Bug ID: 52998
           Summary: xaudio2_7:xaudio2 fails on Windows 1909+
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: xaudio2
          Assignee: [e-mail]
          Reporter: [e-mail]

xaudio2_7:xaudio2 has the same set of systematic failures on all Windows 1909+
versions:

xaudio2.c:1096: Test failed: xaudio2_8.dll:
CreateFX({a90bc001-e897-e897-7439-435500000000}) failed: 8007000e
xaudio2.c:1096: Test failed: xaudio2_8.dll:
CreateFX({a90bc001-e897-e897-7439-435500000001}) failed: 8007000e
xaudio2.c:1096: Test failed: xaudio2_8.dll:
CreateFX({a90bc001-e897-e897-7439-435500000002}) failed: 8007000e
xaudio2.c:1096: Test failed: xaudio2_8.dll:
CreateFX({a90bc001-e897-e897-7439-435500000003}) failed: 8007000e
xaudio2.c:1116: Test failed: xaudio2_8.dll: CreateFX(CLSID_AudioVolumeMeter)
failed: 8007000e

https://test.winehq.org/data/patterns.html#xaudio2_7:xaudio2

The error code is E_OUTOFMEMORY and the failures correspond to the following
formats:
  CLSID_FXEQ27
  CLSID_FXMasteringLimiter27
  CLSID_FXReverb27
  CLSID_AudioVolumeMeter

Strangely enough the test succeeds on Windows 10 1507, 1607, 1709 and 1809
without any visible skip.
So it's as if support for these formats was removed (but that's a strange error
code to say so), or something more must be done to get them initialized
properly.
