On my machine, Cubase always plays back at full volume. I.e., the Windows volume setting is ignored - unless it is completely shut off. That means I have to use Cubase's master volume fader to adjust playback volume. But I don't want to, because its setting to an ideal level is part of project information which I don't want to change.
Specs:
- Windows 10 (1803)
- Realtek High Definition Audio
- Cubase 9.5.30
- Cubase settings:
- Generic Low Latency ASIO Driver
- Release Driver when Application is in Background
