I know. I think I rememeber Steinberg was bought from another big company some time ago. Its like everywhere. They need some more experts in the support team, but because of the money they split one expert position to two students jobs. In this case it might be more an mission for an programmer
I found a workaround of another member here , which works for me. If you don’t set to rememeber the interface in the pop up menu when cubase is startet the first time after installation, the audio hardware menu do not dissapear. I found out that there must be a problem with an specific file in the App Data Folder of Cubase (Windows).But I am not on the run to search for it .
I got an old tool from the internet called: Push the freakin’ button.It was free in past. Now this tools presses the pop up menu for me at startup and the audio hardware menu do not disappear anymore. The tool take some cpu but I am using Process Lasso to Limit its usage. If I am running out of Perfomance i still can turn it off. It takes 0,05 % on my Intel7 6700K. The newer Version of the Push the freakin’ button costs around 30 dollars I think. I found the version named PTFB1064 and it works.
