  1. You should be able to get the brightness keys working by applying the ACPI patches described in the thread dedicated to that matter in our Technical info/R&D section.
  2. 'don't understand your issue.
  3. Won't work, no support for this type of hardware in macOS.

ok, i tried them all and the only one that gave audio on the laptop speakers and headphones was the layout 77, but only if i don't plug it in fully and it makes strange noises like it has interference.

OMG it's working thanks

Now I have two problems that I have not been able to solve:
1. The touchpad with multi-gestures. But the buttons only work if your finger is pressing the touchpad.
2. The brightness keys on the screen, I could not solve it with the guide that was provided above

I am currently running Monterey
