Cubase 10.5 sending volume levels to the roof!!

This got me too. I was just living with it. Then I found the post below and that solved it. You need to go into the control panel for your interface in the Cubase Studio Setup and untick “Set Device Attenuation To 0 db”.

Opening Cubase turns my system volume up to max..

One of the studios i work in has Apogee Ensemble audio interface - and same thing occurs. Not only when Cubase is opened, but also whenever in/out ports are reassigned and whenever audio buffer size is changed. Really scary stuff. Almost burned my Genelecs once… Looks like it is a Apogee=Cubase issue. I searched a lot and found no way to fix this. So lowering the volume on your monitors and always working close to maximum system volume would be a workaround.
