Volume control thru DDM.exe
I am looking to control my display's built-in speakers (S2722QC) via DDM. I have DDM 2.3.1.16 installed. Does this DDM version have volume control exposed?

Nevermind, I figured it out.
I found "VCP:SpeakerVolume "in the SaveDiagnosticReport I created. I was having trouble figuring out the opcode. It is 62. The following commands manipulate the volume through the DDM cli.
ddm.exe /ReadControl 62
ddm.exe /IncreaseControl 62 01
ddm.exe /DecreaseControl 62 01
ddm.exe /WriteControl 62 0D (sets the volume to 13%)
Now, can we have this feature exposed to the DDM GUI alongside the Brightness / Contrast controls?
