Same issue here, this effects *all* streaming video and audio, but also from files played locally. I noticed also that when the choppiness occurs the whole UI is affected meaning the responsiveness drops. If I am typing the typing is delayed by a second, if I am moving windows there is also a delay. I was running the resource monitor and noticed that whenever choppiness occurs ALL CPU cores activity dips for a sec and then goes back up. It's as if the entire system just goes into "wait" state or something. I have a core i7 980X with 6GB of ram so this is definitely NOT a resource issue. I have an ATI radeon 5870
This also started happening recently, about 2 weeks ago after an update. Also noticing that the delay in typing and responsiveness is present even when there is no video or audio playing. I've tried above solutions but no change: - Turning off PulseAudio timer scheduling - Setting also mixer automute to disabled I've also tried loading previous kernel versions (about 3 versions back) but no change. Please fix!
