            Bug ID: 47437
           Summary: Final Fantasy XIV 5.0 crashes on startup when using
                    xaudio2_8.dll
           Product: Wine
           Version: 4.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: xaudio2
          Assignee: wine-bugs at winehq.org
          Reporter: achurch+wine at achurch.org
      Distribution: ---

When starting Final Fantasy XIV 5.0 (Shadowbringers), after logging in through
the launcher, the game program (ffxiv_dx11.exe) immediately aborts with an
"unexpected error" dialog when the Windows version is set to Windows 10 in
winecfg.  The error results from a crash in FAudio, called via xaudio2_8.dll,
trying to read through a clobbered pointer value.

FFXIV apparently chooses an XAudio2 API version based on the reported Windows
version; setting Windows 10 causes the game to load xaudio2_8.dll, while
setting Windows 7 causes it to load xaudio2_7.dll.  The game starts normally
(and audio works properly) in the latter case.
