New Apple TV 4K - No High resolution Lossless

[priitv8]

I’m not sure it’s a glitch, I’m on beta but you’ve always been able to Airplay audio to your  TV, and since Hi Res lossless plays on the iPhone the UI is just showing you that that is what the phone is getting, but also that the highest you can get out of the  TV is 24/48 when you go to the audio quality settings.

I am on official 14.6 and whenever I AirPlay this Hi-Res track to my aTV 4K, all indicators turn back to Lossless and 24/48. So I still have not managed to re-create this display.
Indeed, I did not check what actually arrives at the AVR.

Just as with older movies shot on film which can be scanned at 4K (or sometimes much higher), there is a universe of albums recorded in analogue onto magnetic tape which can be digitised at 24/192 or even higher (or DSD). A good example is Hotel California, which has been 24/192 2CH and 24/96 MCH from the old DVD-A twenty years ago when the master multi-track analogue tapes were baked and captured at high resolution before they fell apart.

Right. It is nice to capture as much of that original sound of magnetic tape as possible (though science does say 96/24 would be far more than enough bit depth & resolution for analog tape). However, most music produced in the last 20 years will have likely been tracked digitally to Pro Tools.

Yeah it comes up for me whenever I Airplay from my iPhone to my  TV, my receiver always displays 48k though regardless, my receiver is definitely capable on 192kHz though because I can get that in Amazon Music from my Fire TV cube. I just think the  TV resamples everything to 48k

...my receiver is definitely capable on 192kHz...

Apparently it is of very limited use anyway: https://forums.macrumors.com/thread...hd.2299873/page-2?post=30011536#post-30011536

PS I also have measured, that only in Pure Direct mode is my AVR capable to play back frequencies up to 100kHz. As soon as I switch on ANY processing (be it simple EQ or Bass Management), the bandwidth drops to 24kHz - a sure sign of 48kHz-samplerate processing

I don’t disagree with that, I’m happy with how the spatial and new “lossless” tracks sound, honestly 16bit/44.1kHz would be plenty for me, I’d take the  TV outputting at 44.1 and not resampling up to 48 vs getting 192 which I agree is mostly unusable in most systems and probably not perceptible to most ears anyway.

high res audio is very perceptible. I don't understand why appletv 4k doesn't have it. we're connecting amazing sound systems to tv and then we end up not getting proper output.

I doubt we will have hi-res audio on Apple TV ever. The sample rate is fixed at 48kHz since Apple TV Gen. 2. What's more annoying is they re-sample everything, even 44.1kHz, to 48kHz. It's arguably worse than ordinary non-hi-res music.
