Plexamp Raspberry Pi, Direct Play FLAC?

I’m using the instructions from this link Plexamp for Raspberry Pi Release Notes

I’m using OSX Plexamp 1.1.0 and the full Plex app on iOS to send music. Cant change music quality in desktop Plexamp (as far as I’m aware) and iOS Plex app Remote Streaming music quality set to Original.

My Plex server is ‘hosted in the cloud’ whether this makes a difference?
Also the Pi is running a Retropie image.

I did see this snippet in the log when sending a flac track to Pi Plexamp:

DEBUG - MDE: xxx: Direct Play is disabled
DEBUG - MDE: xxx: no direct play music profile exists for http/flac/flac
DEBUG - xxx - audio.bitrate limitation applies: 865 > 192
DEBUG - xxx - audio.bitrate limitation applies: 865 > 192
DEBUG - MDE: xxx: selected media 0 / 389045

I’m amazed I got it working at all, now i’m just one step away from getting it direct playing heh
