    *         or a reference to a new AudioTimestamp instance which is now owned by caller

    *         if timestamp parameter is null and a timestamp is available,

    *         the AudioTimestamp instance is filled in with a position in frame units, together

    *         with the estimated time when that frame was presented or is committed to

    *         be presented.

    *         In the case that no timestamp is available, any supplied instance is left unaltered.
