The test starts by playing frequencies that are in your hearing range, and then they will steadily increase. As the sweep enters ultrasonic range, the sound will fade away. Listen carefully; the rest of the file should remain perfectly silent.

1. Next, click the Speaker Phase Test to make sure you didn't mix up the negative and positive connections when plugging in your speaker wires, If they're plugged in correctly, you should hear a difference in sound midway through the Phase Test.

There are many forum threads around the web about Windows 10 breaking Surround Sound / 5.1 DTS / 5.1 Dolby, etc.. However there appear to be a few different possibilities, and while some noted to fix it using unlocked Realtek drivers, I have tested this myself with the following results.

BACKGROUND

See screenshots below of all of my settings screens:

Windows 10, PC connected HDMI to my Samsung TV, and digital optical out through a Realtek soundcard to my Pioneer receiver (DD and DTS capable).

PC is a SHUTTLE SH67H3 PC

I have tried Realtek's R2.79 drivers Win10 x64. I have also tried the WIN10 x64 drivers from Shuttle's site (linked above). Both don't actually show the DTS/DD output option. The unlocked R2.79 drivers DO show that option, but more info on that below.

Wake up kids. My kid hates getting out of bed. I don't blame her; I do, too. We wake to a list of chores—shower, dress, eat, pack, go! Getting a kid up and at 'em can be super. Aug 6, 2018 - Parents don't need a special wake up alarm to make kids bright-eyed and bushy-tailed, but they may have to become a morning person themselves. After figuring out how to put a child to sleep, which is by no means a simple process, a parent’s next task is to devise a strategy for.

This worked in WIN7 without any headache, and using the built in drivers WIN7 applied to the soundcard. Didn't even need the realtek drivers.

Just use HDMI to your TV, and back to the receiver you idiot

Wouldn't that be nice! HDMI goes through the Samsung TV in full 5.1 glory, but the Samsung TV will not output it back out to the receiver in the same format it got it! It sends it back to the receiver as 2 channel.

Just use HDMI switching on your receiver instead you idiot

The receiver does NOT like the samsung TV as a single output. I get resolution issues, flicker, refresh rate problems, the list goes on. It is a far bigger headache to try and get the video to work right when putting all inputs in the receiver, and I decided it was time to let the TV handle all video itself.

And again, this DID work on WIN7.

TEST

My tests are always using a test DTS 5.1 file which plays sound in each speaker one at a time when DTS 5.1 is active and working properly. I have an MKV version which is also on PLEX (which plays through a browser).

PROBLEM

The below is true for either official Realtek driver file, and the built in windows 10 drivers (before realtek was even installed).

• Windows Movie and TV player, and Windows Media Player output NOTHING. No sound. Likely due to a codec issue though..
• VLC, with S/PDIF pass through disabled, output is 2 channel only. It is not DTS 5.1 or DD 5.1. The test file plays sounds only in the front L/R speakers one at a time as it cycles through all 5 speakers. When it gets to LTE channel, nothing plays at all, silence.
• VLC, using S/PDIF pass through option, works flawlessly and outputs DTS or Dolby Digital 5.1 sound through the optical output on my PC, to my receiver. Each speaker has it's own channel and the test file works flawlessly.
• Plex, in Chrome, IE, or FF, is never outputting DTS or DD 5.1. I can confirm that it is playing 'original' file and there is zero transcoding taking place. I've tried tons of plex settings, nothing seems to work. This is just like VLC with S/PDIF pass through DISABLED. I get 2 channels only and LTE doesn't work at all in the test file.
• Websites in Chrome, IE, FF are just like the above, no change. I cannot get DD or DTS to be output.

The below is true for the unlocked realtek R2.79 driver.

• I can go into the Realtek settings screen and now from the dropdown select DTS or DD. All of the sudden my receiver is showing DTS or DD on the front panel, SUCCESS!?!? NO.
• In fact, it is outputting DTS/DD. But it's not treating the files right. Just like in all the tests above, I cannot hear the LTE channel in the test file in any test, and the rear/center speakers are made only accross the L/R front speakers.
• What's worse, the S/PDIF passthrough in VLC now does the same thing, it no longer functions properly!!! So even though it says DTS, and it very well may be outputting that, it is downmixing everything it gets into 2 channels only!

So this is the problem, and I have found no solution to date. I am all ears. My goal is to get at least one browser capable of outputting 5.1 in DD or DTS in its true form. From Xfinity TV webapp, Plex, HBO Go, and Netflix at a minimum.

I've just spend whole Sunday solving this crap! But after all those hours I have a working 5.1 audio on Windows 10 (1809) through optical S/PDIF on my ASRock X470 (Realtek ALC1220). And it's not just DTS pass through!

There are many VERY VERY LONG threads discussing this, the most useful comment was this one.

The solution:

1. you need to download that patcher that will 'fix' the missingfeatures
2. download proper driver, that is still compatible with the patcher - in my case I've used version 2.82, the file name is '0009-64bit_Win7_Win8_Win81_Win10_R282.exe' (this is a two years old driver!!! I've tried to use official one for my MB but the patcher didn't worked)
3. unzip this .exe file to access the files and patch two .dll files in the 'WIN64' directory
4. install the driver - here you will get a warning from Windows that the driver is not signed!
5. reboot and finish configuration in the 'Sound' window:
   a) on the tab 'Enhacements' check 'Disable all sound effects'
   b) on the tab 'Advanced' for 'Default Format' select 'Dolby Digital Live (5.1 Surround)' - FINALLY!!!

If this feels like too much, here is the fixed installer (you still need to do the step 5 and execute the patcher - it needs to modify your Registry as well).

PS: Testing video file.

NOTE: The patcher gets some false-positive detection. But it doesn't require elevated rights to be executed and it's 4 years old. So I would say it's quite safe.

im using a intel NUC wich has hdmi and optical out.The only way i could get surround from the optical was disabling hdmi audio (intel audio in my case in device manager)reboot and done!Im in win10 using vlc.

Hi All,
I am trying to create a few video files for testing of a bug in the implementation of the XBox One's audio subsystem.
https://forums.whirlpool.net.au/forum-replies.cfm?t=2239812
So I would like to make some test videos which can be played back on the XBox One via Plex media centre or equivalent. I would also like to play them back on a range of other devices like a PS4, chromecast etc..
I want to make them something like this
https://www.youtube.com/watch?v=zYfqaWSZiuk
However obviously I can't upload anything greater than 2 tracks to youtube as I don't think it supports it. So I was just going to convert into an mp4 and play back by streaming to the XBox One.
So I would have each of the speech events go to the relevant surround channel/speaker.
I was then going to have white noise play for 3 seconds on each channel one by one in a circle moving from
7.1 channel - left front -> centre -> right front -> right surround -> right surround rear -> left surround rear -> left surround
5.1 channel - left front -> centre -> right front -> right surround -> left surround
Pro logic II - left front -> centre -> right front -> right surround -> left surround
I made the audio files

I pulled them into Audacity and followed these steps but didn't really get anything useful. I made flacs and wavs but nothing seemed to work.

Nothing came out of the surround speakers even when I tried various combinations of where to put the channels

I then mixed them into various combinations but nothing seemed to work when played back on the amp.

Does anyone have any suggestions for any opensource software that can help or to steer me where I am going wrong? I am only trying to make some test files so don't really want to fork out any cash.
I also tried to mix this audio into a single picture video using avidemux and got pretty crap results too with nothing working.

Excuse the cat I just went with the first picture I found and was not expecting to put it up publicly.
Ideally when I get this working I would love to have the following video files

• MP4 Container video with 7.1 DTS Audio
• MP4 Container video with 7.1 Dolby Digital Audio
• MP4 Container video with 5.1 DTS Audio
• MP4 Container video with 5.1 Dolby Digital Audio
• MP4 Container video with Prologic II audio

The video image can just be a static image displaying what format the audio tracks are in.
Can anybody steer me in the right direction please?
I even wouldn't mind extending this further by playing the sounds on simultaneously on diagonal speakers to see how the pro logic II handles this.
