            Bug ID: 39339
           Summary: Adventure games from Daedalic Ent. (Night of the
                    Rabbit, Edna & Harvey, A New Beginning) have no
                    in-game audio and freeze on new game start - XAudio2_7
           Product: Wine
           Version: 1.7.51
          Hardware: x86

                OS: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: xaudio2

On my system the problem was surfaced by the Xaudio2 implementation in 1.7.51,
the games used to work properly before. It sounds similar to bug #39320 and bug
#39321, except that the proposed patch doesn't help here.

All the adventure games from the developer/publisher Daedalic Entertainment
that use Xaudio2 interface are affected in a similar manner:
- the main menu is missing audio
- when I try to start a new game or load a saved game, the game freezes (100%
cpu usage) as soon as the game is loaded.
- quitting the games from the main menu takes a long time (1-2 minutes)

I reproduced the problem in these games:
The Night of the Rabbit, Edna & Harvey: Harvey's New Eyes, A New Beginning -
Final Cut.
The games load xaudio2_7.dll

Note that almost all these games have demo versions either on Steam or
elsewhere, but those demos are older versions of the games and they don't use
XAudio2.
The only demo (so far) which has the bug is the Night of the Rabbit demo on
Steam (link added to url).

Steps to reproduce the problem in NotR demo:
1. install the demo on Steam. Steam installs .Net 3.5 and MSVC++, they are not
needed for the game, you can delete the installers located in _CommonRedist
before starting the demo.
2. the demo starts with a video (audio works in there). The menu has no audio
with built-in xaudio2.
3. start a new game...the game seems to be hung at this point. It takes 1-2
minutes until the first intro video begins to play. Skip the video <Esc>, the
game screen appears and the game is frozen for good.
4. you can reproduce the long wait before the game completely quits, if you
exit the game from the main menu.
