it looks like bug #162024
(http://bugzilla.gnome.org/show_bug.cgi?id=162024)

in gstreamer-properties (or directly in gconf-editor), set your
audiosink to : alsasink period-size=2048

i commited a fix to gst-plugins CVS (would be in 0.8.8).
in the case of the reporter, it did not work because alsa reported to
support any period-count, when it fact it needed a value >= 3 (gst
defaults to 2) -> rotten alsa driver

hope you're not in the same situation
