Asus chromebook c536e win11 audio problem

hello everyone. I installed win11 on my asus chromebook c536e and I have a problem and I can’t solve it without your help. I’ve installed coolstar’s audio but still have no sound. in device manager I see "!"CoolStar SOF Audio(WDM), two of Maxim 98373 Audio Codec, Realtek ALC5682 I2S Audio.

And how to solve problem with NUMLOCK absence ?:slight_smile:

This is CoolStar SOF Audio(WDM) status in device manager:

This device cannot be started. (Code 10)

{License violation}

The system detected a distortion of the registered product type. This is a violation of the license for the program. Changing the product type is not allowed.

What am I doing wrong
