Did you already try the Generic Low Latency ASIO Driver that comes with Cubase? In the settings of this driver (Studio > Studio Setup > Audio System) it should be possible to select the audio output device of your laptop. So, probably there’s no need to install ASIO4ALL.
Thank you for your guide!
I have followed it, and it guided me further, but unluckly I still wasn’t able to hear audio neither with speakers nor with bluetooth headphones.
I don’t know what to do more. I’ll try to ask help to a friend who is both tech-savy and a musician. Meanwhile I’ll switch to Music Maker, which is a shame because Cubase is far more powerful and full of features.
