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.

Nope, def did not work..I’ve checked the registries, checked that the drivers are in system32..updated browser,WMP,Java..
..Internet sounds AND Windows system sounds do not work, not quite ‘NO’ sound, but rather high pitch squealing and ‘audio garbage’ .. almost like uncoupled audio..
..if I play media in WMP or winamp, audio works fine, can even stream i-net radio thru winamp..
…and here’s the kicker, this has been an on/off issue for over a year, for me (this is a work machine, and the guy who previously used it had issues, as he d/l’d ‘K-lite codec’), and every now and again, this sound issue arises, only to disappear a somtime later,..possibly after a whole wack of updates..
I definitely get the feeling this is a Microshit problem, as in they don’t want to play nice with anyone they don’t have financial stakes in..cause it always seems to resurface after the monthly Java updates..
COME ON M.S. .. just make something that works, reliably, consistently, without daily updates… THATS MY IDEA!!

I wanted to say thanks to the Admins for their effort to help those of us who have experienced this frustrating problem. I have a few more fixes and how they apply to Vista and 7 64bit.
Check if the file msacm32.drv is present in your Windows system32 folder. If not, copy it from another PC (that has the same version of Windows) and place the file in the system32 folder. This applies to Vista and 7 64Bit but in the SysWOW64 directory which is the folder for the 32 bit programs running on the 32bit virtual machine.
A very common sound problem is an incorrect or missing registry key for msacm32.drv discussed in the preceding.
1.Launch Registry Editor by typing regedit at Run command.
2. Navigate to the following registry key:
For XP and Vista 32Bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
3. On the right pane, and check for existence 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”.
For XP and Vista and 7 64bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32
4. On the right pane, and check for existence 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”.
5. In addition the permissions/security on these keys can prevent your browser flash plugin from
accessing them and preventing sound. Also if you receive errors editing or the key is blank you
need to check the permissions by right clicking on the key and choosing permissions. Choose
Advanced and make sure that the Administrators, System, Users Groups have “Full Control” under
permissions if not select them and click Edit and tick “Full Control” under the “Allow” column.

Such a simple fix, it really works!!! So many other posts on tech blogs give possible solutions to this same problem that I am guessing these steps would resolve. Thanks!!!

I went thru all the tricks above… none helped.
I then tried booting to Ubantu using Wubi (linux) and had a flash player issue there also.
“You keep Windows as it is, Wubi only adds an extra option to boot into Ubuntu. Wubi does not require you to modify the partitions of your PC, or to use a different bootloader, and does not install special drivers. It works just like any other application.”
I uninstalled Ubuntu and now all is good!
I sure hope Ubuntu matures a little bit more, I am almost ready to leave Microsift entirely, for good.

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!
