Hi, I mentioned the TV model in my initial post, but here it is again: Sony XBR-43X800D. A 2016 43" TV from Sony which was their first line to get HDR out of the box. I have HDR10, and HLG support.\nAs far as sending audio through the TV, it shouldn't be going through the TV at all. I have the devices I want to use with full audio quality directly connected to the sound bar's input and the sound bar connected to the TV's ARC port via it's HDMI out, so the goal is sound directly to sound bar, video to TV through the sound bar, which has been working without trouble. It was just the weird glitch with the Sony player.\n\nAlso some other information. This TV runs android TV, and can passthrough standard DTS, and Dolby digital 5.1 through ARC, and optical. Also, the TV recognizes the sound bar as a Bravia sync compatible sound system so, the sound bar turns off and on with the TV automatically, and the TV sets the speakers to audio system automatically instead of TV speakers so it's smart enough to know I don't want sound going through the TV. (or, that's what's supposed to happen). I also mentioned in the post that I was able to get the issue to stop by two sets of setting scenarios. Either setting a fixed resolution of 4k either by enabling Auto 2 under the players 4k upscale settings, or setting the output to 4k.\nor the other one is disabling 24p output for BD\/UHD. That's when this happens is on the frame rate change on video with a DTS track, that isn't 4k, or being output at 4k upscale. Hope this helps\n\nI mainly was curious if anyone had ever seen this before because it's so strange, but also easily fixed with the right setting changes.\n\nEDIT: One thing I wanted to add: if the sound was truly going through the TV, DTS-HD-MA would have ben sent as the 5.1 DTS core vs the lossless audio. Also, if I connect a device to a different input from the one the sound bar is connected to, the audio is sent through ARC as it should. Using a device from the input the sound bar is connected to, uses the direct HDMI in of the sound bar. I have a basic 4 port switch connected to the Sound bar's input and the devices I want with direct audio access are on the switch. I simply select the port of the device I want passed through. The Devices include (Roku Ultra 4800, Apple TV 4K 1st Gen, and the Sony UBP-X700). Have disabled control for HDMI on the UBP-X700.
