There is nothing wrong with that. Audio sounds like a dane. :) I mean this is how it is supposed to be.
I know. I reported a problem, because the answer was "Bye bye", but I didn't know it also meant "Hello". I was confused, it sounds so much like "Hi", and also means Hi in Swedish.
Danes use "hej" when they say hello AND when they say good bye. Often they will say "hej hej" when they say good bye.
This sounded to me like "ha" or Danish "har". The sound must have been cut off at the end.
