I'm thinking of the following setup. I will know for sure when I try but don't want to be disappointed. Hence wanted to tap into the collective wisdom here. Will the following setup work?

Plugin Chromecast into HDMI of the AVR which will be hooked up with speakers. No other inputs are connected on the AVR nor will be a TV. Will I be able to cast audio from Spotify or Tidal to AVR to be played out from speakers? Will this setup work?

Since there is no TV/video-out from AVR, will that be a problem?

Thanks much in advance.
