In both 2017.2.7.6661 and 2017.2.6.6636 (not checked others) the provided win32 vc140 static libs look to be compiled with AKSOUNDENGINE_DLL defined resulting in AK_DLLEXPORT on all API functions which is not needed for static libs.
This then results in my dll that links the AK libs exporting about 300 AK functions, this may also effect /LTCG optimization as the functions can't be inlined since they are exported.
Thanks,
Tom.
