Summary: WAVE_mciOpen fails to open wav file without write access
                    (from CD)
           Product: Wine
           Version: 20050725
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-multimedia
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When running Zapitalism Deluxe, the wav sounds fail to play from the CD.  With
WINEDEBUG=warn+all, the relevant messages (repeated for each attempt to play a
file) appear to be:

warn:file:CreateFileW Unable to create file
L"D:\lavamind\zap\sound\lavamind.wav" (status c00000a2)
warn:file:OpenFile (D:\lavamind\zap\sound\lavamind.wav): return = HFILE_ERROR
error= 19
warn:mciwave:WAVE_mciOpen can't find file=L"D:\lavamind\zap\sound\lavamind.wav"!
warn:mci:mciGetDriverData Bad uDeviceID

I believe the problem is related to mciOpen attempting to open the file with
write access because of the error 19 (defined in winerror.h as
ERROR_WRITE_PROTECT).  To test this, I mounted a tmpfs over the directory
containing the audio files on the CD and copied all audio to that tmpfs and
added write permissions.  The files were then correctly played in wine without
the above errors.

This bug may be an error in the Zapitalism Deluxe program (asking for write
permissions when they are not needed), but it appears that (on line 392 of
mciwave.c) WAVE_mciOpen calls mmioOpenW with MMIO_READWRITE in all cases. 
Please take that as just a quick suggestion, you are the experts and have a lot
more experience than I.  Just trying to be helpful. ;)
