Bug ID: 35683
           Summary: stereo sound L/R volumes extremely inaccurate
           Product: Wine
           Version: 1.7.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-dsound
          Assignee: [e-mail]
          Reporter: [e-mail]

I noticed this in SoF3 first, then downloaded RightMark3DSound to confirm it.
In RightMark3DSound, position the sound box just one pixel to the left and you
get mostly only sound on the left, same for the right side. If you use it on a
windows machine the sound volumes on each channel are as expected (meaning
entirely different).

Best demonstrated in this video: http://www.youtube.com/watch?v=WKfzNjz0w7s

I only added the asound.conf lines shown at the end of the video, because I
thought it might be 5.1 support weirdness of wine. What they do is to mix the
designated >2 channel PCMs down to stereo sound.

x86_64 GNU/Linux
card: 08:00.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)

Bare alsa, no pulseaudio or other funny stuff. Used empty wineprefix (32bit),
also tried installing MS direct X dlls: no difference.
