 Summary of the bug:

 Opus Audio in MKV/WEBM/MKA containers is has crackling and lots of
 clicks/artifacts when played in ffplay, mplayer or using shared libraries
 (e.g. Kodi)

 How to reproduce:
 {{{
 Mux Opus Audio into MKV.  Play it with ffplay, mplayer
 or anything leveraging ffmpeg shared libraries.
 }}}

 MPC-HC has zero problems playing these files at all.  I've taken the first
 minute of a bad MKA (for sizes' sake) and have attached it.  If you
 extract the Opus, ffplay will play it fine.
