I recently updated my Ubuntu from 11.10 to 12.04 lts and there seems to be a problem while I'm playing YouTube videos they, for no reason, start to fastforward (audio and video). This does not happen with other programs or websites only in YouTube videos. It does not matter if they are in flash or in HTML 5 player this problem persists throughout

Which browser you are using, if its Firefox then try disabling addons and play them. – tijybba Jul 3 '12 at 5:09

Some video playback tries to synchronise things to the sound card's clock. Is there anything out of the ordinary about your audio set up, by any chance? – James Henstridge Jul 3 '12 at 7:12

For a very brief time, Youtube recently exposed an experimental player on their site with fast and slow play capabilities, and this may be affecting the current player. If this is the case, it would help to clear your browser cookies.

Thank you, the problems seems to have been that. :) – Ovatsug Jul 4 '12 at 20:54

In my case I solved it this way; First install "PulseAudio Volume Control" if it is not installed yet;

sudo apt-get install pavucontrol

Now start "PulseAudio Volume Control" and go to the Configuration tab. Under "High definition Audio Controller" I had "Digital stereo (HDMI) Output" selected. I had to change that to "Off". I also had to change the build in audio profile from digital to analogue, otherwise I didn't hear anything.

edit: after the change above, it still happens sometimes. But I can use pulseaudio -k to restart pulseaudio. (-k will kill it, but it will restart automatically).

If pulseaudio -k works temporarily, try this guide to replace pulseaudio with the alsa audio component. It's worked fine for me ever since. (Ubuntu 12.04)

The pavucontrol did nothing for me, but pulseaudio -k (sugested by Wimmel) and refreshing the site helped me.

PS. sorry for leaving a new answer, but I was not able to comment on Wimmel's, I guess I do not have the needed reputation (6 ATM).
