Lock Audio Level

[NikonPunch]

I use a mixer for all my streaming audio and never have a need to change the audio input level on OBS. However I have tab'd out of a game and without knowing clicked the volume level on OBS and reduced it. Is there anyway to have it lock so you can not change it without going into the menu or having to do something to override it?

This doesn't happen often but it has happened a few times. Thanks for all your hard work!
