On the road to a possible solution here if your home is all on S2 - I think this can be configured with a custom profile.
The default profiles are stored at your install path Plex\Plex Media Server\Resources\Profiles. The default Sonos profile already seems to have upper limits set for 16/48. According to this guide, if you create a profile at Users\[username]\AppData\Local\Plex Media Server\Profiles it will override the default.
I copied the Sonos profile to the user profiles folder. I then upped the bit depth limit to 24, commented out the upper limit for bitrate, and changed the transcode target from aac to flac. Restarted Plex, but it’s still transcoding 24/48 files that should be direct played.
Does anyone know how to configure the Sonos profile xml so that it functions as in the S2 example in my most recent reply to this post?
EDIT
On further research, it would seem that custom profiles are only “officially” supported for DLNA devices. Does this mean there’s no way for users to override the default profile for Sonos?
