Hi,
I just upgraded from a Focusrite Scarlett and I find this behavior odd - when I lower the monitor knob, it also lowers the headphones volume.
I am using both headphones and speakers when recording/mixing, but also when I am using my desktop day-to-day.
I would like to have a separate volume control for speakers and headphones. I expected that monitor knob controls only the line output, and headphones knob controls the, well, headphones.
It would be really impractical to have to unplug the speakers every time I want to use headphones only.
Is there a way to do this - have my speakers silent while I am using my headphones?
