Sorry, I don't understand what you're trying to describe. Are you saying that that using --audio-file-auto changes subtitle selection?

Are you saying that that using --audio-file-auto changes subtitle selection?

No.

This is a mka file, contains audio and subtitles. --audio-file-auto=fuzzy will load this file, both audio and subtitle tracks apeended. but sub selection will not select subtitle tracks in this mka file.

Highlight one is "disabled", If I remux two file into one mkv, subtitle selection works well.

Oh I see what you mean now. The external files mechanism only assumes the file is one particular type of stream (audio, subtitle, or video). In this case because you passed --audio-file-auto, it assumed it was only an audio file and only selected that track. Checking if the file actually has other kinds of tracks during that step isn't done so it doesn't select the subs. Not sure what the best way of implementing this kind of behavior would be, but marking as a feature request for now.
