Same issue on LG monitor. This worked for me. Don't forget to enable DCC settings for sound and restart the app/Mac.

Some displays do not support DDC volume adjustments. You might want to try alternate apps like BetterDisplay to see if it works better, but if it's a display firmware issue, it probably won't help.
