Does Airplay 2 support Hi-Res Lossless streaming?

The answers above seem to be bots. No, Airplay 2 does not support HiRes lossless. It is limited to 16/44.1 but this should not be a problem as HiRes is mostly 'snake oil'. You are unlikely to be able to hear any difference. Airplay 2 is actually downgrading the lossless stream from Apple Music to AAC256. In other words, although Airplay 2 is actually capable of doing proper lossless with other apps (e.g. Qobuz), Apple's own Apple Music will stream AAC256 over Airplay 2. There are numerous posts about this on the net. No idea why Apple has chosen to do this. Apple's AAC256 does sound good but lossless it isn't. If you want HiRes to your HiFi you need an external DAC. Btw, Airplay 1 can and does stream Apple music lossless.

Bluesound engineers do have a workaround for you. "The only way to get Apple Lossless to your Bluesound Player is via AirPlay from a MacBook". See here.
