Missing Audio Driver

Model: Chuwi Mijabook
All of a sudden my audio driver disappeared and I’m not able to activate it’s audio. Can someone help me where to find a audio driver?

Hello, please provide the serial number and model number on the back of the machine, thank you

So I don’t know which one is the serial number or model number but here are the numbers at the back of the laptop

These are the numbers that I saw. Thank you

Sorry, there is no driver installation package for this moment, only the system, you try to reinstall the system, thank you
