What I tried doing was PC -> TV via HDMI for video, PC -> Soundbar via optical using the ASUS Xonar SE soundcard SPDIF/Optical. PC -> TV via HDMI -> Soundbar -> only can do stereo sound Samsung MU8000 65 inch 4k 60Hz, HDMI 2.0 with regular ARC Vizio S3651N-H6 5.1 surround soundbar (we'll get to that in a bit) Apparently it's still being sold as new and the packaging shows that it can decode DTS/Dolby so I should get games and windows in 5.1 surround with my equipment. The only PCIe card I could find that wasn't $100+ was the Creative Sound Blaster Z, the red one from like 10 years ago. I'm needing a soundcard that will do the decoding since Dolby Live and DTS Interactive are no longer easy to find, support, and are outdated and replaced by the Atmos software and DTS: X software. So I found out the hard way that not all sound cards do 'decoding' for DTS/Dolby surround on PC which means that only content such as videos/movies that are encoded with DTS/Dolby will work just fine, but video games and Windows 10 itself will only report stereo. I had no idea how much of a headache surround sound is without getting an A/V receiver, let alone, getting surround sound on PC.
