Public bug reported:

What I expected to happen:
Playing a flash video eg. from ted.com using chromium-browser. I forward the 
application sound output via the network (using paprefs and pavucontrol). I 
expect glitchfree playback via the remote pulse audio server (which is 
connected with a local threaded network to the local computer).

What happens:
The sound is very choppy and/or the video stops and then fast forwards for a 
couple of seconds. See example here:  http://youtu.be/bv0SoMbJr9g

Step to reproduce:
Enable network forwarding ("Make discoverable PulseAudio network sound devices 
available locally") on the Local machine and "Enable network access to local 
sound devices" on the "remote" machine.
Start a ted.com video and it will stutter. You can get the sound working again 
by switching to local output device and then back to remote. This fixes the 
stuttering until another video is started.

Other notes:
The stuttering only happens for flash content ie. rhythmbox works just fine. 
Html5 version of youtube works (although I am not sure that it always works).
Flash content does not stutter when using local output.
