Any news on if it supports higher than 16/48?

 

I couldn't find anything yet.

 

I was trying to see if their new HomePod supports 24 bit (that would mean AirPlay 2 does) but their tech specs doesn't mention anything: https://www.apple.com/homepod/

 

Current AirPlay streams audio using ALAC at a fixed 16/44.1kHz resolution. Possibly the confusion comes from the Apple TV v2 and later that resamples the incoming AirPlay audio stream to 16/48kHz.

Good old Airplay allows multiple endpoints - I don't understand what you mean.

Indeed, though being able to select more than one AirPlay receiver depends on the sender, eg, iOS doesn't currently support it.

Actually I think you'll find that over ethernet, AirPlay (1) supports 24bit at higher sample rates.  It's only limited to 16/44.1 over WiFi.  Hopefully that will change with AirPlay 2 as too many devices are now 24bit and HiRes music sales are on the rise.

 

In all my testing and everything I ever seen, AirPlay doesn't support high resolution.  

 

Indeed. I haven't encountered any AirPlay devices (both official and unofficial) that anounce via Bonjour discovery, support for any resolution other 16/44.1kHz for the AirPlay audio service, regardless of the devices being connected to the network via ethernet cable or WiFi.
