grab an Apple tv box and DL the YouTube app and stream away. can output HDMI and if you find an older 4k unit it also has optical out.
I've used one for years to stream YouTube, tidal and every other streaming service available on apple devices. It outputs Red book CD quality primarily. Not for critical listening, maybe, but very close and way easier to use then almost any other streamer out there, granted you have a TV in the room.
