Firestick, EAC3 5.1 Audio only playing as PCM Stereo

[ke8ort]

It's possible Plex is transcoding EAC3 into AC3. I did try a few more files and it seems that if it is an AC3 audio track, it will play it properly, however AAC 5.1, EAC3 5.1, and DTS codecs will play as stereo. Unfortunately, I have very few AC3 files. Beginner question: Can I set Jellyfin to transcode EAC3 into AC3?

I have looked in the Jellyfin settings but can't find it, where should it be located?
