           Product: Wine
           Version: 1.9.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

module:find_forwarded_export module not found for forward
'xaudio2_7.DllGetClassObject' used by L"C:\windows\system32\xaudio2_6.dll"

I Write a Program for testing xaudio2

#include <Windows.h>
#include <stdio.h>
void CheckMethod(HINSTANCE hin,char name[])
{
    void *func = GetProcAddress(hin, name);
    printf("%sFind %s In XAudio2.6\n", func ? "":"Not ", name);
}
int main()
{
    GUID clsID;
    CLSIDFromString(L"{3eda9b49-2085-498b-9bb2-39a6778493de}", &clsID);//GUID
OF XAUDIO2_6
    HINSTANCE hin = LoadLibrary(L"XAudio2_6.dll");
    CheckMethod(hin, "DllGetClassObject");
    CheckMethod(hin, "DllCanUnloadNow");
    CheckMethod(hin, "DllRegisterServer");
    CheckMethod(hin, "DllUnregisterServer");    
    return 0;
}

In Windows ,It shows that:
Find DllGetClassObject In XAudio2.6
Find DllCanUnloadNow In XAudio2.6
Find DllRegisterServer In XAudio2.6
Find DllUnregisterServer In XAudio2.6

But In Wine (Ubuntu 15.10),It shows that
module:find_forwarded_export module not found for forward
'xaudio2_7.DllGetClassObject' used by L"C:\windows\system32\xaudio2_6.dll"
Not Find DllGetClassObject In XAudio2.6
Find DllCanUnloadNow In XAudio2.6
Find DllRegisterServer In XAudio2.6
Find DllUnregisterServer In XAudio2.6

I find "DllGetClassObject" in xaudio_dll.c of Floder "xaudio2_7"
