Bug ID: 54454
           Summary: Upgrading a Wine prefix configuration after upgrading
                    to Wine 8.1 causes the sound to not work for "wav"
                    files.
           Product: Wine
           Version: 8.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

After upgrading from Wine 8.0 to 8.1 and launching a menu item, the
configuration for the Wine prefix is then upgraded.  The program itself runs
fine, but there no longer is any sound.  It should be noted that the particular
program with this problem is a game program that utilizes the Windows Media
Player functionality to play sounds.

In comparing the system registry files for the previous version, I found that
the media player reference was changed from "wmadmod.dll" to
"winegstreamer.dll".  Following is the text block from the previous system
registry.

[Software\Classes\CLSID\{2EEB4ADF-4578-4D10-BCA7-BB955F56320A}] 1674785220
#time=1d931f40aaaf6e4
@="WMAudio Decoder DMO"
"Merit"=dword:00800800
"WMSDKMerit"=dword:00000100

[Software\Classes\CLSID\{2EEB4ADF-4578-4D10-BCA7-BB955F56320A}\InprocServer32]
1674785220
#time=1d931f40aaae924
@="C:\windows\system32\wmadmod.dll"
"ThreadingModel"="Both"

And following was the updated text block after the configuration was upgraded.

[Software\Classes\CLSID\{2EEB4ADF-4578-4D10-BCA7-BB955F56320A}] 1675650169
#time=1d939d1e8450654
@="CWMADecMediaObject"
"Merit"=dword:00800800
"WMSDKMerit"=dword:00000100

[Software\Classes\CLSID\{2EEB4ADF-4578-4D10-BCA7-BB955F56320A}\InprocServer32]
1675650169
#time=1d939d1e845082a
@="C:\windows\system32\winegstreamer.dll"
"ThreadingModel"="Both"

The interim fix is to manually revise the registry entries back to referencing
the "dll" file for the Windows Media Player.  Once that was done, the program
again produces sound.  I cannot state for sure what type of code correction
needs to be done, but possibly a check of the registry value for the literal
"wmadmod.dll" might need to done before replacing that value with
"winegstreamer.dll"

Regards.
