i have this problem for a long time now, but do not know, if it is there all the time. Just regonize it everytime i need the functions, which can be set in the audio hardware menü. because of other problems. I have to renew/delete the pref folder of cubase very often. So I am sure the Problem occur more than one time after i deleted the prefs folder. i make saftey ,copys of the pref folder of cuabse which is sdaves under app data in my win 10 system. so today i tried it with an old folder i saved a month ago. i think the problem is getting worse. i believe that it was better with an older version of some drivers or cubase versions. but do not know which versions, an i am tired of buggering around with it . ( hope you don’t mind my bad english
