RE: "Thanks, I just hooked it up via HDMI ARC and can't really see or hear any difference between the optical and HDMI. I thought it seemed strange to take the video signal through the soundbar to the 900f, but it seems to work ok for now. Now I've got to connect my Sony UBP-X700. Saw some 4k last night and it was phenomenal. Used to think 1080p was great back in the day."
When using a 4K HDR/DV capable player, always connect the video to your TV and the audio to your soundbar UNLESS you have a separate Dolby Atmos speaker system (or even 5.1 for that matter) and an AVR that is HDMI 2.0/HDMI 2.2 compliant (4K HDR (DV some models) for both your 4K/HDR/DV (if capable) video and Dolby Atmos audio. If the latter is the case - - you can use one HDMI connection into the AVR for your 4K Bluray Player (and all other components) with one HDMI out from from your AVR (ARC output capable from your AVR) to the ARC capable HDMI Input of the Sony 900F - - which is HDMI 3.
With your 4K Bluray player - with 4K discs or even non 4K discs that have Dolby Atmos - - you will get fully uncompressed (lossless) audio which is the best audio you can obtain. There is NO lossless (uncompressed) audio from satellite, cable, OTA or any streaming site. The best audio you can get from these sources is DD+ which can also provide Dolby Atmos lossy or compressed, if encoded. This is where ARC comes in for the internal apps on the Sony 900F.
Dolby Digital Plus is capable of the following:
*Coded Bitrate: 0.032 to 6.144 Mbit/s
*Audio Channels: 1.0 to 13.1 (i.e. from mono to 13 full range channels and a low frequency effects channel)
*Number of Audio Programs per bitstream: 8
*Sample Rate: 32, 44.1 or 48 kHz
*Bit Depth: up to 24 bits per channel.
