Apple officially ended support for the 2012 MacBook Pro with Windows 10 in 2021. The last Boot Camp driver package (v6.0) was designed for Windows 8.1. When you force-install Windows 10, you rely on BootCamp\Drivers\Cirrus\CS4208.inf.
The fatal flaw: The official CS4208.inf contains a PowerSettings section that disables the audio codec’s thermal monitoring. Apple assumed the SMC would handle all thermal events. However, Windows 10’s "Modern Standby" (S0 Low Power Idle) overrides the SMC.
In plain English: Your MacBook thinks it is asleep (low power) while Windows runs it at full throttle. The audio driver receives a "sleep" command, shuts down, and never wakes up.
The verdict: Do not use Apple’s Boot Camp audio drivers for Windows 10 on the 2012 model. They are unsafe for your hardware. macbook pro 2012 audio driver windows 10 hot
