           Summary: Everquest 2 Extended crashes in DSOUND_PrimaryOpen
           Product: Wine
           Version: 1.3.2
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com


On my PC, I booted into Windows, installed EQ2, booted into Ubuntu 10.04,
and then did
  rm -rf .wine
  sh winetricks gecko
  sudo mkdir /media/win
  sudo mount -o ro /dev/sda1 /media/win
  cd ~/.wine/drive_c
  mkdir ProgramData
  cp -a "/media/win/ProgramData/Sony Online Entertainment" ProgramData
  cd "ProgramData/Sony Online Entertainment/Installed Games/EverQuest II
Extended"
  wine EverQuest2.exe

This crashed fairly quickly with

Unhandled exception: page fault on read access to 0xb515e5d0 in 32-bit code
(0xb515e5d0).

Happily, commenting out line 235 in dsoutput.c worked around the crash
and let the game play:
