Describe the bug

I'm running macOS Monterey 12.0.1 and Monitor Control 4.0.2 Build 6965 and my monitor is a Dell U3415W

I can adjust the volume with the keyboard keys as well as from Monitor Control and it shows the changes in the Monitor's own controls. So it looks like it works, however the sound coming out from the monitor's speakers doesn't change. Even if I try to mute, the sound continues to play.

Any ideas what is going on? Thanks!

Steps to reproduce

See above.

Expected behavior

Monitor sound should go up/down as selected.

Anything else?
