When SourceBufferPrivate::reenqueueMediaForTime we search for the TrackBuffer's sample that contains currentTime and beyond. Audio samples are packed in 2s buffer. So say we need to re-enqueue samples at currentTime=1.9s ; we will re-enqueue a MediaSample that span from 0 to 2s. When this is given to the audio renderer, the synchroniser's time will jump backward to 0.
