Question

Hi, so my question is in regards to the volume control. I have the app installed on a M1 Mac Pro, the Mac is connected to an OLED LG TV C3 2023.

The brightness can be controlled from the keyboard and the menu bar, works perfectly.

The volume shows the slider and moves up and down, but the actual volume of the TV is not changing.. that is the issue, could you please help me with fixing this?

I'm using a Logitech keyboard currently, but my Apple Magic Keyboard is on the way, thought I would mention it, maybe that is the issue..

I also thought it could be a TV setting that needs to be turned on..?

My Mac and TV are connected through h a USB-C to HDMI cable.

To summarize, everything works and shows EXCEPT the volume of the TV actually changing.

Most TV-s do not support DDC so volume control won't work. For brightness probably only the 0-50% range works, you need to disable DDC under Settings for the TV to make it work properly.
