Which is a different issue from the programs that do not recognize the file
at all. "Fixing" one will do nothing at all to solve the other.

There's nothing wrong there, it says "Extensible wave format" for the file
which is correct. It does not print the "SubFormat", which indicates AC3.

Yes, there seems to be incorrect interleaving. It goes away when re-encoding
the audio. I think -acodec copy and AC3 do not work together correctly.
Isn't there even an issue open about that already?
