The fact is that reverting seems to produce valid files anyway.

If I feed the "broken" output file to ffmpeg -i, the audio samplerate is
correctly shown, and there's no other warning about this issue.

Maybe it's just the input file that's broken (it is, since it also has
borked h264 timestamps...), but then ffmpeg is able to produce valid
Matroska files anyway.
