Comment:

 1. Our native Opus decoder produces garbage with user2.mka; workaround is
 to use libopus for decoding (use "-c:a libopus -i user2.mka").
 2. MKVToolNix does not produce a real mp3; it produces a Matroska file
 with Opus audio in it. Using an mp3 extension does not make a proper mp3
 out of it.
