How To Fix The No Sound Issue in Firefox Flash [Ubuntu Linux Tip]

This is the method that worked for me while using Ubuntu as well as Fedora. It’s not really a method, it’s more of a simple program installation. By no means do I take credit for the solution, but here is the package that will need to be installed:


I wouldn’t even bother saving it, just open with the default application. It will install it and you’ll be sittin’ pretty.

BTW: This also appears to be true for Fedora 8. I had the same problem with the default installation of the new Pulse Audio controller. So, after installing the “libflashsupport” package, the sound in Firefox flash worked again. Refer to my other Fedora 8 guide on this page:

    I spent lot of time trying to find a working solution for this issue (that was really pissing me off btw). But tonight, I found your post in the ubuntu forums and gave it a try. And guess what: sound is now working with flash under firefox / epiphany. Thanks you very much for the tip.

    Hello !

    I noticed a bug in your lib
    First i’ve to say that it solved the problem xD

    But, when i’ve a firefox open and a flash video open (playing or not), all sounds are disabled for system and other audio appz (like banshee)
    when i close the youtube tab in my firefox, everything come back

    thanx again

    Unfortunately, those with AMD64 versions of Ubuntu are screwed by the i386 DEB, and the makefile in that tarball doesn’t work. How can I get this to work on an AMD64?

  • sendderek
    December 18th, 2007 at 11:32 pm

    For me, it was in the repositories.

    The command is (as root):
    yum install libflashsupport

    That’s it!

  • Spyke
    December 19th, 2007 at 1:22 am

    how do I get to the repositories
    maybe I didn’t say it well enough, I have no idea what I am doing in linux
    do i just open up a terminal and type that?

  • sendderek
    December 19th, 2007 at 10:28 am

    Oh! Well, it’s easy to do, so no worries! There are two different ways to go about it:

    With the Graphical User Interface:
    1.) Goto Applications -> Add/Remove Software.
    2.) Type in your password for root.
    3.) Click on the “Search” tab and search for “libflashsupport”
    4.) Make sure “libflashsupport” has a check mark next to it and click “Apply”.
    5.) The package manager will go out, download it, and install it to your computer.

    With the Terminal:
    1.) Open the terminal by going to Applications -> System Tools -> Terminal
    2.) Login as root by typing “su”
    3.) Enter your password.
    4.) Type “yum install libflashsupport”
    5.) The package manager will go out, download it, and install it to your computer.

  • Spyke
    December 19th, 2007 at 10:32 pm

    Well I did that,
    it said the libflashsupport was allready installed.
    but i still have no sound

  • sendderek
    December 20th, 2007 at 12:33 am

    Did you restart the computer?

    If you did, and it’s still not working, I’m not sure what else to recommend other then starting a new thread on the Fedora Forums at http://forums.fedoraforum.org

    Sorry I couldn’t be any more help to you.

    I can’t get this download to work. it says can not be saved try another location. Using Linux Mint (unsure how to get kernel version), firefox 3, Gnome desktop. I’m not sure exactly what Gnome does, but I know I am using that. No flash sound, for myspace or facebook.

  • SendDerek

    If you type “uname -r” in the terminal, you’ll get the linux kernel version.

    Does your sound work in other applications? It might be an issue with your hardware drivers if you don’t get sound anywhere.

    Re. Xico’s comment on May 4, 2009… I’ve been using Linux since the mid-90’s, and although I enjoy Linux and use it every day, I would have to agree with his comment. How could Ubuntu overlook such a elemental aspect of every day Web life – Flash Audio? This is what drives people, who are really trying to make the move to Linux, absolutely crazy. Even Linux Mint which is supposed to include all of the multimedia codecs, etc., doesn’t work with Flash audio. Nor does Mandriva for that matter…

    Personally, I’m committed to Linux, but if we ever expect more migration from Windows to any Linux distro, it MUST be able to work seamlessly, and easily, in all environments as Windows. Otherwise, it will continue to be nothing more than an OS for hobbyists and geeks, and will never become a mainstream OS.

    I followed Joshua’s instructions above, got libflashsupport installed just fine, sound in FF Flash is now working excellent, but every time I watch a flash video, I now have to restart ubuntu in order to get any other type of media file to play (mp3, avi, wmv, etc..). So how do I correct this? It gets kinda annoying when someone points me to a youtube video while I’m listening to music, and after watching the video, I can’t switch back to my MP3 ;-(

    Tricks are not necessary for Flash Player of current version (10.1, I don’t know what about previous versions). I’ve found a problem in the ALSA preinstalled config: wrong device number (0 instead of 1) for the default device. Just apply the following patch to /usr/share/alsa/alsa.conf, or change the default ALSA device using asoundconf (or similar) utility if present:
