SOLVED: Audiobook Progress

[Jamie Chapman]

I have been using audiobookshelf for a while after unsuccessfully trying my audiobooks in Jellyfin a few times. While audiobookshelf is better overall, since it is specifically designed to work with audiobooks, I am hoping to move this feature back over to Jellyfin, to keep everything in one media management system. 

I still have to figure out creating opf files for all of my audiobooks, hopefully in an automated way (any hints or suggestions would be appreciated!), but once this is done, and the issue I am experiencing is worked out, I should be able to accomplish the mission. 

I have been doing quite a bit of reading about Jellyfin's ability to track listening progress with audiobooks (all of my audiobooks are in m4b format, with proper chapters, etc) when setup in a Books library. 

I gave it a try last night, and it's doing the same thing that I have experienced every time I have tried this. I listen for 5 or 10 or 20 minutes, well past the minimum resume time, but when I stop the audiobook, and then go to my home screen, or back to the audiobook directly, it just starts again from the beginning. 

I am running the latest, 10.11.4, using jellyfin/jellyfin:latest (official repository).

I am using the web browser version of jellyfin for the client, since JMP is dated. 

I am guessing that it must be me doing something wrong, but after all of the reading that I have done on this topic, I can't, for the life of me, figure out what it might be. 

Thanks for any help you can provide.
