    Yes my setup is using spdif optical since my receiver only supports optical input. Just wondering how were you able to make DDL work the first time then.:banghead: Well at least (I assume) DTS is working fine for you. There was another modded driver I came across before I saw this. You might want to have a look and try this:

    If you report an issue, please include:

    - OS (including whether it's 32 or 64 bit)

    - HD Audio Codec Hardware ID (Device Manager > Audio, Video and Game Controllers > Realtek HD Audio Controller, right click and select properties, under the Details tab select "Hardware ID", you can use Ctrl + C to copy the Hardware ID.

    - HD Audio Controller Hardware ID (Device Manager > System Devices > HD Audio controller). if you have multiple HD Audio controllers just post the IDs of them all.

    I couldn't get it working on an optical connection DFI board with ALC889 on Win7x64.

    Same issues, no playback, errors popping up about non working enhancements.

    Tried both 2.71 and 2.72.

    I'm gonna try it on my other machine next, which is a THX certified MSI board on an HDMI connction.
    edit: nvm, HDMI is a whole different beast...

    alas, same problem on that board, "test tone unable to play" etc... ALC887 was the chip on that MSI board.

    Transient positive glitch, it seems.
    Thanks for mentioning the Gamespirit mod, did indeed try the newest version of that though appears to be incompatible with the ALC1150, at least it could not install due to incompatibility, the installer prompts such an error and aborts. Unfortunately, DTS is a no-go for the ancient Creative Inspire 5.1 Digital 5500, only does old Dolby Digital; TOSLink port all busted too, suppose it is not exactly the finest craftsmanship but it was not exactly expensive either way back when.
    Good to know it works with your S/PDIF setup, though. Could you perhaps name the ALC chipset your sound card uses, for posterity (in case you have not yet done so)?

    Apparently due to PUMA (Protected User Mode Audio) Windows is (sometimes) making sure all user-mode audio dlls are properly signed,
    I'm not sure why and when, but for now I've posted my original modification (2.71 M1), which modifies the kernel-mode driver, and does not have this issue,
    unfortunately, if you use Windows Vista / 7 / 8 64-bit, you'll have to press F8 and select "Disable driver signature enforcement" before each boot, or employ one of the other alternatives suggested in the first post.

    Windows Vista / 7 / 8 - 32 bit and 64 bit - R2.71 M1:

    http://www24.zippyshare.com/v/34731542/file.html

    Alternative method:
    You're still welcome to try the alternative method (dll modification), which in some cases works:

    Windows Vista / 7 / 8 - 32 bit and 64 bit - R2.71 A1:

    Windows Vista / 7 / 8 - 32 bit and 64 bit - R2.72 A1:

    Care to be kind enough to share how it was solved (Or 2Bad)? I likely have the same problem(or similar), win7x64 ALC888S (i wonder what the S stands for...i doubt it's for surround).

    I get the enhancements are causing problems warning when accessing the playback devices.
    Headphones (Realtek High Definition Audio)

    My system is just a simple frontal analog output for headphones.

    At first only the Dolby Home Theater panel was avaiable through realtek's control panel (audio manager) after checking through windows playback devices the DTS panel was avaiable there and started appearing in realtek's control panel, although the options are accessible, enabling them make no difference whatsoever.

    Despite the "enhancements causing problems warning" the sound works as if they were the regular non-modded drivers on all formats (bit depth and frequency range).

    He sent me another mod, which causes another problem during startup (just an annoyance actually, not really a problem). I'll leave it to him to share the file.

    If ur just using headphones though why do you even want these? We are mostly just after DDL and DTS connect so that we get 5.1 through optical or coaxial output.

    Having pseudo/dolby surround even from plain stereo (or down mixed from 5.1 in some games that allow to choose it) through dolby home theater is better than nothing until the day i might get some kind of decent 5.1 or so surround headphones.

    Worked on my Asus p8z68-v pro gen 3 using optical out to a LG 7.2 channel HTIB and to be honest I can barely tell the difference from the sound blaster z I just purchased so it may be time to return it lol.

    I installed the latest drivers/mod and ran into issues when trying to test play back from windows device configuration but testing through the hardware included application I was able to hear sound and in BF3 when there is sound I can turn the player and can confirm the sound switches speakers as spin around. Windows shows I don't have DTS Connect or Dolby Digital Live selected when I know they both can be selected and afterwards I have seemingly true 5.1 surround sound.

    Just read BF3 uses the CPU to encode so the only real benefit for me is being able to send 5.1 surround over the optical output since I have a 144hz display and my HTIB only has 1 optical and 2 HDMI inputs I guess? I'm new to surround sound so the picture is still unclear to how this all works.

    if you're on analogue or HDMI this makes no difference. all it does is gives you 5.1 audio over optical or SPDIF (via DD or DTS) if your soundcard did not support that as a default feature.

    I didn't mention the HDMI for any reason other then to shed some light on why I am using DVI vs HDMI and benefit from the unlocked live encoding/compression since optical is my HTIB's only other input available besides HDMI and without the compression the bandwidth usage for 5.1 exceeds optical's specs.

    I have concluded that the "Failed to play test tone" issue is caused by PUMA (Protected User Mode Audio) detecting an unsigned user-mode DLL.

    Oddly:
    This does not happen after the DLL is replaced, and PUMA will only re-verify the DLL signature after a restart.

    I have updated the original post.

    btw,

    replacing the setup file with the M1 mod does not work. Setup fails midway.

    You have to install the original 2.71 and then change the file from system32/drivers directory.

    Just a heads up to save a few minutes of trouble ;)

    edit:
    If you are on the F8 mode I guess the installation will work too, haven't tried that.

    Thanks for the reply.
    I understand the part about the hardware being dormant but am unsure whether my soundcard has the support locked away. It may be a moot point since I don't do much with surround anymore and do not see how this would affect anything analogue e.g. headphones.

    Indeed these digital encoding features have no effect on analogue connections whatsoever, instead you might want to try the likes of Dolby Home Theater v4 for which hacks likely can be found on these forums as well, or even the currently free www.razerzone.com/surround/donate-and-download - naturally these only apply if you are not entirely satisfied with your current setup or if you are feeling adventurous and want to try surround sound emulation with headphones, as such software enhancements can be potential CPU hogs as well as introduce incompatibilities with other software which directly attempt to modify the audio stream such as audio decoders in some cases, though there is generally little permanent harm in trying them out and removing them if found to not be worth the bother.

    For those suffering from Windows PUMA (me) i found a sort of workaround.

    First rename the original dll to RtkAPO64.dll.org
    Then place the modded dll file into the system32 folder
    Create a .bat file containing this:
    Code:
    taskkill /f /im RAVCpl64.exe
    ren C:\Windows\System32\RtkAPO64.dll RtkAPO64.dll.Mod
    ren C:\Windows\System32\RtkAPO64.dll.org RtkAPO64.dll
    net stop audiosrv
    net stop AudioEndpointBuilder
    net start AudioEndpointBuilder
    net start audiosrv
    ping 127.0.0.1 -n 5
    ren C:\Windows\System32\RtkAPO64.dll RtkAPO64.dll.org
    ren C:\Windows\System32\RtkAPO64.dll.Mod RtkAPO64.dll
    CD /D "C:\Program Files\Realtek\Audio\HDA"
    start RAVCpl64.exe -s
    It shuts down the HD audio manager and stops the audio service, after that it puts the original file in place and starts the audio service. PUMA checks that the dll is 'good' and than after 5 seconds (ping) it replaces the modded file and boots the HD audio manager.
    This works and DTS and Dolby home are available (Dolby home tested and works)
    Used on an ASUS P5K PRO and ALC883 codec

    Hope this helps.
