Summary: wwiionline (Battleground Europe): some sounds are not
                    heard from the players position but from elsewhere
           Product: Wine
           Version: 1.1.8
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: directx-dsound
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When sound set to "hardware", some sounds are not heard from the correct
position. Among these are for instance aircraft engine sounds (yours and
foreign) and gear and flap retraction/extension sounds. Other sounds such as
gunfire are always heard from the correct position.

One of the positions where sounds are heard is the initial spawn point (at
least for airplanes). However, there appear to be more such points, always at
ground level. When one flies close to ground for some time, sometimes he will
hear himself overflying a position.

Soundcards tested: 
1) Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
2) E-mu 0202 USB

To reproduce:
Install wwiionline (download from ftp://downloads.wwiionline.com/). 
Run WW2_sse2.exe (or any other executable) to go to offline training. 
Select a aircraft. Start engines with "e". Increase the throttle until the
aircraft is rolling. Engine sound will slowly fade. Take off (or stay rolling
on the ground..) and fly low over the starting position left to right. You will
hear the airplane passing overhead.

Occurs in all wine versions tested, from 1.1.3 to 1.1.8. OS is Debian, wine
built from sources.
