Using 12.04, 64bit. Does not happen in Firefox though.

After some time, the flash videos in the Chrome browser start to speed up. Resulting in crackled sound and generally making the videos unwatchable. Further, I can hear some random crackles - even with no sound playing application open. Cant clear say what causes this. I had times where I could watch several videos for 2 hours straight, next day the problems began after less than 20 minutes.

Needs reboot to resolve my problem.

Other audio applications like Banshee or HTML5 videos are not effected, event not in Chrome.

I think I have a similar problem. I found out that instad of restarting the whole OS, it is enough to restart pulseaudio only (killall pulseaudio). Moreover, firefox (in my case) is not affected by this bug and it plays flash videos & html5 videos without any glitch. – Matteo Jul 6 '12 at 7:32
It seems that a lot of people are affected: ubuntu forums -- ubuntu bugs – Matteo Jul 6 '12 at 7:34
This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions on filing a bug report are here. – Jorge Castro Jul 12 '12 at 15:19
I have the same issue, and only in Ubuntu. I don't have this issue using Chrome on in Windows 7 on the same machine, strangely. In any case, while a fix is made, Matteo's idea worked for me. – Don Jul 13 '12 at 13:56

Something from Ubuntu Bugs that works for me: "switch to an alternate output device (and then back again) in Settings > Sound." – dxvxd Aug 28 '12 at 2:50
