I want to be able to control sound volume in X34P monitor, directly from computer (using DDC protocol). However, it seems firmware in X34P has problem with this. Is there solution to this?
There are tools both in Windows and MacOS to do this, such as MonitorControl or DDCctl I can easily control monitor brightness or contrast but not volume (which is what I want to do most often actually).

Are there more people willing to have it working?

    This is how am I trying it with ddccdl:

    ddcctl -d 1 -v 60
    D: NSScreen #478260293 (3440x1440 0°) 109.00 DPI
    I: found 1 external display
    I: polling display 1's EDID
    I: got edid.serial: #ASMUeGST5VPd
    I: got edid.name: Acer X34 P
    D: action: v: 60
    D: setting VCP control #98 => 60

    ddcctl -d 1 -v 60
    D: NSScreen #478260293 (3440x1440 0°) 109.00 DPI
    I: found 1 external display
    I: polling display 1's EDID
    I: got edid.serial: #ASMUeGST5VPd
    I: got edid.name: Acer X34 P
    D: action: v: 60
    D: setting VCP control #98 => 60
