Issues with 5.1 Surround Sound with Windows 10

Not really an answer. Dolby is the industry standard in both movies and music. I do understand what you are saying when you ask whom for certain services. Example netflix.  You get 5.1 in the app....but not in a browser....unless you add come coding in the browser....so it works fine for me now without the app.  Now if I only watch Netflix that would be nice....lol.  maybe I will after Susan Rice is no longer on the board.  If it is 5.1 encoded it should play 5.1. I don't know if it is even a microsoft issue....or care. I just want it to work.  It often doesn't.  DVD's, music cd's always play 5.1.  Downloaded content even though it should because it is 5.1 encoded (I can see the coding) doesn't. Just looking for a possible fix.

The music encoded with 5.1 by WHOM. They will provide you with an app player playing the music with 5.1. If it is a streaming music service, then that streaming music service will also provide you with an app player.

Every thing works in test. Everything works watching a dvd.  I have the latest codecs.  I built the computer. It decodes Dolby...etc.....  When streaming or playing music that has been downloaded it is in stereo. Just trying to find answers on that. The stereo playing items are encoded with 5.1 but won't play 5.1. Just trying to figure out why. I freely admit I may be missing something simple. Just reaching out to see what I may have missed. As a side note I mentioned I used to be able to "fill" but that driver seems to be a windows 7 deal.

1. "Speaker Fill" (aka stereo upmix to 5.1) is a "feature" in the Realtek driver that is enabled or disabled by your computer manufacturer. Nothing to do with Microsoft.

2. Testing digital optical with test signal --- is testing whether or not your AV receiver can decode Dolby Digital or DTS. It does not mean your computer can decode encrypted Dolby Digital or DTS.

Whoops, I clicked the wrong button -- it did not solve my problem.         Starting problem is no sound from Netflix App but all good if I use browser for Netflix.   That got me to the Sound settings in windows 10 and the speaker setup.

I tried the suggested method. No luck.   I get test sounds only on the stereo option.   I am running through a receiver and the sound tests works for all the speakers(5.1) when i do the receiver  tests.

     I uninstalled an reinstalled drivers etc. no luck.  I am using a Nvidia graphics card so that may be an issue.

but, back to the sound test,  i do not get any sound from front speakes in the 5.1 selection.   On another computer i will get sound from the front speakers in the 5.1 setting even though it is not 5.1?
