What is the expected result?
I would expect that audio with lang cs would have tag role main. But it did not have. Is this --default_language not being used?

Emm... That looks like a bug.

From #370, it seems to be working if you use the 3-character code and it only fails if you are using the two-character code. Is that what you observed?

We'll look into it.

[jakubvojacek]

yes, I have noticed the same. Thank you
