Unlocked Realtek HD Audio Drivers Windows 7 & 8 (With Dolby Digital Live and DTS Interactive)

[McFly]

Just want to confirm that the A1 hack is also possible with the latest WHQL drivers (v6.0.1.7673) from 24th November.

Cheers!

Thanks, I will try because for far my results were not great. Any detailed process of how you achieved that? Would be very helpful for many!

Cheers

It seems to me that, even after the Windows 10 fixes, Witcher 3 surround sound through optical is not working. TF2 and movies on VLC player work, but not Witcher 3. Anybody get the same or have a workaround or are we going to have to try to get Microsoft to fix it again?

Edit: Oh, it turns out it's an old bug with Windows and xaudio2 that has reemerged with these changes Microsoft has made. Look up the xaudio2 Dolby DTS surround sound fix. It's also earlier in this thread a couple times, and you can find it multiple other places.

does this dolby thing works with a MB without optical or digital port? If so, how to conect to my 5.1 receiver ?

Thanks again, dts/dolby digital working through optical and neo working on 3.5mm jacks .

Well that's the only way to get a digital output and it's through optical or coaxial but you can hook up to your reciever with a RCA female to 3.5mm male.

so... 5.1 only with optical right?

the adapter will only give me 2.1 right?

Yep but you may be able to set 5.1 or even 7.1 in realtek's audio manager but it wont be true DTS/Dolby 5.1/7.1, that's how im using my current headphones, their stereo and all but the 7.1 is being emulated quite fine .

If you had optical/coaxial you'd get Dolby/DTS and PCM 96Khz.

 

[Irenicus]

I just signed up to this forum because I had to say a big THANKYOU YOU ROCK to those responsible for making this possible. I got things working on my 2nd attempt and worked out all the options failry quickly being quite tech-savvy myself

I've always just used analog 7.1 input for my receiver when playing games, but then when I watch movies I have to switch source. Not a major annoyance, but also the increased sound quality and dynamic range is well appreciated.

Being a musician and audiophile with a rather snazzy home-theatre system (Pioneer VSX-D811 and ATS Aaron speakers) I love good sound and taking advantage of the equipment I own


For what it's worth, I came across this thread while looking at information regarding surround issues with The Witcher 3 which I'd just bought. I didn't realise this pertained to DDL/DTS Interactive, but I am happy I found my way here

For anybody who's still having issues getting some games to work in surround, despair not. There is an easy fix.
Download https://drive.google.com/file/d/0B5r9wJYwSwdhMW1oSW5Ob2pZOU0/view and follow the instructions (works for all games. For example I just tested Fallout 4 and this fix works for that game also)
Ignore the instructions about copying the bat files to your documents folder, instead do this :
-move the 4 folders to your C: drive
-move the 4 .bat files to the same location

Follow the rest of the instructions *(ie run the edited bat files) and you're good to go . In conjunction with the unlocked drivers found here, I had no issues getting it all to work

Thanks so much again for this thread!

Im using onboard realtek from my rampage IV extreme. It has the ALC898 codec and i managed to get driver version 6.0.1.7655. DTS and DD always tested under supported formats tab on all 5.1 channels but they never showed up under default formats tab until using the unlock dll, but they only test output stereo sound. Some games still output only 2 channels, like arma 3 for instance. Even after trying the xaudio mod it still doesnt work. The string you are supposed to mod int he xaudio files isnt even there to replace in windows 10. Im not quite sure the games that seem to be 5.1 are right either as using 6 channel inputs sounds more accurate. Here is a decent list someone put together of games that are surround compatible and some details about them. I cant seem to find anything that says a game for pc has dts or dolby sound, only console games seemed to be licenced. DTS has more bandwidth than ddl but LPCM has even far more bandwidth and a much higher sample rate then both. DTS interactive is 1.5mbits/48khz/24bit, Dolby Digital Live is 640mbits/48khz/16bit

Linear PCM, Dolby TrueHD and DTS-HD Master Audio have such high bitrates because they are lossless formats while Dolby Digital and DTS-HD are lossy/compressed. S/PDIF (either TOSLINK optical or Digital Coax) does not have the ability to transmit the amount of data necessary for more than 2 channels of LPCM, so Dolby Digital or DTS are needed.

There are only a handful of games that use Dolby Digital or DTS because in most cases for PC gaming it is very rarely used. Audio is going directly to headphones that are plugged in to a headphone jack or with multichannel audio directly to the speakers from the different channel outputs on the soundcards. DTS or DDL are also not needed if your GPU is connected to a receiver via HDMI that is able to process the multichannel LPCM audio, which HDMI has the bandwidth necessary for.

Dolby Digital Live and DTS:Interactive encode any audio on the computer on the fly, so it does not matter whether you are playing a game that supports Dolby or DTS; any audio is becoming compressed to Dolby Digital or DTS.

DDL will not make a game that doesn't support multichannel audio all of a sudden surround though, it takes the channels being used then encodes them to Dolby Digital. For example, if you go in to the game sound settings and set it on headphones or stereo, the audio will be stereo even with DDL enabled. You have to set the game audio settings to 5.1, surround, etc. However, if I recall correctly, I believe DTS:I will use DTS:Neo PC (which both make up DTS:Connect) to upscale stereo to surround, but it would sound better to have it encoding 5.1 audio to DTS-HD instead of stereo to 5.1

I find I'm pretty bad at trying to explain this kind of stuff, but hopefully that helped out a bit.

TLDR; HDMI w. multichannel LPCM is King. (unless you're getting in to Dolby Atmos or DTS:X - a whole other topic)

Hi guys, I've had to register the forum to ask you as I couldn't get anything to work.

Current SO: Windows 10 x64
MoBo: GA-Z68X-UD3H-B3 (rev. 1.3)

I've couldn't get 5.1 neither install Home Theater on my own so I've tried the unlocked drivers.

I've used this version:

Link: http://necacom.net/index.php/realte...-definition-audio-hda-version-6-0-1-7673-whql

And the A1 method.

It seems that it works during this test: http://prntscr.com/99pucf
But once I go to the advanced settings and try to test the DDL there... http://prntscr.com/99puix
Failed to test tone.

Anyone have an idea?

Thanks in advance.

 

[GunnzAkimbo]

Has anyone been able to get nahimic working with headphones?
The drivers label the headphones as 2nd output.

Hi i buyed the dss2 but i had to buy the adapter for the optical cable for my pc...now I put the r2.97 drivers with the r2.75 and all the install etc...now when i put in the adapter with the optical cable my pc detect it and ask me to choose beetwen line in,headphones,rear speakers...I choose headphones and then nothing happens,I put the 5.1 or 7.2 surround on my realtek pannel but no sound cuz I dont have the option of dolby digital but only the DTC option which is ON...I think that my pc doesnt recognize the optical cable so if anyone have a solution pls tell me..ty
My motherboard is FM2-A75MA-P33

 

[Dreathlock]

Where can i find the A1 method?

 

[ralfyguy]

BTW, 6.0.1.7680 released Dec 4th, installed and still working.

No. Dolby Digital can only pass-through a digital connection.

You can use your receivers and MBs analogue connections. Buy a RCA to 3.5mm connector. You will get PCM Stereo as default. But you can apply the "Dolby Prologic" feature on your receiver to up mix it to gimmick Dolby Digital.

You will need a mini-bar for SPDIF output for your PC:

and stick it here(only Coaxial):

 

[Gilimanjaro]

So the unlock worked for me, but a few games only gave 2.0 output instead of 5.1. That turned out to be a very different problem, and I found the 'fix' (work-around more like) here: http://steamcommunity.com/app/214490/discussions/0/598198356180308529/

Basically some games trust MS's Xaudio2 too much, and output 2.0. Someone patched the Xaudio DLLs so they work properly.

YMMV.

(games affected for were Eliteangerous and Alien:Isolation)

 

[nessGDL]

The unlock worked for me without any problem at all! But before I share the details on how I got it to work (and hopefully help someone somewhere with a similar setup to mine) I'd like to thank the OP and all of the members here for sharing their time and methods with the rest of us (myself not being a very savvy user) it amazes me how everyone here is so willing to help others, thanks a bunch OP and thanks a bunch everyone!

Ok, on to my story, before I found this thread I was seriously considering purchasing a creative sound blaster X-FI pro sound card JUST so I could get my non DTS/Dolby media content as well as games to output decent surround sound to my Logitech Z906 speakers using the DDL and DTS connect features that come with the card's software, I am glad of course that I found this thread completely by accident given that I was looking for a way to install alternative drivers to the Realtek ones (never did that)

Ok, so these are the specs that I find relevant to the whole process:

• The PC where I installed the unlocked drivers has an MSI Platinum K92 board on which I always strictly used the onboard audio (it comes with 6 analog channels and an optical output port) I believe it was running ALC888, not sure what version driver but I don't ever recall installing anything other than the drivers on MSI's support page.
• Windows 7 SP1-64 bit Professional version
• Logitech Z906 speakers hooked up to the PC using an optical cable
• Kodi as my media player with all relevant LAV filters installed as well

This is how I got the unlocked Realtek drivers to work on my system:

1. Googled Realtek 2.71 drivers for my Windows version and chose to dowload them from Guru3D.com (Official Realtek 2.71 drivers)
2. Considering the Windows version that I run, downloaded the proper unlocked Realtek drivers using one of the links provided by the OP (The ones that say R 2.71 M1)
3. Extracted the contents of the official drivers (the ones from Guru3d, they came in a self extractable 7zip file) in my downloads folder, which in turn left me with a folder containing everything I needed to set up the official drivers.
4. Extracted the contents of the unlocked Realtek drivers (the ones the OP provided) to my downloads folder and opened the folder that contains the .sys file for my windows version (RTKVHD64)
5. Located the .sys file to replace (RTKVHD64) inside the official Realtek driver download which is in the Vista_Win7_Win8 folder and then inside the Vista64 folder and removed it. (You can move it somewhere else, delete it or make a copy/rename it just as long as it doesn't stay in the folder where you found it with the same name)
6. Take the .sys file found in the "unlocked Realtek drivers" folder from step 4 and move it/copy it to the Vista64 folder where the original RTKVHD64 file was, now the modded installation package is ready to be used.
7. Run the uninstaller for your present Realtek drivers. (feel free to use driver sweeper and add any additional steps relevant to the usage of the program if you wish, I simply uninstalled the drivers and then restarted the PC, might not be a good idea for most, but for me it worked just fine skipping to the next step after I uninstalled the Realtek drivers I was using at the time)
8. Reboot your PC and disable the driver signing feature by pressing F8 BEFORE your OS boots, that option is one of the last ones in the list that shows up I believe. Your PC will now boot into the OS.
9. Install the modded installation package using the "setup" file inside the Vista_Win7_Win8 folder.
10. On the prompt where windows tells you about the unsigned driver click on accept/ok
11. Reboot your PC again, but be sure that you once again disable the driver signing option by pressing the F8 key before the OS boots, you HAVE to do this everytime you start/reboot your PC, otherwise the unlocked driver will not load and you'll have no sound.

Now you should see the Dolby/DTS options in the Audio Manager window and set them to your liking.

If having to disable the driver signing option before the OS boots everytime is too annoying you can look into enabling test mode like the OP said.

I hope this helps someone somewhere!

ZAudio2.dll works great on Dirt Rally, thanks really for this solution.

And to make it simple, don't try to copy folders from here to there or run .bat files.

Just copy edited .dll files to your windows sys32 or syswow64 directory depending on which version installed, and that's all!

 

[GunnzAkimbo]

Only problem left is getting MSI Nahimic working with headphones, as the driver is not compatible with Nahimic, seems limited to original drivers only.

yap ! I can confirm that and I think it has to do something with ENHANCEMENTS which conflicting with DTS/DDL so drop it its shit anyway . Creative Cinema 2 was way better and kill me if I know why msi shifted to that utterly stupid NAHIMIC crap

 

[CarbonKid]

Hi there,

I decided to install this unlocked drivers, and used the A1 method. Everything was working fine and the games were outputting 5.1 to the receiver.

Except, the computer started to give me BSOD erros every few hours, does this happen to anyone? The windows dump, from the error, says the driver in fault was "ntoskrnl.exe" and caused by the adrees "ntoskrnl.exe +142460"


I've used the 2.79 drivers from realtek and the unlocked 2.75 A1


Can anyone help me?

 

[dvojinov]

negative here!
