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
- Launch Registry Editor by typing regedit at Run command.
- Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
- 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.

Same problem as everyone else – no sound in youtube, but sound works in other programs on computer. I’ve tried all the uninstalling, re-installing of firefox & adobe shockwave, etc. I have that driver in those files…. what else? It was working until yesterday !

I have the same problem indicated here. I don’t have sound coming from my webpage (youtube or any other application in webpage both in IE and firefox) and I also noticed that there is no sound in yahoo messenger as well. I checked all the existence of the msacm32.drv. It was absent so I downloaded the file from http://www.afreedrv.com/drv/download/3052/msacm32.drv
The place in the registry is ok with wavmapper.
One thing I noticed in the control panel>sounds and audio devices>voice tab>voice playback (deaful voice) is empty. There is a dropdown menu and I can see my audio device (Realtek AC97 Audio) but when I select and hit apply and/or OK button and return to the same option, i find the option empty again. I think this is the main reason behind no sound from my webpage. Can you help me fix this problem?
Please email me in the email address provided when i commented in this page just to know if I am being helped or that my comment reaches you.
Thanks,
Amrit.

After trying many, many things it turns out I was just missing this file (the last thing you mention here) msacm32.drv from my Windows/System32 folder. Once I searched and found it elsewhere on my system and copied it into the System32 folder… voila! I now have sound from YouTube and elsewhere. My system sounds are still not working, though.
Thank you so much for this information!
