As stated in the title, the videos which I was watching with normal speed, now I see with x2 the speed or even more.

I was so excited that there was a Flash Player update and now (like always) it doesn't work properly. I tried reinstalling Flash but it didn't work.

I had same issue. Follow these steps for glory:

Completely uninstall flash plugins:

sudo apt-get purge lightspark swfdec-mozilla mozilla-plugin-gnash adobe-flashplugin flashplugin-nonfree flashplugin-installer

rm -f /home/**/.mozilla/plugins/*flash*so

rm -rf /home/**/.wine/dosdevices/c:/windows/system32/Macromed/Flash


Install flash replacement:

sudo apt-get install mozilla-plugin-gnash

Restart your browser and have fun.


killall pulseaudio

Will this work with Chrome? –  Xylo Aug 24 '12 at 14:52

It happened to me with videos: very fast playback and no sound. The problem was that I had selected the wrong audio output (though I didn't change it). So, flash was trying to play audio through my graphics card hdmi output, I chose the other output device and everything worked fine. Make sure this is not your case.

I have sound but it's sped up like video. Now problem solved –  Xylo Aug 24 '12 at 16:14
I have exactly the same problem. Just one more info for newbie like me: you can change the output device using 'pavucontrol' –  Davide Icardi Sep 29 '13 at 14:15
