Audio is showing up in mediainfo and plays in VLC
- Most likely this is a MPEG TS file and does not contain PAT/PTM so brute force is used to detect the tracks. Brute force is not very good at detecting audio
- Use mkvmerge to convert it to a mkv (it's very fast, no quality loss at all)
the resulting mkv can be opened without troubles
source: No audio tracks showing up (but audio plays in VLC)
Pass video through mkvtoolnix
, then loading the newly saved .mkv has avidemux detecting the audio track.
