This solution is for WINDOWS ONLY!!! Unfortunately I believe
it is a bug in flash itself as I have read more than one instance
of this same no audio problem occuring on MAC'S and LINUX based
systems as well. IF YOU KNOW OF SOLUTIONS TO THE MAC OR LINUX BASED
PROBLEMS, PLEASE POST THEM IN THIS THREAD.
Description of the problem: Video sites such as YouTube,
VideoSift, Break, Google Videos, Yahoo, and a plethora of others do
not stream embedded audio. Viewing a YouTube video, for example, on
VideoSift.com results in the video playing back with no audio.
However, by going directly to YouTube and playing back the same
video, it appears to work.
THERE ARE SEVERAL POSSIBLE SOLUTIONS.
Problem: You may be missing your WAVEMAPPER driver.
Cause: Wavemapper driver was removed during installation or
updating of the Flash Player. It might not necessarily be Flash
that removes it but apparently something does.
Solution #1: Google "Flash No Audio WAVEMAPPER" for
directions, its been covered a bunch, but basically requires
running REGEDIT and readding the WAVEMAPPER key to the appropriate
location and value in the registry. Its not as difficult as it
sounds.

if your wavemapper key is installed correctly...
Possible Cause: Corrupted or damaged flash content preventing
audio streaming from working correctly.
Soltuion #2: Run CC Cleaner and delete only cached Flash
content. It is a free program, again just google "download CC
Cleaner". This particular solution worked for me.
If CC Cleaner also does not work, the description of your
problem may differ slightly. In my case on several computers, one
day it worked, the next day it didnt. If it never worked, this
would be a logical solution for you. One variation of this that I
have found is to create a new Windows User Account and log into it.
The reason the CC Cleaner method may work better is that the User
Accounts have their own separate cache folders so a corrupted cache
preventing audio playback on one profile will not be available on
the other User Account to cause the same problem. I wont explain
how to do this as the CC Cleaner will work better but if you are
curious, yet again google "create new windows user accounts". I
have also seen this method work on one of my affected computers but
it did not fix the issue on the account I was having problems with.
http://www.ccleaner.com Install
and run it, use it only to remove Flash under the Applications Tab,
Multimedia, Adobe Flash Player. Check it and uncheck everything
else, then hit Analyze then Run Cleaner.
Possible Cause: Missing Codec
Solution #2: Download and install the K-Lite Codec pack.
Again, google it. A CODEC stands for COmpressor DECompressor and is
a way to make audio and video files small enough to be transferred
on the internet. There are a lot of different codecs and if you
want to play back a video that was compressed using a particular
codec, you will need that same corresponding codec to decompress
your media source and view its content. Basically if you dont have
a codec, you cant observe the content of the media. If you have a
VCR and want to play back a DVD, you are out of luck unless you get
a DVD Player. DivX and XVid Codecs are some of the very popular
codecs used on the net, but to get those, I still suggest getting
the K-Lite Codec Pack.

Solution #4: Go back to Flash 7. If it aint broke dont fix
it. This Final alternative is only to be used as a last resort.
You'll have to get rid of Flash 9 and go back to Flash 7. The
really tricky part here is that you have to prevent Flash from auto
updating itself. If you install Flash 7, and hit up YouTube, you'll
immediately get Flash 9+ installed again with the same problems. So
AFTER you uninstall Flash 9 (use Macromedias / Adobes uninstaller,
yet again go google it) make a new text file and name it MMS.CFG,
in the file put this one line "AutoUpdateDisable=1" (without the
quotes) and put it in BOTH your c:\windows\system32 AND
c:\windows\system32\Macromed\Flash folders. This will prevent flash
from Auto Updating to 9+, then have to find some place to download
the old flash 7 installer. I found one here.
http://www.intercomm.com/downloads/Flash7.
Only problem is that most sites will try to make you install Flash
9 and Flash 7 does not work on all sites, but it does on some like
YouTube. DO NOT UPDATE TO FLASH 9+ IF YOU USE THIS METHOD.
You will probably want to IMMEDIATELY go to
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager05.html
after installing Flash 7 and UNCHECK the update feature
I've tried to write this quick little guide at 3AM so Im not
going to take more time to research other ways to fix this problem.
If you have other solutions, such as for MAC and LINUX, or feel
like adding on to something else that I've written here (links
would be useful to the downloads I suggested) or correcting any
mistakes I probably have made, please say so.
One of these solutions is bound to help you. Theres multiple
causes for this no audio problem so there is obviously multiple
fixes.
