ERROR: unresolved external symbol PKEY_AudioEngine_DeviceFormat Apparently the order of the header includes matters, and initguid.h must be included first. Let's hope this doesn't break anything on the other toolchains. https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/ceff4e2d-8f63-4ab6-b09b-fdac65d62a80/pkeyaudioenginedeviceformat-link-error?forum=windowspro-audiodevelopment
