Airplay and multichannel, via AppleTV

I would like to know if Roon support multichannel over Airplay, and how to do it, via AppleTV. My HBO app support multichannel via Airplay, so it is possible. :slight_smile:

Is Airplay always stereo?

From wikipedia: " The streams are transcoded using the Apple Lossless codec with 44100 Hz and 2 channels symmetrically encrypted with AES, requiring the receiver to have access to the appropriate key to decrypt the streams.[12] "

I’ve never heard of any airplay receiver that played anything but stereo.
