I had messed around with mm commands in a UEFI shell (The shell provided in the rEFIt package) to no avail* The part that was frustrating to me was that many users like myself have lots of UEFI installs on their 2011 MBP and those OS's have no problem 'seeing' the HD audio controller. I was given the answer from a tutorial only adjacently related -here:Įssentially what we knew was that windows didn't 'see' the correct audio devices when booted in pure efi. If you do not hear the system sound then, you are on mute or your sound card is broken.If anyone is still interested I have found the solution for audio on MBP 2011 Windows 10 UEFI installs - it has taken me 4 years to figure out. Keep Holding until you have hear the "startup sound twice". Lets try to load it manually using Terminal sudo kextload /System/Library/Extensions/AudioAUUC.kext/īased on new information I would suggest following (still trying to find out why your Audio is not loading in the profile.You should have the Īs reported the result is: AudioAUUC.kext is not been loaded?
