the first one always seems to appear first, then it will repeat this untill you
hit stop.

Simple fix

gst-plugins-base-0.10.21/gst-libs/gst/audio/gstbaseaudiosink.c

line 1325

  if ((slaved = clock != sink->provided_clock)) {

changed to 

slaved = (clock != sink->provided_clock);
slaved = FALSE;//BUGFIX
  if (slaved) {

..has been working without any noise artifacts and without dropping out for 20+
mins now. It used to last 5 mins tops, with popping artifacts.

On FreeNode someone with latest version, 0.10.22, says he has the same skewing
problems and audio dropping out
