  You might be able to do this without resorting to a new event, but
instead by having the jitterbuffer send new new-segments which is the
technique we also use for sparse streams (i.e. the decoder sees a
new-segment, knows that no data is available until a certain point and
therefore pushes out comfort noise up to the new start position).
