With the recent mess relating to Apple Music Lossless over Airplay 2, it seemed prudent to ask about Plexamp.
When Plexamp is playing through AirPlay 2 (selected the cast option in-app, then the AirPlay 2 device), is it going over losslessly at 16/44.1 or is it limited by the OS and downsampling to 256Kbps AAC? Theoretically it seems that iOS should support the 24/48 output standard over AirPlay but is Plexamp actually taking advantage of that?
