Hi, Mauri !!
And, you 're welcome!!
Sorry, I should have clarified that you can check in the HDSP Driver settings, under "WDM Devices" section, for your WDM Devices.
WDM stands for "Windows Driver Model" and is the standard Windows driver which is used for audio.
So RME has included a section where we can choose which I/O is to be used by Windows.
If you have any I/O configured as WDM Devices, just uncheck them all and check if the issue with Cubase, persists!
Also, make sure that RME ASIO Driver is selected in Cubase 's settings!
Then, please, report back!!
