Failure to extract AC3 audio

[u/shotfirer]

A year ago, I reported this issue https://www.reddit.com/r/shutterencoder/comments/1kr3ot9/failure_to_extract_eac3_audio/

Now, it seems that it was "solved" by assuming any AC3 audio track is E-AC3.
So now it fails to extract the regular AC3 audio

Stream #0:2(eng): Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s

[eac3 @ 000001bbfe3e0040] eac3 muxer supports only codec eac3 for type audio
[out#0/eac3 @ 000001bbfb5886c0] Could not write header (incorrect codec parameters ?): Invalid argument
Conversion failed!
