I have ubuntu 12.04, 32-bit.
I've been having this problem for a couple of days now.. Youtube videos are playing in fast forward on google chrome and in slow motion on firefox! I have read some of the suggestions about it.
So far I've installed Volume Control and I've changed the Output audio device from HDMI to built-in speakers like someone suggested but I'm still having the same problem.
I also saw another suggestion about the different plugins for flash and them clashing but I have no clue how to fix that.
Please help? Bearing in mind that I'm a beginner and don't know much about programming at all!
Ubuntu – Youtube Videos are Playing in Fast & Slow motion in Chrome & Firefox respectively

Take a look at this YouTube HTML5 Video Player. It might be flash related since Adobe decided not to keep updated for flash under Linux. Choose to use the HTML5 player instead of the Flash player for most videos.
Also you can try, disabling hardware acceleration in Flash by right clicking the video, and choose Settings. Or you can reinstall your flash plugin.
