      • 120. Re: Going Crazy: Why No Sound w. Flash 9 in some but not all sites w/ embedded video?

        Hello!
        I have no sound in flash videos (eg. youtube) both in firefox and IE
        I checked the registry, drivers, codecs - nothing works :(

        What I've noticed is that every time I visit youtube, a file "sounddata.sol" is created 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?

          Go to a page with a Flash video on it.
          Click on the video to activate Flash, then right click on it to bring up the Flash menu.
          Click on "Settings", then click the "Advanced..." button.
          This should open a new browser window with the Flash Player Settings Manager.

          Look on the left side, under "Table of Contents" and "Flash Player Help", for "Global Storage Settings Panel"
          Click the "Global Storage Settings Panel" link. This will load the panel on the right side in a Flash object.
          You will find that the "Allow third-party Flash content to store data on your computer" box is unchecked.
          Check that box!!!

          After the box is checked, it should save the setting right away, but I had a little trouble getting it to save the setting. I had to close all open Internet Explorer windows and go back and check the box several times, but finally it saved the setting. Once it did, I had audio in my embedded YouTube videos again.

                I tried the regedit process and carefully followed all the steps but when I double click to import the file, I get an error message stating, "the specified file is not a registry script you can only import registry files". I titled the file missing.reg and then I tried wavemapper.reg. I tried importing from within the registry editor. Please help me! I'm using Windows 2000. Could that be relevant to this problem?

                  The other day this happened to me. I had updated real player and later that day went to watch a video on You-Tube it had no sound. This was driving me nuts as it worked early that day. I was about to give up and try all these suggestions above when I noticed that when I opened You-Tube and clicked on the video the sound was turned way over to the left. I clicked it back over to the middle and sound was there. Some update must have turned the sound off. When I have gone back to You-Tube the setting is still in the middle. Check it first. Hope this works for some.

                    Mike - you're da bomb !!!

                    I got the same problem - embedded videos don't play, directly on YouTube they do - registry was fine, drivers were there, k-lite pack didn't help ...

                    Then I found this option had gone been set to OFF.

                    Now it's clear - when you play an YouTube video embedded on some other site, this site is the "owner" of the flash video, and YouTube is the third party - who tries to store the volume setting, which it can't with that option off.

                    Your hint saved me some more days of getting mad, I suppose - this way it was only half a day.
                    Still enough to throw something at Macromedia.... !!!

                    Best regards, and many thanks again - Peter

                      Guys, this is the thing that worked for me. Same problem, couldn't hear imbedded YouTube videos on anybody's site. All other videos were fine (YouTube on the YouTube site, GoFish, Vimeo, MySpace). Only the imbedded YouTube ones. This was easy to fix with the instructions given by MikeBomb. Man, I owe you one of these (make that 2):

                          looking for a solution for over a month. No sound from any flash application.

                          I've tried the registry fixes, both manual and using the k-lite pack, resetting my sound drivers to their settings they need, downgrading and upgrading flash player, everything.

                          I'm using a sony vaio vgn laptop, with windows vista ultimate. this is really getting on my nerves, this cuts out a ton of content over the net.

                              I encountered a similar problem upon downloading Adobe's flash player 9. Unlike the majority of individuals who have posted complaints on this forum, NONE of the sound on my PC worked. AT ALL. PERIOD. So, I searched on here to find the solution, had an idea, and apparently it has paid off. Try adjusting your PC's audio hardware settings. All I did was test my digital output, and all of a sudden, I could hear again. It was like waking from a nightmare. I use an Acer Aspire 3050 notebook and run Windows Vista home basic, for everyone's reference.

                              Just wanting to offer a hand to my fellow vexed and baffled users,

                                          I tried all of the same things and even purchased a new sound card and that did not work either. My problem was that I did not have sound on youtube only. All sound worked great everywhere else. After banging my head and trying all of the different "fixes", I experimented on my own. I am running Windows Vista Home Basic upgraded from Windows XP. Someone mentioned that when they made another USER ACCOUNT that they were able to get sound on youtube but only with that user account and not their Administrator account. I created another user and sure enough the sound worked. Then began a long process of switching between accounts and checking files to see what was different. This is what I found. First make sure that you are able to view HIdden Files and Folders. This is done by selecting Start Menu, Computer, Organize, Folder and Search Options, View, Hidden Files and Folders then selecting Show Hidden Files and Folders. Click Apply. Click OK. Now find the folder for the current user. Mine is located right under the Desktop icon in Windows Explorer. Open that file. Click on AppData, then Roaming, then Macromedia, then Flash Player, then Macromedia.com, then Support, then Flash Player, then SYS. You should now have a list of all the websites that have used the flash player. On mine there were 2 entries for youtube. One was #www.youtube.com and the other was simply #youtube.com. I checked the same place on the User Account that worked correctly and guess what? No entry for #youtube.com so I deleted that entry on the Non-Working Account. I then followed the same path except instead of choosing Macromedia.com I chose the #SharedObjects file and deleted all files that had any reference to youtube. I hope that if you are as frustrated as I have been over the past few months that this finally fixes your problem.

All you need to do is to open registry editor by going to Start menu, Run, typing regedit and then Enter. After that, in the registry editor, walk yourself through the tree in the left pane, till you reach

                                            My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

                                            And then on the right pane, right click and click on New, select String value, enter "wavemapper" (without quots of course), ENTER, type "msacm32.drv", ENTER.

                                            Close the editor. No need to restart. Video on Google and YouTube et al would work fine now.

                                            Thanks to the member who pointed out the key. I just mentioned the procedure.

                                            Have a nice day!



                                            That solved my problem straight away. I've had no sound for about 3 months in flash, and could not figure out why. I can not thankyou enough

                                              OK people - listen up. This is the fix for Windows and I suspect Mac and Linux too.
                                              Make sure that your green speaker plug is stuck into the green hole. Don't plug it into the blue hole. That is the wrong hole.
                                              Depending on your sound card or chipset, you should get a new device aquired option dialogue when you make penetration. Select the front panel (which turns into line out) or line out.
                                              Line out is where system and browser sounds are sent.

                                                Make sure that your green speaker plug is stuck into the green hole. Don't plug it into the blue hole. That is the wrong hole.
                                                Depending on your sound card or chipset, you should get a new device aquired option dialogue when you make penetration. Select the front panel (which turns into line out) or line out.
                                                Line out is where system and browser sounds are sent.

                                                exurber I could just hug you.

                                                After two months of searching and trying all sorts of thing you fixed it for me. This has happened to me twice. Suspiciously, both times I had unplugged the computer to rearrange the room and when I put it back together the flash sound didn't work.

                                                The first time I called the computer tech to the house and he fixed it in about 5 seconds. Then he said he wouldn't let me pay him since all he had to do was plug in the speaker. Remembering that, I have made sure that all the plugs were pushed in a hundred times. However, I didn't think that the plug might be in the wrong color. They do look alike until you use a flashlight to see.

                                                Thank you sooo much. I was thinking I'd have to call the tech guy again. I'm so glad you fixed it and I don't have to look like the idiot I am.

                                                      ok ppl, ive got a solution that worked for me without the regedit.

                                                      login as admin and check if u have sound on youtube. it's odd, but i had sound.
                                                      after that just create a nem login for windows with admin previlege and voila!

                                                      it worked?

                                                        Unbelievable. So I have been having the problem since updating to Flash 9, and I guess I can somewhat understand why Adobe isn't too hot on addressing this problem considering it is my own damn fault. I tried everything in this forum "Softwarewise" that I could do, but the problem ended up being with my speaker ports. Here's the thing, I have 5.1 surround, and for some reason the way I had it configured before worked fine, but when I upgraded to flash 9 it became a problem. I didn't think to look at my speaker configuration because it worked before the upgrade. I figured out that the headphone port worked fine, I had sound on everything as long as I was using the headphones. Here's the funny part, I reconfigured my speakers and they didn't work STILL, and I couldn't figure out why, because it should be working fine. Meanwhile sound was still coming out of the headphones, frustrated I threw the headphones at the printer they came unplugged and I had sound in my front speakers! Ha, I am such an IDIOT! I forgot that the headphones cut off the front speakers when plugged in, anyway, everything works fine now. I also think that this is only a problem with people using the REALTEK 97 DRIVER, with Soundblaster Speakers, the colors don't exactly match up, and for A.D.D. idiots like me it's a problem. I hope that me being an idiot helps some other guy.


                                                        OMG!! lol thanks a lot! :P

                                                          I've been having the 'No sound in flash player' problem and I think I may have found a solution, at least it worked for me. I actually found this on another forum and the solution is for XP users I believe.

                                                          When I would check my sound and audio device properties, it actually said that I had no audio device. And for some odd reason, under the sound tab and voice tab all the devices were set to "Modem #1Line..." The dropdown menu in these fields did not allow for any other choice. So as per the other forum, I proceeded with:

                                                          Start > Control Panel > Administrative Tools > Services > Windows Audio. Make sure "Windows Audio" service is running. If it's not, right click on this service and select "start".

                                                          Then I went back to sound and audio device properties and switched all the "Modem #1 Line..." back to the proper device as it was now available in the dropdown menu. Now I have sound in youtube and any other flash related sites.

                                                          Hope this helps.





                                                          This was THE solution for me. Thanks.

                                                            Didn't read the whole forum. I found what my problem is. The sound driver of "Realtek" comes with some sound effects. Turn the sound effect to "room" (not "living" room or any other room) and everything goes where it belongs! Generally I think you shoudn't have problems with Adobe or Microsoft (ha! what I said right now!).

Restart the Media Player and the sound should work for you.When I refreshed the media player it prompted me to upgrade and I did. I don't know if the sound max change did the trick or the upgrade but now I have sound on youtube. I tried flash player 8 and it did not work I could not get flash player 7 to load. After I made the media player change I reloaded flash player 9 because I did not have anything due to loading and unloadingseveral. So now I'm running flash player 9 and getting sound from youtube so it can be done!!
                                                                    so if you want to do exactly what I done do this: uninstall flash 9 then do this: Windows Media Player - Tools - Options - Devices - Speakers - Properties - Audio Device to Use: Select the SoundMax Digital Audio from the pull down menu and Apply. Restart the Media Player . If it prompts you to upgrade media player then do so. Then reinstall flash 9( this is done easily by going to youtube and if you dont have flash 9 it will tell you so and give you a link to the down load) this corrected my problem so I hope it solves your issues. I though I was completely out of ideas beforeoI tried this . I joind this forum just to post this because I know how a pain in the but this can be ..... good luck

                                                                            • The installed audio driver may be outdated.
                                                                            • The default device for sound playback may not match the installed audio card.
                                                                            • The Windows system registry may be missing key entries for a Microsoft codec named 'WaveMapper'.

                                                                            Solution 1: Update Audio Drivers.
                                                                            To find the manufacturer and driver version of your system's audio hardware:

                                                                            1. Select Start > Run.
                                                                            2. Type dxdiag in the Open text box.
                                                                            3. Select the Sound tab
                                                                            The device name is listed under the Device category.
                                                                            The driver date and version is listed under the Drivers category.

                                                                            To update the device driver, find the website for the manufacturer of your computer. Search for and download the latest driver for your audio card. In some cases it may be necessary to obtain the driver directly from the audio hardware manufacturer.

                                                                            Solution 2: Confirm that the default device for sound playback is correct.

                                                                            1. Select Start > Control Panel or Start>Settings>Control Panel.
                                                                            2. Select Sounds And Audio Devices.
                                                                            3. Confirm that the default device matches the audio hardware installed.

                                                                            Solution 3: Check the WaveMapper sub key in the Windows system registry.

                                                                            WaveMapper processes .wav sound files in Windows. If it is missing from the system registry, then audio will not play back using Adobe Flash Player.

                                                                            To confirm that the WaveMapper sub key is in the system registry:

                                                                            1. Select Start > Run.
                                                                            2. Type in regedit in the Open text box.
                                                                            3. Navigate to the following registry key:

                                                                            HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32

                                                                            4. On the right panel, check for a sub key called wavemapper.
                                                                            5. If it is missing, right-click on the right panel and select New String Value.
                                                                            6. Name the new string value wavemapper
                                                                            7. Right-click on the new wavemapper string value and select Modify.
                                                                            8. Add the Value data msacm32.dvr

                                                                            This information is also documented on the Adobe Support Site for Flash Player
