Enforce monotonical PTS

Browse source 
Audio PTS may come from two sources:
 - recorder.getTimestamp() if the call works;
 - an estimation from the previous PTS and the packet size as a
   fallback.

Therefore, the property that PTS are monotonically increasing is no
guaranteed in corner cases, so enforce it.
