Acer Chromebook 317 audio only in headphones

Hello, I have an Acer Chromebook 317 CPU Intel N5100. I installed windows according to the instructions. I bought a sound license. I installed it. The driver has been installed, but the sound only works in headphones. It doesn’t work in the speakers.

Switch the output device to speakers

of course, I did this and still no sound from the speakers. Has anyone installed Windows 11 on an Acer chromebook 317? Did he have any sound problems?
Maybe it’s a problem with the Windows 11 version? I have the latest version.

I tested the second, identical model of the Acer Chromebook 317 laptop but with the N5100 processor. I bought the drivers on the Coolstar website. The same problem. No sound from speakers. Sound only in headphones. How to get money back from coolstar?
