audio: avoid wasting CPU due to continuous wakeup 

Thsi code path happens during seeking. If video is still being decoded
to get to the first video frame, audio has nothing to do, as it is
synchronized against the first video frame. We only want to wake up if
there's an actual state change.

Fixes #1958.
