Certain 32-bit applications not playing event sounds?

If you ever messed with event sound settings on XP x64 (Control Panel->Sound and Audio Devices->Sounds), chances are the new sounds you've set are not playing for certain 32-bit applications. It seems settings are not written in registry under HKEY_CURRENT_USER\AppEvents\Schemes\Apps in a consistent way compared to default settings. Certain sub keys of the keys representing events, eg. AppGPFault, Minimize may not have the default value of type REG_EXPAND_SZ and the full path to the WAV file if residing in C:\Windows\Media.

For example, you set Minimize event to play the provided Windows XP Minimize.wav. By default, this event doesn't play any sound. The .Current key may be updated with default value of event sound file name and type REG_SZ and similarly another key may be created representing that the setting applies for particular sound scheme. But for consistency with the way default settings are done, it should read %SystemRoot%\media\Windows XP Minimize.wav and the type should be REG_EXPAND_SZ, both easily altered with Registry Commander.

Equivalent value in .theme file should therefore read %WinDir%media\Windows XP Minimize.wav.

TBH, I've no idea how many applications even have a problem with not having full paths in the first place, I really only noticed the problem with 32-bit Mozilla based web browsers like Firefox 52.9, Serpent 52, Mypal 68. 64-bit versions, where available, are OK.

Edit: Actually, Mypal 68 still doesn't play certain event sounds, eg. minimizing and maximizing.

Windows 10 always writes full path to the sound file.
