 Summary of the bug:
 I converted 2 mka into mp3, user1.mp3 is ok, but in user2.mp3 the talk is
 missing. They alternately count '1 2 3', '4 5 6', ...
 The internet connection is bad for User2
 How could I use ffmpeg to get a mp3 with talk.
 Using MKVToolNix I get a mp3 with talk, so there should be a way
 How to reproduce:
 {{{
 % ffmpeg -i "user1.mka" -vn -ab 48k -ar 16000 -ac 2 -c:a libmp3lame
 "user1.mp3"
 % ffmpeg -i "user2.mka" -vn -ab 48k -ar 16000 -ac 2 -c:a libmp3lame
 "user2.mp3
