------- Comment #2 from Stefan Kost (gstreamer, gtkdoc dev)  2008-08-07 11:32 UTC -------
GST_DEBUG="*:2,*audio*:4" gst-launch-0.10 2>&1 audiotestsrc num-buffers=40 !
alsasink | grep -o "running: .*$"

end/bin have discontinuities, but that probably rounding for output


GST_DEBUG="*:2,*audio*:4" gst-launch-0.10 2>&1 audiotestsrc num-buffers=40 !
alsasink | grep -o "rendering .*$"

GST_DEBUG="*:2,*audio*:4" gst-launch-0.10 2>&1 audiotestsrc num-buffers=30 !
alsasink buffer-time=100000 | grep -o " time .*$"

looks really continous


GST_DEBUG="*:2,*audio*:4" gst-launch-0.10 2>&1 audiotestsrc num-buffers=30 !
alsasink buffer-time=100000 | grep -o " align .*$"
 align with prev sample, ABS (1) < 22050
