Hello this is my first post on here so hopefully someone can offer some advice, I have a pretty simple setup with my PS4 Pro and Sony UBP-X800 to HDMI's 1 and 2 and then my Sony HT-RT5 connected to the ARC HDMI 3 in my Sony Bravia XE9305 TV so I can control everything using my TV remote. I thought everything was fine with PS4 Pro outputting in DTS Surround sound and the UHD Dark Knight Trilogy also doing the same both with the passthrough but when I tried 4K Blade Runner 2049 it was only outputting Dolby Digital Stereo
After looking at the back of the blu-ray boxes I realised that only the blu-rays and 4k blu-rays with DTS 5.1 worked with the HDMI pass through but standard Dolby Digital 5.1 did not, I tried many blu-rays and every one with DTS 5.1 displayed on the box information worked so I know what the issue is. I have tried changing with a few options in HT-RT5, Sony UBP-X800 and Bravia TV but really don't know what I doing so a little guidance would be appreciated.
So why would 5.1 Dolby Surround sound not work with the pass through but DTS 5.1 does? and what HDMI do I need to be fiddling with, I'm guessing HDMI 3 ARC as that passes the audio through? I know I could hook up another HDMI cable from the 4k blu-ray player to the HT-RT5 but I'd prefer not to really as it caused problems I first started setting it up and would prefer to have everything goes throught the ARC
I find it all pretty confusing with the amount of options I can change in all the HDMI's and devices but at least I know what the issue is, I hope so hear back from anyone who knows more about these things than I do, thanks in advance
