There is no suitable candidate to pick from the list for value "Check if it's AirPlay 2"

Building key noise-reduction refinements into THX® Certified Select high-current amplification, the Onkyo TX-NR6100 sets the bar for reference sound while bringing 8K/60p and HDR10+ video to your compatible display over HDMI®. Enjoy Dolby Atmos® and DTS:X® soundtracks through your height-enabled surround system or use upmixing and virtualization solutions from DTS® and Dolby® to create a 3D sound-field from any layout. Cue and control music around your home with voice assistants Hey Google or Alexa, and connect a second display via HDMI Sub/Zone 2 output. Chromecast built-in, AirPlay 2, DTS Play-Fi®, and Works with Sonos cover every multi-room situation, and if you connect passive loudspeakers, you can switch between a 7.2/5.2.2-ch and 5.2-ch + Zone 2 layout at the touch of a button thanks to dedicated Zone 2 speaker terminals. Features such as a quality MM phono equalizer and bi-directional Bluetooth® wireless technology make this value proposition even more persuasive.
