I would use Audiobookshelf as a source for Music Assistant, and then play them via Music Assistant. That way I can use my Sonos speakers (and eventually Snapcast speakers), synchronize across rooms etc. If I had to use Audiobookshelf directly, I would either play it from my TV with the TV on (only other way I can use my Sonos Beam) or on my phone with a Bluetooth speaker or headphones.
