Possible to control the mute from the command line?

[hagak]

I can control the mac mute status via:
"/usr/bin/osascript -e set volume output muted true"

however this of course does nothing if the audio output device is a monitor. I do have the keyboard controls working with BetterDisplay and DDC which is great. However I have a case where i want to programmaticly control the volume and was wondering if their is a way to trigger the MUTE function in Betterdisplay?

You can leave set the app to leave the mute key to the system's native mute (macOS can mute digital outputs). But the scriptable mute (via CLI) is meant for DDC mute control which won't work if the display is not DDC compatible.

So my display is DDC compatible. If i set the mute key to system native it does not mute any audio going to the display. The mute key with Betterdisplay works as expected. What I am looking for is a way to mute using DDC via a scriptable interface.

[waydabber]

In that case simply use the betterdisplaycli set -n=DISPLAYNAME --mute=on command with betterdisplaycli installed and the app running (or use the toggle command to toggle it, get to get the current state).

Thank you that is exactly what i was looking for, not sure why i did not find it in my searches.
