Sound stops on flash player, have to restart firefox to have sound again (until next time)

Asked by Vediovis on 2010-01-31

good afternoon everybody. I have problems with Karmic 9.10 , my flash player
with firefox 3.5 stops sounds and i have to restart the browser to have sound
again with youtube (until new sound crash). It is quite recent and everything was
working fine before. Does it ring a bell to anybody?

Reproducible: Always

Steps to Reproduce: a flash video on youtube, dailymotion, etc...
2. wait for the sound to stop (won't be long)
3. kill firefox process, start it again and return to step 1

my extensions: ColorZilla , DownloadHelper , Download Status bar, Firebug,
Flagfox , Flashblock , gTranslate , Tools, ImTranslator, LoremTools,
Web developper, Zend Studio

Flash player: Shockwave flash 10.0 r42

I made a bug report to the firefox team, and they replied me it was coming from the Ubuntu build.

Errr.... Help?

Try adding the mozilla ppa and installing a later build.

Are you using 64bit Ubuntu?

I would prefer to keep everything current. In case there's a mistake somewhere and my configuration would be not current anymore, the perfect solution would be to correct it to be totally current again.

I want to follow the synaptic updates and to not fork from the distrib. So I think there's something to adjust somewhere in my machine to be back on line.

Notice: I am not the only one to notice this very recent problem (since around 2 weeks) (cf firefox report)

uname -a: Linux my-desktop 2.6.31-18-generic #55-Ubuntu SMP Fri Jan 8 14:55:26 UTC 2010 i686 GNU/Linux

Thanks :)

It is part of the distribution, the PPA is the official PPA for Ubuntu.

You may need some sound tweaking but sound troubleshooting is not my forte as I have never had a sound issue personally.I recommend the repo but if you want to stay on the official repos that is fine.

Can you give the output of:

dpkg -l | grep flash; dpkg -l | grep gnash; dpkg -l | grep swf

I also experience this problem, although it seems to less regular than Vediovis experiences. Maybe happening once every few hours.

Like Vediovis I am running an up to date system, I just leave the Ubuntu update manage update what it wants, when it wants to.

Only firefox extensions are web developer and stumble apon.

sudo apt-get --purge remove libswfdec-0.8-0 adobe-flashplugin; sudo apt-get --purge autoremove; sudo apt-get update; sudo apt-get install flashplugin-nonfree

Looks like you have erroneously downloaded the deb from and installed it. You should use the repos as this is the correct method to use.

ok, I done that this morning. Restarted the whole thing, and so on.

Problem is stil here.

There's a few improvement anyway: I noticed sometimes refreshing the tab "can" be enough to allow sound to work enough. The sound crash seems also to be limited to the tab and not to every browser instances.

I will come back later to confirm or infirm these precisions, but for sure I still can't watch my videos totally as the sound stops very often.

Thank you very much for your help, please tell me if you have any other idea.

Good evening!

any messages in the log files?
I did experienced similar problems with Flash and RealPlayer, they both were directly opening ALSA device. So only one could play at a time.

You could always download the tar.gz suitable for your ubuntu architecture and put the .so in your browsers plugins folder.

Can you help with this problem?
