    Use either or Popcorn Audio Convertor https://www.videohelp.com/software/PopCorn-MKV-AudioConverter or MKV2AC3 https://www.videohelp.com/software/MKV2AC3 Both do it in situ and don't touch the video only remuxing the audio.

    Popcorn got flagged and deleted by Panda as a virus.

    False positive - used for years and the author is often on the Popcorn Forum . Re 4K file, it probably hasn't been updated to handle these. http://www.networkedmediatank.com/showthread.php?tid=20887&highlight=audio+converter

    Due to the many anti-virus programs not working properly and reporting the compressed .EXE file as various viruses or trojans, I have decided to release an uncompressed version of the program as well. This, however, doesn't support auto-updating (it would attempt to download the compressed .EXE version), so try the compressed .EXE first and use that one if your anti-virus software is properly coded.
