How to Adjust Volume Levels Separately for Virtual and Physical Audio Devices?

[originalprod]

Hello,
I use both virtual audio cards and physical audio cards, and I was wondering how I can adjust the volume of a virtual audio device. I want the monitoring output volume to be different from the main audio device output. Is this possible?
Thank you very much!

Separate volume controls for Main and Monitor audio devices will be added in RadioBOSS 7.2.
For now, you can use volume controls in Windows to change per-device volume.

It’s not possible to control it using the Windows volume controls. Increasing or decreasing the volume does nothing, the sliders don’t work at all, except for the mute button in the recording devices section.
I recorded a video showing the issue: https://youtu.be/EIcTn4Yt1sM
