Despite its many flaws, I use Plex as the single place for all my video and audio content. If you pay for the lifetime pass, you get access to an app called Plexamp which is designed for playing back audio.

Cancel your subscription, download all your books from audible, put them on a NAS, run Plex, and use Plexamp for access.

I still buy things via Audible, I just immediately download them and load them into my Plex server.
