Topic: Fireface 802 ok with reaper but windows don't see

Hello
I have my Fireface 802via USB to my PC (Windows 10). I work in Reaper, everything is fine, I can select the RME device there as usual.
But I can't select the Fireface 802 as an output audio device in the Windows system settings (it just doesn't show up).
I miss something?

I answer myself (thanks to me).
Activate WDM Device in the setting
