Hi, I'm running my hackintosh using my TV screen. I used to use MonitorControl to change my pc screen brightness. But it can't change my TV volume. On windows, I can change it normally.

Now my question is, can we somehow add CEC capability to macOS, so that we can control our screen's speaker easily?
