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.

er-9/

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_man
ager05.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.

Double post, sue me. Ok, another possible fix is to install the standalone
player. Hopefully at the time youre reading this (if this msg is archived)
this version will be current.

Solution #5 Install Standalone Player

You might want to refer to this thread for more detail on some of the other
Java stuff that may have to be reinstalled also:

By the way, if ANY of these fixes helped you solve this NO AUDIO problem,
please post which one worked for you...

YOU ROCK beezlebob666.

CCleaner took out a corupted flash file and all worked!!! Follow instructions,
if you closed a youtube video and it corrupted, example you shut down computer.
Ccleaner removes it and youtube works again.

Nothing seems to work!

I checked the registry key to see that "wavemapper" key was there. I
downloaded CCleanner and ran it to clean out my cache as well as using it to
unistall Flash 9 (and reinstall). The fore-mentioned link to Flash 7 is now
gone to I couldn't try that. I downloaded and installed the K-Lite Codec, as
well as the stand alone Flash player and still no audio!

I have sound everywhere else; I even checked my own website where I have
streaming Quicktime and there is sound. For good measure I even uninstalled an
reinstalled my audio drivers to no solution.

While I have a 5.1 surround sound card plugged in, the system for some reason
does not "see" it. Instead I am using the surround sound system and drivers
off of the main-board.

Any other solutions to this problem?

Resolved my no sound issue by using the Flash Uninstaller to remove Flash
Player 9, rebooting and then installing Flash Player 8. Now I have sound in
Youtube. Not sure what has changed between 8 and 9 but I imagine one day I'll
be forced to upgrade, but hopefully the issue will be resolved.

For Mac OS, the following tech doc is most likely to help:

For everyone who has tried all of the above 5 solutions and still cant get it
to work under WINDOWS (XP) try this?.

All AC97 sound systems are capable of surround sound.

It seems that by default if you have enabled surround sound then WINDOWS
mirrors most stereo sounds to the surround speakers.

It also seems that the latest version of FLASH (I tired 9 and 7) is surround
sound aware and thus doesn?t have its stereo sound mirrored to the surround
speakers.

I found that in my sound card utility (c-media) I had surround sound enabled
(4 speakers). The sound test in that utility only played sound in the rear 2
speakers. Unplugging the stereo speakers from the surround port and plugging
them into the stereo headphone port and using the utility to configure the
system for only stereo speakers I found I could then get sound in FLASH files
and online (youtube) again :))

the solutions above didn't help :(

I've noticed, that anytime I visit youtube, there is created a file
"sounddata.sol" in folder ..\macromedia\flash player\# shared objects\

i've opened it in notepad - it says "4TCSO  soundData volume
mute
" (so no wonder there is no sound :|)

I deleted the file - but it is created again when i visit youtube. I tried to
be smarter, changed "mute" to "on", but when i visited youtube it was replaced
again. I changed file properties to read only - then it created another file.
oh, i have the same thing with myspace :(
I'm getting really frustrated :(

anyone can help?? pleaaase?

Hey Beezlebob, thanks ever sooooo muchhh, it was the CCleaner that fixed it for
me. Just followed your instructions and it was done. :grin;:music;
So even though I got Flash Player 9, You Tube works fine now for me.

Strangest configuration I ever saw, but it works...

Yeah, I've got the AC'97 surround sound system: I have the the center,
sub-woofer and back speaker connectors in the back of the computer, and my main
front speakers connected to the front panel!

Now I have all my Windows sounds back as well.
Thanks!:grin;

Just wanted to thank you for posting this link. I'd tried EVERYTHING to get
the sound to work on my mac and this article finally showed me how to fix it.
I was literally pulling my hair out, so thanks again!

Hi i have tried all of the suggested solutions and i still have no sound!!!

Sound is fine on windows media, just not on youtube and other online video
players.

First (when it went wrong) i could only hear the sound very faintly out of one
speaker, now there is no sound at all. But as mentioned there is sound on
windows.

Can any one help. Any ideas? In LAMENS terms (directions) if poss. Im not that
knowledgable on pcs.

Thanx

I too had NO SOUND in Flash players. I just finished building this computer
for my wife. Installed late at night. Not many lights on. Keep this in
mind...

Yesterday I had a sound problem and had to adjust my surround sound to get
ANYTHING, Had to go to 4 speakers even though I only had 2. Hmmmmmm.

A couple of the suggestions talked about the Flash , Stereo / Surround Sound,
and AC97 audio devices.

After reading these posts I started the Free Napster [Flash] player and went
back to my surround sound (Clicked on the little Xear 3D emblem to launch) and,
while playing a 4 minute song, messed with the settings. Heard NO SOUND on 2
speakers, and Only 3D sound on 4 speakers. No sound from the 4 minute song.

Checked where I plugged the Speaker cable in. It was NOT in the pretty green
hole. Plugged the Green Plug into the Green Hole - ALL SORTS OF MUSIC NOW!!!!!


Problem Solved!!! I had plugged the cable in to the computer at
night...Into the WRONG hole. SO, the Surround Sound was telling the system
that I had 4 speakers, and Flash wanted to ONLY go to stereo, which the
Surround Sound was routing to non-existent speakers.

I have only been building computers since 1993. You would think I know better
by now, eh??

Anyway , for those having problems, perhaps your speakers are not plugged in
correctly or your surround sound is not configured correctly.

As I found out, Not Everything is a driver fault. As a tech with 20 years of
PC experience I have seen my fair share of Operator error - Now I are one :-)
