On some systems, the system sounds don’t play even if the Sound Scheme is set to “Windows Default”. Also, if you open the Sounds Control Panel (
mmsys.cpl) and click “Test”, the audio may not be played.
However, you may be able to play the C:\Windows\Media\*.wav files (and any other audio file format) separately using Windows Media Player or any other player.
If none of the system sounds files play in Windows, it’s due to a missing “

- Go to the following branch:

- If you’re using Windows 64-bit, make the above modifications in the following registry key as well:
- Exit the Registry Editor.
REG file to automate the above setting
Windows Registry Editor Version 5.00 ;For Windows 64-bit [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32] "wavemapper"="msacm32.drv" [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32] "wavemapper"="msacm32.drv"
Windows Registry Editor Version 5.00 ;For Windows 32-bit [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32] "wavemapper"="msacm32.drv"
wavemapperentries show up in the “Codecs” tab.
Also, make sure that the digitally signed Microsoft Sound Mapper file “
msacm32.drv” exists in
C:\Windows\SysWOW64 directories. If it’s missing, run the sfc /scannow command.
Windows should be able to play system sounds for each event — e.g., empty recycle bin, low battery alarm, etc.
