Re: [PATCH 0/14] MR2636: wine{alsa,coreaudio,oss,pulse}: Move AudioSessionManager into mmdevapi.

[Davide Beatrici (＠davidebeatrici)]

```c
../dlls/mmdevapi/audiosessionmanager.c:159:40: error: 'AudioSessionManager2_Vtbl' defined but not used [-Werror=unused-const-variable=]
  159 | static const IAudioSessionManager2Vtbl AudioSessionManager2_Vtbl =
      |                                        ^~~~~~~~~~~~~~~~~~~~~~~~~
```

I will move `AudioSessionManager_Create()` into the commit that implements the interface.
