Flash Player 11.8 sound problem

Why  Flash Player from version 11.2  upmix stereo sound to all channels  will be this sometimes fixed or still need to use 11.2 version.

This change in behavior is related to our shift to the newer Windows CoreAudio subsystem. 
The latest Flash Player 11.8 Beta includes an optional flag to revert to the older Windows WAVAudio subsystem, which should resolve the problem.
To change this behavior, you'll need to modify the MMS.CFG file with a text editor.  You can find the locations of mms.cfg for your system on the link below:
http://help.adobe.com/en_US/ActionScript/3.0_ProgrammingAS3/WS5b3ccc516d4fbf351e63e3d118a9 b90204-7c95.html
Once you've located and opened MMS.CFG, you'll need to add the following line, then restart your browser:
UseWAVPlayer=1
Please let me know how this works for you.
Thanks!

  • After installing Flash Player, I lost sound on Youtube and other sites.  How do I fix it?

    After installing Flash Player, I lost sound on Youtube and other sites.  How do I fix it?  I still have sound on some apps.

    To help troubleshoot we'll need the following system information:
    Operating   system  
    Browser  
    Flash   Player version
    When reporting issues with video or audio, it's also helpful to get your system hardware and driver details.  Instructions for finding this information can be found here:
    Windows  
    Mac
    Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player.  I recommend trying both of the links below to see how they perform.  If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing.  You can verify the use of HTML5 by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the context menu.

  • Adobe Flash Player / HP Solution Center Problems!

    Hello
    Last night everything was working fine. Until I installed the latest Flash Player 10.1.53.64 RC7. Upon reboot my HP Solution Center was corrupted triggered a pop up error and tried to get me to reinstall it. I did a restore back to earlier in the day and proved it was Adobe Flash Player. My HP Solution Center then worked great. Tried installing the latest Adobe Flash Player again and same problem. So I did another restore and everything is working great still. What conflict or what could be causing this bug in Adobe Flash Player 10.1.53.64 RC7 and HP Solution Center? Are you working on this and will there be a patch soon? Are you aware of this conflict?
    I am running indows XP Pro SP3 and my printer is an HP C4580 Photosmart. This same problem also happened on my Wifes Laptop running Windows Vista Home SP2 using the same printer. Very frustrated here.

  • Flash player 10 sleep/standby problem

    Since i've installed flash player 10, when I have websites up
    that use the flash player such as hulu.com, veoh.com, etc. it
    causes my monitor to not automatically go into sleep mode and my
    computer to not automatically go into standby mode. After the set
    amount of time, my monitor will begin to go into sleep mode, but
    then power back up, and this only occurs when im on a website that
    uses flash player. I also tested to make sure it was flash player
    10 that was the culprit by using the flash player uninstall, then
    reinstalling flash player 9 to see if that would fix the problem,
    which it did.
    While some may say, "why not just close the websites before
    you leave the room.." I tend to fall asleep while watching tv shows
    on hulu and other sites (dont have tv in bedroom), I would like for
    my computer to be able to go into standby on its own, and have my
    monitor go into sleep mode on its own so that I conserve
    electricity.
    Extra info in case it matters: im on windows xp and I use
    firefox

    Thanks for your reply.
    The issue not related to AS 2, application running on flash player 10.3 in all browsers but updated flash player 11.1 getting problem.
    "AS 2 code .SWF file run on Flash Player 11.1.102.55". this is true/false ?
    please guide me about this issue.
    sorry about my english.

  • Flash Player playing multiple sound feeds at once...even when browser is closed

    I recently updated my Flash Player to 11.3 (most recent version). When I go to a site which utilizes Flash (e.g. YouTube), I will start the video, and then about 10 seconds later, I get multiple sound feeds at the same time. They all sound like commercials, or tv channels. Even when I close my browser, the sound continues. When I open my sound mixer, there is a "program" listed of "winrscmde" which is playing the various audio channels all at once. When I go into the task manager, "winrscmde" shows as a svchost.exe *32. When I stop that service the sound stops. It will start again when i access a flash site. When I uninstall Flash Player 11.3, this stops.
    I'm running Windows 7 - 64 bit with latest updates. IE 9.0.8112.16421
    Any help would be appreciated.

    Well, I think I fixed the problem.
    I found this topic:
    http://www.bleepingcomputer.com/forums/topic442928.html
    About the second post down, the poster recommends downloading TDS killer as winrscmde.exe is disquised as svchhost.exe in the \windows\system32 folder (you have to click on "Properties", then "Details" tab and check the original filename...if it's bogus, it'll say winrscmde.exe as the original name).
    I also ran the aswMBR program as well as FixTDSS (http://www.symantec.com/content/en/us/global/removal_tool/threat_writeups/FixTDSS.exe).
    That seemed to fix the issue. Just reinstalled Flash and don't get the same issues. The svchost.exe in the \windows\system32 folder is legit!
    Hope that helps anyone else with the same problem.

  • Flash player delivers no sound

    I get sound with realplayer and windows media player. My speakers are plugged in and sound is not muted or turned down in any way. I get audio in all situations except when attempting to use Adobe flash player......even un-installed and re-installed. help please

    I have sound coming out of my Mac's speakers rather than
    through my audio interface. Only happens with flash audio/video
    players, and I get the same problem whether in Safari or Firefox.
    The Flash audio stream just isn't behaving properly.

  • Flash Player 10 and audio problems

    Hi all,
    this is my first post here. I have a problem with the audio
    of some videos in a website. The videos have been made with Flash
    Slideshow Maker Professional. With Flash Player 9 everyhting is ok,
    the audio is good (the source is mp3), but since I installed Flash
    Player 10 it's impossible to listen to the audio. There are a lot
    of gaps and rumours, the sound is discontinuous and "damaged".
    Some suggestion?
    Thanks

    You should contact the developers of Flash Slideshow maker as
    soon as possible. They'll need to address this inside their
    product.

  • Flash Player ignores my sound settings

    With my Creative Xi-Fi Sound card software I have accurately configured how stereo sound has to be upmixed. This especially includes the crossover frequency and volume of my subwoofer. Unfortunately the Adobe Flash Player is the only software (I am currently using), which does completely ignore this and does its own 5.1 upmixing. Unfortunately this gives me way to much bass and makes youtube less entertaining (especially when watching music clips).
    Why isn't there any option to disable this 5.1 upmix and let the user decide (system wide) how stereo sound has to be treated?
    Best regards

    I had the same problem with my X-Fi and its software upmix (useless in the case of flash player). Apparently, Adobe thinks that upmixing flash sound to match the system speaker configuration is the right way to go (ignoring the horrible results in the audio quality, like in the bass balancement and in the center speaker being too loud), and they are not going to change this behaviour soon.
    However, i found a workaround in this old post ( http://forums.adobe.com/message/5352195 ): you need to add the line
    UseWAVPlayer=1
    to MMS.CFG , located in C:\Windows\SysWOW64\Macromed\Flash in 64bit windows.

  • Flash player overriding system sounds?

    i've been having an issue with sound recently, involving the latest version of flash player. whenever it plays audio, any and all system sounds will not play. is it a sound card conflict of some sort? i doubt it, because it was working fine prior to this, but it has me dumbfounded more than anything else. my flash player version is 16.0.0.235, i'm running windows 7 64-bit, and my browser is firefox version 34. if you need any more information i'll provide it. can somebody please help me solve this?

    I too have been having problems with this. I've yet to find the exact cause, but when certain Flash based web application require it, it will sometimes cut out.
    For example, I always run into this when I'm playing online chess. It'll be fine for a bit, but after a couple of moves in, the sound will cut out, and not just for chess, not just for the browser, but for everything on my computer. If someone is currently playing sound, like a Skype call or a video, it'll keep playing oddly enough. However if I pause, skip, or do anything to reset said player, the sound will then go out on it.
    On another site that I'm looking for answers for this problem, other users have experienced this issue when they're on Tumblr. They say that after starting a video or two on the site, the sound will go off. So I don't know if this problem is just started by certain type of flash applications, or if maybe it's ones that take higher memory.
    There are two ways I might have to fix it. One way is if I go into my sound settings, and I alter something, and then am able to hit "apply" it'll sometimes kick it back to normal. If though I let the problem persist (such as playing chess for a long while without going to fix it) it'll not be fixable by this method because something goes wrong with the CODEC, and I'll have to do a full computer reset to get the sound going again. Putting things like headphones in does not fix the problem either.
    I'm on an HP laptop, using Windows 7 64bit. I use Firefox as my browser of choice. Sound is run by an "IDT High Definition Audio CODEC." Flash is updated, and I've tried a full uninstall and reinstall to fix the problem. I've checked my sound card's drivers to see if those needed updating, but setting them to an older version or having them fully updated both don't help fix the issue.
    So yeah, multiple people are having this problem, and a solution would be wonderful.

  • Flash player block the sound. [SOLVED]

    Hi !
    I'm having a problem with Flash which is the kind of little annoyance that can quite quickly get on someone nerve. Here it is:
    Every time a flash video is played, the flashplugin stop the sound from working anywhere else. What actually happens is that if I type "lsof /dev/dsp/" the output will be the process in which the flash video is, or has been played. The major problem is that even if I leave the page containing the flash video, as long as the process is active I won't be able to have any sound... So I have to kill the process.
    This has been more tolerable lately since I switched to Chrome, since every tab is its own process I just have to close the bad tab, but that is still quite annoying.
    I have absolutely no idea what can cause the flash plugin to act like that, I've searched over google and this forum and haven't been able to find anyone having the same problem... Am I the only one to experience that ?
    On a seemingly unrelated subject, the sound in flash video is delayed by about one second, whereas it is good in any over case (amarok and VLC).
    I am running arch 64, and am using the flashplugin that can be found in the extra repository of Arch:
    pacman -Qs flash
    local/flashplugin 10.0.42.34-1
        Adobe Flash Player
    local/libflashsupport 9.0.21.78-5
        Macromedia flash plugin support lib (OSS SSL)
    Any help would be greatly appreciated.
    If something isn't clear, please ask me, I am French so my English might not be perfect...

    Using your message I went to the Arch wiki and found that. I've done wht they said by adding snd-pcm-oss to my banned modules, and everything seems to be fine !
    The sound delay also seem to have disappeared, or at least reduced a huge lot.
    Thank you very much for your help !
    Cheers to the both of you, i was having the same problems and they were driving me nuts!

  • Flash Player - Newest version - sound

    Hey,
    I'm wondering if they finally added the option to choose, what sound output I want (Stereo/mono/surround) or if there's some fix for it?
    Otherwise I'm sticking with old version Adobe .
    Thanks for answer.

    Here is the direct link for downloading the stand-allone installer:

    And browse through the page where it says:
    If the ActiveX Control for Flash Player fails to install, download the

  • Flash Player 10 - NO SOUND!!

    I really dont see the point of this. its jsut following the res tof the people that are asking the same questions as me. At some stage a few weeks ago i losat all sound on all my flash movies including ABC Iview. There has been no upgraded, malfunctions or any reconfigurations. I have looked on google and a lot of people have dixed the issue by running the uninstaller and reinstalloing it. I did that and i made no effect. I then upgraded my sound driver and reinstalled it. That made no efect. I changed browsers and that made no effect. The problem is Adobe Flash Player 10.5.45. The latest addition to the flash player bunch of F**kups. Just like Adobe's Phone system that cannot take the options you eneter even though it tells you what to push.
    Can someone kidly help me with this issue. I am at whits end in trying to find the problem. I have tried everything short of reformatting and that is not an option - as the OS is only weeks old!!

    I have been having problems with Flash not working properly
    since installing an HP all-in-one network printer (model c6280).
    Before today, I never saw a flash related error occur with the

    flash, it would ask me to install Flash again. This morning I
    finally got around to trying to fix that and ran Adobe's
    uninstall_flash_player.exe, rebooted, then reinstalled flash. The
    next time I ran HP's support center I got the above message.
