Record & Playback volume move together

Does anyone know how to stop record and playback volume sliders from moving together? I know it can be done because I’ve done it before but can’t remember how. I’ve looked but can’t anything so any thoughts would be appreciated.

I suspect the reason for no replies, is because no-one knows how to make the record and playback volume sliders move together.
I presume that you are referring to the playback and record sliders in Audacity’s “Mixer Toolbar”

How are you moving the sliders?
Which version of Audacity are you using?
Which version of Windows?
