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 -

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

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

I've added tsched=0 to the line (/etc/pulse/default.pa):
load-module module-udev-detect tsched=0
