Describe the issue

Volume control is not working on my Iiyama G-Master GB3466WQSU monitor.

Expected behavior

I would like to control sound volume in MonitorControl App.

Anything else?

Does the app have some logs/raport? Can I send it to you ?

This seems to be a monitor specific issue. You can try alternate apps like m1ddc to see if that app can change the volume. I'll convert this into a discussion so others with a similar display can chime in. Thank you!
