Bootcamp Windows 10 on MacBook Pro 2011: Overcoming Audio Issues

When trying to install Windows 10 on a MacBook Pro 2011 using Bootcamp, many users have encountered issues with audio not being recognized by the operating system. Despite having multiple UEFI installations on their device, none of these OS's have any problem detecting the HD audio controller. For those who are still struggling to get audio working on their Windows 10 installation, fear not! After four years of trial and error, I've finally found a solution that works.

The key to getting audio working lies in understanding how Windows 10 handles DSDT (Differentiated System Description Table) tables. Unlike macOS and Linux, which disregard root bridge definitions and can allocate PCIe devices freely, Windows honors these constraints and will only allocate devices within the reserved 32-bit space budgeted for the notebook's PCIe devices.

One common approach to bypassing this limitation is by passing SETPCI commands from GRUB into Windows 10 or using MM commands in a UEFI shell. However, I was unable to get this method working despite numerous attempts.

After discovering an answer on the Apple Stack Exchange site, I found that the solution lies not in editing DSDT tables or using workarounds, but rather in understanding how Windows 10 handles audio devices when booted in pure EFI mode. The answer provided a detailed tutorial and screenshots to help users overcome this issue.

By following these simple steps, you should be able to get your MacBook Pro 2011's HD audio controller recognized by Windows 10, allowing you to enjoy high-quality sound without any issues.
