You've got 4K with HDR10 and HDR10+ with the 154P, so that definitely needs to go to the TV. However, your AVR will handle audio via HDMI. This includes the lossless HD audio from 1080p Blu-ray as well as from 4K UHD Blu-ray. Right now though - and even if you go Optical out from the TV - it won't do anything with that audio except play basic stereo or basic lossy DVD quality DD5.1. Not only are you missing out on the better quality Dolby audio format, but also the DTS equivalents, too. There's a solution for this. It's an audio extractor. Your 4K BD player gets unplugged from the TV. The HDMI signal goes to the extractor. It splits the signal. Picture goes to the TV via HDMI, sound goes to the AVR via HDMI. Since it's the picture portion of the signal that does 4K and HDR, the TV is getting what it can handle easily. The audio signal doesn't carry 4K HDR. The signal is just sound plus a basic video carrier wave for sensing and sync. Your Pioneer AVR can handle this. The extractor box becomes a junction splitting picture and sound and giving those signals to the bits of gear that can handle them. Here's one of these audio extractors. Amazon link. Once you know the sort of thing to look for , you can do your own searching to see what other models are available. Just a note though. The device you're looking for needs three HDMI connections. This is one in, and two out. Beware getting mixed up with the audio extractors that convert to optical or coaxial. Neither of those connections can handle HD audio which is what you need. You'll also come across basic HDMI splitters. These are cheap. They start at under $10, but all they'll do is give the Pioneer a 4K HDR video + audio signal it can't handle. They're not extracting the HD audio portion of the signal.
