Same issue with 4.2.0 using a Dell S3423DWC on Mac OS 14.4.1 with an MBP M2 Max via USB C / DisplayPort.

The volume control shows up, but it stays on full volume.

Sadly not all displays support DDC volume control and some displays support it on some ports only. You can try alternative apps like https://github.com/waydabber/BetterDisplay, https://lunar.fyi or m1ddc to check whether this is a generic DDC control issue or a MonitorControl specific problem.
