Bug ID: 40898
           Summary: Mass Effect (Steam) has no sounds with native OpenAL
                    (except for cutscenes)

The problem sounds similar to bug #40833: audio works in the cutscenes, intro
videos, but not in the menus and in the main game.
The differences are:
- Mass Effect doesn't make use of Xaudio/Xaudio2 but Openal (the game comes
bundled with native openal32.dll and wrap_oal.dll)
- the proposed patch from bug #40833 doesn't fix the problem.

I reproduced the problem with ALSA and Pulseaudio as well.

Possible workarounds:
- force Wine to use the built-in openal32. Audio works with that (the game
recognizes the audio device as 'Generic Software').
- when using the native openal32, edit BIOEngine.ini and change the line in
section [ISACTAudio.ISACT.AudioDevice]
DeviceName = Generic Software

For some reason, the game always tries to use 'Hardware acceleration' for sound
when using native openal32.dll that comes with the game.

FWIW, audio used to work in the game before

openal32: Prefer native version.

Because openal contexts are global per-process, applications that use
    openal will conflict with Wine DLLs that use openal like xaudio2_7 now
    does. Windows does not ship an openal32, so all applications that use
    openal will ship their own copy of it. According to Chris Robinson,
    Windows native openal32 works fine in Wine, so we should just use that
    to avoid the problem.
