I can confirm bug. Running vanilla 10.10 upgraded from 10.04. Removing
gstreamer0.10-pulseaudio package is an effective quick fix.

I still think the problem is of a gstreamer and pulseaudio combination.
I've run two tests using a wav file:
1.- paplay test.wav - pulseaudio rises to 14% cpu in my very old computer. The
sound is ok.
2.- gst-launch filesrc location=test.wav ! wavparse ! audiocoert !
audioresample ! pulsesink -

I've just uninstalled the package gstreamer0.10-pulseaudio and configued
gstreamer to use the pulseaudio alsa emulation. After this, Rhythmbox
started to work.

Sorry, i didn't see your post. Why I have not used playbin? I don't
know. Is that important? Do you want me to run another test using
playbin. Another question: what is playbin?

OK. I've re-installed gstreamer0.10-pulseaudio and I excuted: gst-launch
playbin uri=file:///tmp/test.wav. The pulseuadio CPU rose to 95% and the
rewind stuff came again. It is funny, if you want to use the pulseaudio
alsa emulation you need to unistall gstreamer0.10-pulseaudio, changing

Does disabling glitch-free (using tsched=0) resolve this symptom?

I've added tsched=0 to the line (/etc/pulse/default.pa):
load-module module-udev-detect tsched=0
and executed pulseaudio -k
Is that OK?
Still the same symptom.

Yes I am. I've also installed from the Ubuntu Audio Dev team PPA:
pulseaudio (1:0.9.22~git20100719-0ubuntu1~ppa2) and
linux-alsa-driver-modules-2.6.35 (2.6.35-22.201010171600)

This bug (pulseaudio spikes to 100% causing video delays and even
locking up the entire system termporarily/permanently unless the video
playback is paused) affects me in mplayer and xbmc when using VDPAU
output.

I have a similar problem (high CPU usage by pulseaudio), but under
different circumstances. Whenever I ran or run a VM with VirtualBox, the
CPU can later suddenly spike to consume one entire core. I also have
Pidgin running in the background which plays sounds when people log on
or talk to me.
