bigpinkdragon286 :
Surround sound in Windows 10 is partially broken. You can fight it all day long, replace drivers to your heart's content, and it will remain partially broken until Microsoft fixes it, again.
Microsoft has been aware of the problem for well over a year. A fix was actually implemented and worked from build 10586.1 - 10586.3. Since then, the problem has resurfaced and remains unfixed.
The problem affects digital coax and digital optical, so basically anybody running digital surround from their Windows 10 system.
The problem affects sound that is encoded in real-time for things such as games, so DDL (Dolby Digital Live) or DTS Live. The effect is not seen on pre-encoded surround tracks such as would be found on a DVD, Blu Ray, or even the Supported Formats test in Windows sound devices properties panel, so performing those tests is not a guarantee that the system is working entirely as intended.
In games that support surround sound through live encoding, speakers are missing, mapped incorrectly, or you get simple stereo.
This isn't a driver issue. All we can do is be patient and wait for Microsoft to fix this, again.
yet another "hardware issue" acknowledged by all the hardware and software manufacturers, yet no one does anything about it lol ... but instead of sitting on improperly configured thousands of dollars of hardware waiting endlessly for an update that will probably never come till we buy a new OS ... nope ... a new computer ... nope ... a new AV receiver ... NOPE. instead we could actually share the solution to this easily solvable problem. (which affects all versions of windows not just 10). the issue is digital uncompressed HDMI PCM 5.1 (or greater channel surround) sound vs the more prevalent down-sampled/compressed formats like dolby through stereo. I just got a new AV receiver with multiple hdmi inputs to plug my devices directly into instead of going through the tv and sending a digital optical line down to the receiver. (don't worry you don't need a new AV receiver lol... probably) I was hoping this would end confusing configuration issues--nope. having the same issues I had as my previous setup.
if i'm not mistaken, my understanding is that the uncompressed digital pcm surround sound format is much less common and somewhat new. I have been testing all different kinds of media after getting my 5.1 configuration setup in windows hoping to hear ... anything out of those satellite speakers--nope. there is 1 single thing I found that actually had that pure unfiltered, high quality digital PCM HDMI 5.1 sound--an awesome game called final fantasy xiv online - a realm reborn. and probably a few other new games too. and maybe audio dvds. not sure what else.
for everything else you actually have to set your sound in windows to STEREO. right click sound icon > sounds > playback tab > select 'default device' > click configure. click stereo > next > next > next > finish. YES STEREO. why? because analogue component has been abandoned for the new and far more prevalent digital hdmi so older things are now sent through two channels into a compressed format encoded with multiple channels, which is then decoded in your AV receiver when you hit the dolby/matrix/whatever button. nobody buys sound cards with component outputs, especially since GPUs now output hdmi at increasingly larger bandwidths capable of multiple channels (after some compression). and subsequently, manufacturers are abandoning "higher quality" component inputs on their AV receivers for better and better and more hdmi inputs (my new onkyo has 4 hdmi in and 1 out, all hdcp 2.2 4k ultra hd ready).
so to recap:
if you ever find a 5.1 PCM source LOL... CONFIGURE WINDOWS FOR 5.1 SOUND in default sound device (and for me I have to hit the direct option on remote so it's not adding any weird surround sound filters etc but I think even if I did that the pcm signal would override not sure..)
and for everything else / older games / youtube (aka if you notice sound not coming from your satellite speakers when it says that sh!#'s supposed to be surround)--CONFIGURE WINDOWS FOR STEREO SOUND in default sound device (and then hit the surround/dolby/pro logic/matrix whatever button on your remote to hopefully decode it). GOOD LUCK <3
I hope this begins to answer anyone's questions this has been plaguing me for years and I finally figured it out since my old av receiver burnt out lol. I hope these hardware manufacturers realize it just makes them look stupid when their products fail as advertised yet there are such simple yet elusive software fixes / configuration options that must be selected in order to get the most (or anything) out of thousands of dollars of hardware. it's 2016 make this crap automatic! we shouldn't have to scour forums for hours/days/years to get such common problems working right.
I am sure I have some inaccurate info somewhere in here I have learned more than I ever cared to know about how audio is fed from pc to av receiver to speakers in the past few days getting this crap to work... this was just the solution that worked for me. please feel free to correct me / make this more accurate / add to this. thanks!
p.s. another issue I had was that when I applied an EDID hack to force my passive 3d LG tv to be recognized by NVidia 3d vision, it took away my surround sound formats/options. I finally figured out how to fix this too
