Can't Use Crtl + Volume up/down as hotkeys

[ManabBala]

What workfow do you want to improve?

I Used a audio switcher before with my windows 10 where i set hotkeys as Crtl + volume up to my speaker and volume down to head phone and instantly i could tweak my volume level for each source(windows persist the previous audio level for each source).

How to make it better?

While i am trying to set the hotkeys one notification popup saying hotkey can't be set (exception). Could you please add this capability as i am used to my workflow. Thanks

Any alternative?

no
