Before opening the issue, have you...?

Searched for existing issues
Looked through the wiki
Updated MonitorControl to the latest version (if applicable)

Describe the bug

Brightness works well. Volume does also until the volume level reached 0%. If I raise volume again (volume levels >0%) there is no sound. MacOS and LG OSD shows the correct sound level but the monitor stays silent. ./m1ddc set volume 15 also set the correct sound level but the monitor is still quiet.

I restart working after I suspended the MBP ... until the sound level reached 0% again.

Monitor is connected via USB-C

Steps to reproduce

Decrease sound to 0%
try to raise volume level again

Expected behavior

raise volume higher than 0%

Anything else?

No response

Hi, please try Enable Mute DDC command (you'll have to enable Advanced at the bottom of the General tab in Preferences) and please let me know if it helps! Thank you!

After enabling that option everything works as expected.
