when not using a usb audio interface.
