Developer CoolStar created custom SST audio drivers to solve this exact problem. These drivers restore full sound functionality to many Intel-based Chromebooks.
This method puts Windows into , allowing test-signed drivers to load.

Installing Windows on a Chromebook is a great way to repurpose old hardware. However, getting the internal audio to work is historically the hardest part of the process. For many Intel-based Chromebooks, the audio driver is the essential piece of software required to get your speakers and headphone jack working.
Note: A more permanent solution involves self-signing the driver with a test certificate or using a boot loader like rEFInd to keep signature enforcement disabled.
Always back up your system before installing any kernel-mode driver.
The driver itself is generally considered safe if downloaded from the correct source. However, it modifies low-level system functions. Use at your own risk.
If the system displays a "No Audio Output Device is Installed" error after a clean reboot, follow these validation steps: Verify Driver Binding in Device Manager Update Audio drivers in Windows - Microsoft Support
