hi all, 
   when  using gstreamer to play dvb signal, if I set the osssink's sync to true,  the pipelie give 'Unexpected discontinuity in audio timestamps of more than half a second(...) resyncing ' and stalled there....but it is said that 'sync=true ' should work , my gstreamer core is 0.10.14,fluendo-mpegdmuex-0.10.15, and by the way my pipelie is:
    gst-launch-0.10 dvbsrc modulation="QAM 64" trans-mode=8k bandwidth=8 freq=474000000 code-rate-lp=2/3 code-rate-hp=1/2 guard=8 hierarchy=NONE pids=630:512:128 ! flutsdemux es-pids=650:512 name=demuxer demuxer. ! queue ! mad ! audioconvert ! osssink
    and if i add 'sync=false' to ossink , it works but when play with video the audio is heavy lagged. 
    
     I have referrenced to this link https://core.fluendo.com/gstreamer/trac/ticket/46, it seems that these problem should have been resolved.
     anybody know the way out? thank you
