I have a pretty nice 7.1 system in my home office. I mostly use it for gaming and (stereo) music, but with the kids hogging the new TV more and more, I want to be able to watch TV and movies in 5.1 Receiver: Integra DTS 40.2 (circa 2010 This is a 1080P 7.1 receiver) PC: Win 10 / 7700K / ROG Maximus IX Apex / 16GB / Nvidia 1080Ti Audio: Headphones: Asus Xonar U7 Mk2 Speakers: HDMI from 1080Ti to Receiver Video: Alienware AW3418DW (Displayport) - main gaming PC monitor Alienware AW3418DW (HDMI) - on a 4K capable switch: A = Receiver / gaming PC (1080P) B = Work PC (3440x1440) I can run the Netflix app in Windows and it looks great on the Ultrawide. The issue is that I can't get 5.1 audio to work. I think it might be because I'm not playing the video on the HDMI monitor, but I'm not sure. My motherboard has an optical out and my Xonar U7 has a coaxial out - I could use one of them to potentially get 5.1 to my receiver, but I'm not sure if that will work or if I need some certain driver or setting.
