This unfortunately inserts silence shortly after resuming, right after
the samples that were held in the buffer during pause. This can possibly
be avoided with prebuffering (not tested).
(cherry picked from commit 819065990b37da8491d82c3538eca6b8a4d516f3)

This commit is only backported to ease further backports. Audio output
plugins have no notion of "resuming from pause" in VLC 1.1.
