I've got movies playing in fast forward in YouTube HTML 5 mode if I play it in Google Chrome. If I open it with Firefox, it plays well. Any ideas?
If you're using Chrome from the
unstable channels, you probably have a bad Flash plugin enabled (this affects HTML5 audio as well for some obscure reason).
To fix it, go to
chrome://plugins and disable all the flash plugins. Then click +
Details to show the individual versions of Flash, enable them one at a time until the problem goes away.
This is the configuration that worked for me:
If you none of the versions you have work, you may need to install the
sudo apt-get install adobe-flashplugin
Please note: sometimes if the problem still persists then this may be related to pulseaudio, in such case you can use
pulseaudio would start automatically again
And restart the browser and it will work.
If this only works temporarily, you can try replacing pulse audio with the alsa module for good.
I found some solutions:
Reset you're sound settings, (apparantly if you use hdmi for audio and video there is nothing slowing the playback down) so what you have to do is try changing audio playback device :)
One user found that "setting the specific speaker layout fixed my problem (from nothing to 5.1, as that is what I have)."
