    I have the Yamaha RX-475 receiver which is 4K ready but I don't believe it's HDR ready.

    I'm wanting to buy the new Apple TV 4K. Would I have to upgrade the receiver so it will work with my Apple TV for the HDR or could I just plug my receiver via optical cable into my Samsung K8000 TV and have the Apple TV connected via HDMI directly in the tv instead of the receiver so I could still use the surround sound?

    Any help would be great.

    It depends upon what types of audio you want to access? The current Apple TV and Apple themselves do not support the HD formats commonly associated with Blu-ray and UHD discs anyway. As long as Apple aren't extending their audio coverge to encapsulate these HD formats then you can simply pass the audio ordinarilly associated with the Apple TV and content accessed by it through your TV. You can either use ARC or an optical audio connection from the TV to your receiver which should allow you to access multichannel Dolby Digital and DTS audio as well as 2 channel PCM.

    With the new Apple TV 4K all the movies I have purchased through iTunes which are HD will be upgraded to 4K/HDR if available. The only thing is the new Apple TV coming out does not have the optical port but I guess that does not matter if the Apple TV is in the TV and the receiver is connected to the TV via optical cable? I don't believe Apple is changing any audio from what I've read.

    Thank you for your reply, I finally got round to having a play with my old Apple TV with an optical cable and have got it work (The audio formats which you supplied is the same as the old Apple TV).

    With any of the audio options Apple supplies with Apple TV will I loose any sound quality using an optical cable over HDMI?

    No. The Apple TV doesn't have the audio capabilities to handle formats that couldn't otherwise be conveyed via S/PDIF optical.

    My receiver Yamaha RX-475 supports 4K but does not support HDR so I wanted best of both worlds if that makes sense? The only way I thought I could achieve this was by directly plugging the Apple TV into the T.V or have I got 4K and HDR confused? When I watched the Apple presentation it looked like the two could be combined.

    Yeah. I realised my mistake after I'd posted that and edited it shortly after posting it :)


    Yes. you can pass the audio through the TV and out to the AV receiver via either S/PDIF optical or via HDMI ARC.
