Thank you for answering.  
I have created a new instance of the library (moved /var/lib/plexmediaserver/Library to backup) and added the problematic files. They play fine using direct for both audio and video.  
[working.zip](https://forums.plex.tv/uploads/short-url/mcPXg9pTXrwRPtUwLzlhGbt31Mz.zip) (2.6 KB)  
Second xml is from my existing library (where they recode) and it seems the same except for id’s.

Another thing that I have noticed. After files start recoding, I cannot re-add them to new library on the same server. Same file in any library will fail to play normally until I delete entire Library folder on the server.  
So this doesn’t look like a metadata problem. This is something different.

PS. [Plex Dance](https://forums.plex.tv/t/the-plex-dance/197064) doesn’t work. Only Library delete helps
