The symptom is obvious when viewing video clips on online video sharing sites such as YouTube, MetaCafe, Daily Motion, MySpace Video, Google Video and etc. Video can be played back, but no sound, voice, or audio is heard.

There is a general Flash no sound registry fix to solve all driver mapping problem that may exists. But if you don’t want to touch so many registry keys, try the following trick which is also a better solution - direct to the cause.

Flash No Sound WaveMapper Solution

  1. Launch Registry Editor by typing regedit at Run command.
  2. Navigate to the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

  3. On the right pane, and check for existance of “wavemapper” registry subkey, the mail culprit causing Flash no sound. If not found, create a new String value named “wavemapper”, and give the entry value “msacm32.drv”.

    If wavemapper entry is already existed, ensure that its value data is “msacm32.drv”.

Also ensure and verify that the msacm32.drv driver file is existing in C:\Windows\System32 folder. If the file is missing in that location, search for other copy of msacm32.drv in the computer, or copy that file from another system.
