Adobe Flash No Sound WaveMapper Trick

Occasionally users may encounter problem that there is no sound output from the Windows system especially when trying to playback a Flash based contents by installing the latest version of Adobe Flash 9. 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.

    So I followed this but it didn’t work when I tried to make the new file it said it already exists. So i went to Edit-permissions…-advanced-edit the adminstrator- click full controll-ok-apply-apply. Then it should work!

    Hey there,

    I followed the instructions and it worked. Thank you very much. I never leave comments, but I whole-heartedly thank you for the step-by-step instructions. They were very accurate and complete and it worked! I am not a tech-savvy person, so I commend you on good writing!

    Thanks. After a bad virus infecetion I had no sound for all webbrowser. The advice to check the wavemapper reg key value was useful although the name – value was present in the register.

    The problem was actually register permissions. Once I gave permission to allow full control of the register for the admin account – IT WORKED!
