Any plans to support Airplay2?

I use my AppleTV to stream music and movies to the AA in the back yard using a projector setup. The sound quality is decent but the volume is really low. Any idea if Apple Airplay 2 will address this?

Additionally I’d love to be able to add a 2nd AxiomAir for stereo setup. I believe with airplay 2 this would work as it supports multiple speakers playing at the same time.

Any insight?

Thanks.

Kevin.
