Description of the bug

It appears eac3 is not recognized as external audio.
Checking manually with MediaInfo, it recognizes it as eac3 as expected.
The general feature of external audio tracks work. For example, if I change the extension from 'eac3' to 'ac3' then JellyFin server suddenly recognize it well. So I guess it's a parser issue. It's a temporary fix but it create another issues when I already have ac3.

Reproduction steps

Format library according to documentation, and throw a movie.mkv within.
Jellyfin server recognize it.
Throw: 'movie.eac3' or 'movie-en.eac3' or 'movie-eng.eac3' in a movie folder near 'movie.mkv'.
Jellyfin server recognize none.

Temporary fix:
5. Change 'movie.eac3' to 'movie.ac3' (or any other file above).
6. Jellyfin server recognize all as eac3.

What is the current bug behavior?

Not recognizing external eac3 files.

What is the expected correct behavior?

Recognizing external eac3 files as selectable audio in movie page.

Jellyfin Server version

10.10.0+
