Acer Chromebook 514 Touchpad and Audio doesn't work

I have problem after installing windows 11 on my chromebook. I downloaded all drivers from coolstar for this version of chromebook (intel i3-1115G4) and my audio and touchpad doesn’t work. In device manager I have Chromebook Synaptics RMI Touchpad not working, Audio Multimedia Controller and ten unknown devices.
Can you help me?
Thanks in advance.
