Fix failure to analyse audio in some cases.

This fixes audio-only content when the first-emitted audio is not
at time zero.  This used to cause a seek which is not possible
with audio-only.  This commit removes the unnecessary seek which
was due to missing silent-padding of the first-emitted audio.
