hi, guys.

I have same trouble. but this method can remove it in my case.

make new key "HackFlags" as (DWORD 32) type value 0x600 600 as (Hex) in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PnP\Pci\

and reboot.

update:
Sorry. That's right. I made a mistake in expression.
Since this is a "32bit value", the "numbers of zeros" after "0x" has significance.

update2:
It is obsolete to deal with this problem with HackFlags!

Windows Update on Jan/3/2018[KB4056892] might fix this probrem!

You no longer need HackFlags nor Disable Audio Devices!
