Comment (by agni451):

 the -async 48000 flag is missing.  I need it because there are often gaps
 in the audio, and that corrects them.  This particular sample doesn't have
 gaps like that, but it does have the audio channel layout change, and that
 causes massive confusion when it's determining how many extra audio
 samples to add (it adds too many).

 Please use the full commandline listed above in comment 12, then play the
 file without seeking at all.  You should see the "pause" phenomenon that I
 mention, and if you really want to see the desync, demux the output ts
 file and then remux the audio and video into an mkv and try playing that.
 It won't just "pause" it will be completely out of sync.
