Asus C403NA sound drivers

Hello. I need some working drivers for windows10 for Asus C403NA Chromebook.
Can you help me and what price?
Thank you!

Windows is on board only problem now is sound!

In the tutorial for your Chromebook, there is an audio section that shows how to get the audio drivers.

Hi! And Thank you for reply, there are driveres only for 423 model, but mine is 403…so I wonder where I could find them and what price shall be for them?
