I'm having this iproblem too now, but just since a few days ago. The only thing that could have changed is I did some package updates. Here are the latest ones:

500ms silence, they video is a little jumpy too but much less than the audio). Killing pulseaudio (which gets restarted automatically) fixed the issue (for now). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1021052 Title: flash plugin (or browser?) audio problems in precise Status in “pulseaudio” package in Ubuntu: Confirmed Bug description: Since a while (I can't tell it's since upgrading to precise or later, sorry) flash has serious problems. I am not sure it's pulseaudio related, so it is possible I report this bug against wrong package. The problem: On two different machines (a desktop PC and a notebook) with testing both of firefox and google chrome (on both of the machine) I have problems with the flash, including youtube videos, various flash based games or anything which plays sound (it seems). The audio is either very distorted and the video is played very quickly (on youtube) or the the speed is ok "only" the audio is simply can't even recognized. This is also true for google talk plugin btw, I am not sure it is related! This was with google chrome on both of the machines. With firefox, video speed is OK, but is "jumpy", a fraction of second audio then silence, etc, while according to top, machine has free idle CPU time. The video is also jumpy. Please not that other applications seems not to be affected, like playing videos with mplayer, audio and video are OK on both of the machines, it seems it's seems it is only browser and/or flash related problem "only".
