I cant seem the get my surround sound working when running my laptop through my xbox one pass through. I have my xbox one hooked to my tv with an HDMI cable and hooked to my receiver directly with an optical cable. When i hook my laptop to the xbox one via the HDMI pass through i get sound from my receiver but its only in stereo. I have changed the xbox tv setting to surround sound and the xbox is configured for optical surround sound support. When using the xbox one alone I get full 5.1 surround and when i use the pass through for my xbox 360 i get full surround sound too. When i open the sound manager on my laptop i can see the xbox one as a sound device but i cant configure it to anything other than stereo sound. Anyone have any idea to get this to work? My laptop doesnt have an SPDIF out otherwise id go direct with an optical cable when gaming in the living room.
 
the trouble may lie in the xbo using optical. if your pc doesnt support a format like dolby digital live you might only get stereo sound.

or it could be that the xbo just isnt handling the passthrough to optical right.

does your receiver have hdmi input? if so this is the route i would go and use passthrough from the receiver if it has it. if not... get a cheap external soundcard which supports DDL and works via usb and has an optical out. i've seen them before floating around on amazon before.

my receiver does have HDMI pass through support. So then id have to go HDMI from laptop to receiver and receiver to tv with HDMI correct? I could give that a try. Im still confused to a few things. One if its an issue with optical why am i getting sound at all? and second if my sound card is being run through realtek drivers why is the xbox one showing it being controlled by an nvidia driver?
 
-optical only supports 2.1 uncompressed audio but it does support 5.1 if compressed. however to do this computers typically need dolby digital live or similar support. you would still get 2.0 sound from this on your sound system.

-there may be two drivers available for your particular onboard... one from nvidia and one from realtek. they can sometimes conflict if you have both installed. this could explain why your xbo says nvidia.

-if your receiver supports hdmi passthrough, surround via hdmi (some really cheap HTIB sets only have 2.0) and has enough hdmi inputs thats the best way to connect all of your sources. i have a standalone receiver (not a dvd/avr combo included in a htib set) and i have all of my sources as inputs to the receiver and one single output to the tv. its incredibly convenient and the best way i can provide audio to my speakers (hdmi > optical for that)

I could try switching to full HDMI i dont have the cabling for that at the moment. i did some further research and nvidia has sound drivers in the GPU for HDMI output so they dint need an additional link from GPU to mobo or sound card. further research has shown that alot of people are having this issue due to EDID handshaking from the tv. Once the sound driver sees the tv can only handle stereo sound the driver locks into that. I'm going to experiment a little bit. what I dont understand is the xbox is set to deliver sound via optical in 5.1 uncompressed. Being that the laptop is hooked to the box it should be able to deliver sound through that optical port and it is but it seems the EDID handshake is interfering.

Your absolutely correct. I currently have it hooked through my receiver and it is working perfect. I did further research and found that optical can only send pcm in 2 channel stereo. being that games send their signal in pcm optical cannot handle the load. Thank you for your help! sorry i drug it out so far. I was incorrect in thinking that optical was superior to HDMI for sound.
