Add option to keep level 0 channels at 0 for accessibility reasons

[icuurd12b42]

Summary

I just installed this to help with my tinnitus on my left ear.
I set up Chrome to play on my Raptor Headphones, and I set that device's balance to have the right speaker volume to 0 and the left to 50.
The default audio is set to High Definition Audio Device, Basically my room speakers. I browse and watch video on my brave browsers.

The problem is that When you increase the volume for the Raptor Headphone with the EarTrumpet volume control, it Raises the muted channel...

So I basically need to go in the Device's Properties/Levels/Balance to open the Balance Window to set the volume of the right channel back to 0. I actually now leave the Balance Window open and change the volume on the left channel directly there.

The application should leave the muted audio channels alone

Steps to reproduce

There's no such thing as a muted channel. It's just set at level 0, making this impossible to handle without an additional option somewhere. I'll move this to the Discussions area as a great accessibility-themed feature request/idea, thanks!
