After more investigations, when I get no audio or choppy audio from the
beginning, it's because I enter this condition in gstaudioringbuffer.c
default_commit() function:

      /* segment too far ahead, writer too slow, we need to drop, hopefully
UNLIKELY */
      if (G_UNLIKELY (diff < 0)) {
        /* we need to drop one segment at a time, pretend we wrote a segment.
*/
        GST_ERROR("skip because diff < 0");
        skip = TRUE;
        break;
      }

This condition is always TRUE when I get no audio, and most often TRUE when I
get choppy audio. This condition seems to be reached in sync=true and is never
recovered correctly.

Not sure it helps with the initial issue in this bug through...
