According to my information, via Airplay version 1 any audio format is converted to ALAC 16 / 44.1 by the sending device before being sent to the receiving device.
Also based on my information, the Apple TV 4K has a fixed audio output at 16/48.
Apple Music sends in ALAC format up to 24/48 if lossless audio quality is selected on Apple TV 4K.
To listen to Apple Music on my Apple TV 4K I don't use the HDMI audio output but I use Airplay version 1 + Airport Express version 1.
I also use Apple Music + Phone X + Airplay 1 + Airport Express 1 (bitperfect at 16 / 44.1 according to the tests done here - https://audiophilestyle.com/ca/bits...ss-mess-part-2-airplay-r1026/page/5/#comments) but I prefer to use Apple TV to not drain the battery of the iPhone.
[[I use iPhone to control Apple TV remotely with the Music app (it is a pity that through the iPhone Music app it is not possible to select Airplay 1 devices available for Apple TV .. it is not even possible to select an Airplay 1 device as default audio output but only HomePod = Airplay 2 .. every time you need to turn on the TV and use the Apple TV control center to select an Airplay device 1)]]
My question is:
What happens when I receive a lossless 16.44.1 format from Apple Music on my Apple TV 4K which I then send via Airplay 1 to my Airport Express 1?
Airport Express 1 receives from Apple TV 4K lossless bitperfect ALAC 16 / 44.1?
Apple Music on tvOS, is it bitperfect like iOS at 16 / 44.1 using Airplay 1?
I forgot to say one thing. Airport Express 1 is connected to my Naim UnitiQute 1 via digital input and the Naim app confirms to receive 44.1.
