Release notes 1.81a

Driver for all supported cards. Includes 1825 audio drivers for Windows 10. Unlike previous releases, the 1825 audio driver will only work in Windows 10.

Driver changes:

  • Windows 10: Updated audio driver to 1825 (built date: 22 ‎June ‎2016, made by C-Media).
  • Updated C-Media Panel.

Other notes:

  • Replaced C-Media driver uninstaller with UNi Xonar driver cleaner.

Rev. 2 changes:

  • Added support for STXII cards in Asus Audio Center, cards will be detected as STX by Asus Audio Center but feature wise almost everything should be there.

Known issues:

  • 1825 audio drivers have an issue when the audio card is uninstalled, disabled or the drivers are overwritten, resulting in a system crash. In order to avoid the uninstall system crash I’ve come up with a workaround  that’s presented below
  • Asus Audio Center: GX button is no longer showing. It has to do with 1825 audio drivers and there may be a reason why C-Media removed it. I’m not sure if it’s worth it to bring the GX on/off control back.
  • STX II:  Asus Audio Center is missing the gain 16/32 ohms for headset.

Possible issues:

  • STX II: XonarSwitch might not work. Need more feedback on this.
  • Audio playback through headphones and SPDIF at the same time isn’t possible anymore. Original report. Need more confirmations.
  • DSX & probably other cards: DTS Connect with 5.1 speakers does not work. Original report. Need more confirmations.
  • There are reports that the sound quality of these audio drivers is different. RightMarkAudio tests that I’ve made didn’t show any significant differences between v1.81a and v1.80a.
  • The 1825 audio driver may have higher DPC latency than previous drivers. Original report. The tests that I’ve made didn’t show any difference in DPC Latency between v1.81a, v1.80a and v1.80b drivers. Maybe it’s has to do with the settings that are being used.  My test where done with 2.0 analog output.

How to uninstall 1825 v1.81 drivers: In order to avoid a system crash while uninstalling 1825 drivers you will need to play an audio file before proceeding with the uninstall process. Restart system after the uninstall process is done.


Release notes 1.80

UNi Xonar installer changes:

  • Added DPI interface scaling to the installer.
  • Added card autodetection and if the audio card is not detected it will show an error message with possible reasons for that.
  • Improved driver cleaning. It uninstalls all copies of the Xonar/C-media CMI8788 drivers that are present in the Windows driver repository. By installing drivers with “Run driver cleaning” option you won’t be able to use “Roll Back Driver” option for the audio card in Device Manager.
  • Changed the driver installation procedure. Added a fail safe driver installer that should help in those cases where you were required to manually install the audio driver or install it in safe mode. Silent installation is always on and its user option has been removed. If standard driver installation gets stuck (does not finish after 100 sec) it is automatically closed. If standard driver installer fails to install the drivers then an alternate driver installer is launched. If that fails too, you will get notified by the installer that driver installation failed.

Driver changes:

  • Windows XP: Added support for other CMI8788 cards.
  • Xonar DG, DGX, DG SI: Front Panel jack detection should now work if it did with the original drivers.
  • Fixed GX not being turned off by default in “Normal” configuration for the following cards Xonar D2, D2X, DG, DGX and DG SI.

Rev. 2 changes:

  • Improved and fixed some problems with the new driver installation procedure.
  • Added different messages based on why installation failed.
  • Fixed “Front Panel Microphone” not working by default.

Rev. 3 changes:

  • Increased the delay between driver cleaning and driver installation procedures. Might help in some installation failing cases.
  • Fixed the “Warning: Windows running in Test Mode or with Disable Driver Signature Enforcement is required!” message not showing up if needed in combination with the detected audio card.

The 1.80 drivers come in two variants:

  • 1.80a “Standard”

Driver for all supported cards. Replacement for 1.75a driver. Includes 1816 audio drivers for Win XP and 1823 audio drivers for Windows Vista/7/8/8.1/10.

Driver changes:

  • Windows Vista/7/8/8.1/10: Updated audio driver to 1823 (built date: 2 Jun 2015, made by C-Media).
  • Includes updated driver installer, ASUS Audio Center and C-Media Panel.

Other notes:

  • 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.
  • Xonar STX II cards: Drivers work with STXII cards but the changing audio settings may not work with ASUS Audio Center and only with C-Media Panel. Installation on Windows Vista/7/8.1/10 x64 requires Windows running in Test Mode or with “Disable Driver Signature Enforcement” option.

Known issues:

  • STXII: Asus Audio Center does not work. You need to download this patched version and copy paste it over “C:\Program Files\UNi Xonar Audio\Customapp\”.

Possible issues:

  • Microphone stops working if running specific programs. If you run into this issue please report it in a reply to the original report. If you run into the issue you can switch to v1.75a drivers or connect the microphone to the onboard audio card microphone input.
  • WASAPI playback issues might occur with some soundcards
  • Occasionally when waking PC up from sleep the Xonar card does not output any sound.
  • Drivers might stop installing on Windows 10. Try 1.75a, 1.80b or 1.81a instead.
  • Windows 10 Creators Update: Windows would not boot after these drivers where installed. If you run into this problem you have to boot Windows in Safe Mode and remove the audio drivers. Original report. I could not reproduce the issue.
  • 1.80b “STXII”

Driver maily for STX II and  STX II 7.1 cards. It does work for the other UNi Xonar supported cards too. Replacement for 1.75b driver. Includes STX II version 11.5 audio drivers (built date: 18 Feb 2014, made by C-Media).

Driver changes:

  • Includes updated ASIO (, driver installer, ASUS Audio Center and C-Media Panel.
  • Windows XP: Drivers now work for all UNi Xonar supported cards. These were not working with 1.75b drivers.

Other notes:

Rev. 2 changes:

  • Fixed “Asus Audio Center” not working properly and getting replaced by C-Media Panel when installing with “Normal – Asus Audio Center” configuration.

Rev. 3 changes:

  • Fixed some installation issues when drivers were installed on STXII cards (like missing driver uninstall entry in Programs and Features,  incorrect C-media panel name).
  • Fixed a bug where optimal card configuration was not being applied if the drivers were installed without the “Re-enable stereo upmix” option.

Possible issues:

  • Microphone stops working occasionally or when changing audio playback settings (DS->WASAPI). If you run into this issue please report it in a reply to this comment. If you frequently run into the issue you could try v1.75a drivers if possible or connect the microphone to the onboard audio card microphone input.


Release notes 1.75

UNi Xonar Installer changes:

  • Various changes and improvements done to the UNi Xonar installer.
  • Added warning message if installing the drivers would require Test Mode.
  • XonarSwitch is now automatically closed before installing the audio drivers.
  • Improved “Apply addons” function. Included .inf files from the drivers can now be dynamically altered. Documentation can be read here. Applying new 1.75 compatible versions of addons (like DHT4) will display the proper audio driver version now and users could now choose which addons they want to install once these are added to the Uni Xonar installer location.

Rev. 3 changes:

  • Fixed GX is not being turned off by default in Normal configuration for the following cards Xonar D2, D2X, DG, DGX, DG SI.

The 1.75 drivers come in two variants:

Rev.2 changes:

  • Fixed ASUS and C-Media Panels not working in Win XP.
  • Includes updated driver installer and C-Media Panel.

Known issues:

  • The installer is showing “Warning: Test mode to be enabled!” message by mistake if Xonar Xense selected as card.

Possible issues:

  • Missing Dolby Pro-Logic IIx options from C-media Panel. If you have this issue, you can use the “C-media Panel v1.62” installer addon or install v1.72 drivers.
  • 1.75b “STXII”

Driver mainly for STX II and  STX II 7.1 cards. It also works with UNi Xonar previously supported cards.

Rev.2 changes:

  • Fixed issue where installer did not apply the correct audio settings (e.g. to fix surround echo). Anyone who installed the previous 1.75b drivers should install the 1.75b rev.2.

Driver changes:

  • Includes updated ASIO ( , ASUS Audio Center and C-Media Panel.
  • Includes STX II version 11.5  audio drivers (created on 18 Feb 2014).

Notes about Windows 10 compatibility (updated 10 May 2017)

UNi Xonar drivers above v1.64 will work in Windows 10 but since the audio drivers are not yet made specifically for Windows 10 there could be some issues that you could run into depending on audio settings used. Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions.

Apart from driver issues there could be issues solely from Windows 10 sound system that would be fixed with future Windows updates. There is also a small chance that some things could break with future Windows updates.

Update 20 Apr 2017, 10 May 2017: Windows 10 Creators Update (build 1703) reported issues so far are:

Your feedback is welcome.  For those of you who run into severe problems after the Creators Update build upgrade you could roll back to the previous Windows 10 build (#1, #2). If that is no longer possible you can download an older Windows 10 build from here and install it without a internet connection present.

To prevent Windows 10 upgrade to Creators Update you need to either disable “Windows Update” service from Control Panel->Administrative Tools->Services or disable the Creators Update update with Wushowhide tool (guide on how to use it).

Update 30 Aug 2016: Thank you for the feedback so far. Based on the feedback received there shouldn’t be any problems installing the drivers on Windows 10 Anniversary Update (build 1607) whether it’s an upgrade or a new installation. One user reported that audio card was recognized only when installing the drivers when booting with Disable Driver Signature Enforcement option. Apart from drivers installation aspect, this new Windows build brings new problems for some users like the following reported ones: crackling or loud popping sound in the speakers, audio card not being detected sometimes or disappearing in Windows and 5.1 analog not working. For those of you who started having problems only after the Anniversary build upgrade you could roll back to a previous Windows 10 build (#1, #2). If that is not possible you can download a older Windows 10 build from here and install it without a internet connection present. To prevent upgrading to build 1607 you need to disable “Windows Update” service from Control Panel->Administrative Tools->Services.

Update 3 Aug 2016: Microsoft made changes to driver signature policy with the Windows 10 Anniversary Update (1607) that could make the Xonar drivers not working/installing anymore. There are some exceptions from this driver signature enforcement. At the moment it’s unclear to me if installing the drivers in Test Mode or with Disable Driver Signature Enforcement still works. I’m interested in hearing you experience under this discussion thread.

Update 28 Nov 2015: The Windows 10 Threshold 2 update does not seem to fix many of the sound issues that where present so far and it may introduce new ones. In my opinion Windows 10 is a very buggy OS, the only things working fine are the spying of its users(#1, #2) and the periodic removal of user preferences and programs(#1, #2, #3, #4).

Update 19 Oct 2015: The audio fixes from Insider Previews >= 10547 will probably be included in the upcoming “Threshold 2” update that will be released around November 2015.

Update 1 Oct 2015: The Windows 10 development team is fixing some audio issues with Windows 10. The fixes where made available for testing starting with Windows 10 Insider Preview build 10547.


100% compatible drivers when?

Because of the very slow development of the audio drivers by C-Media and the long time it takes for C-Media partners (ASUS and HTOmega) to release the new drivers it may take a while before we have a 100% compatible driver for Windows 10.  If we are lucky we will have new audio drivers in 2-3 months after Windows 10 RTM launch. As soon as new audio drivers became available I will release a new UNi Xonar drivers package.

  • Update 25 Jan 2017: 1825 audio drivers for Windows 10 are available. These are the first audio drivers that only work on Windows 10. Hopefully they will perform better than those that supported also Windows 7 and Windows 8.1.
  • Update 01 Oct 2015: 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.

About Chrome stutter issues on sites like YouTube. (27 Aug 2015)

  • Update 27 Aug 2015: The stutter issues on youtube are  fixed with the latest Chrome build released on 20 Aug 2015 (v 44.0.2403.157). Reports indicate that stutter issues are still happening for videos on other websites (eg. daily motion, facebook, instagram).
  • Update 7 Aug 2015: After some testing and some reading it seems that the stuttering issues are not related to the UNi Xonar drivers. I’ve got the same behavior with Realtek’s onboard audio and from what it looked liked. My guess the issue is caused either by Windows 10 or Chrome.

There is a Chromium issue opened here.

Here are some things you could try:

  • Change Chrome audio buffer size.
  • Change/keep sample rate to 44.1 kHz both in the audio panel and Windows Volume->Playback devices->(…) Audio Device Proprieties -> Advanced -> Default Format.
  • Change sample rates back and forward a couple of times.

    I haven’t heard anyone discuss this but how do I fix audio glitching? If a process plays audio and it is terminated in task manager, the audio drivers will freak out and constantly (and annoyingly) play the same audio frame until the computer is restarted. Enabling and disabling the audio drivers doesn’t fix this. I am running Windows 7 and it did this on Windows 10 too.

    I am currently programming something in C++ that involves the usage of an audio library and when the process itself is force closed the audio will freak out when currently playing something. To further prove that it’s the fault of the driver or ASUS device, it does not happen on any other computer that is running a different audio card.
    And this doesn’t apply only to my program, it applies to any application that has audio such as games.

    Any suggestions or fixes?


    • Jik    08 Nov 2016 @ 22:58   

      Well I just solved the issue. Disable GX.

      ->Audio Center -> bottom right GX button

      Don’t even know what GX is and it’s enabled by default. Turning it off doesn’t seem to affect audio quality but fixes audio glitching. Why is this enabled by default? Please fix that in a future update.


      • Falcon    09 Nov 2016 @ 01:31   

        GX is emulated EAX. Ya, it’s a good fix – to disable it. Because voice stucks on xonars ;//


      • CarvedInside    09 Nov 2016 @ 21:49   

        Which audio card do you have? Which driver version did you install?


        • Jik    09 Nov 2016 @ 22:36   

          Xonar DGX.

          I installed 1.75a and 1.64 because they were labelled as “recommended” and “stable”. I never bothered to try 1.80a but now that I have GX is disabled by default.


          • CarvedInside    10 Nov 2016 @ 21:03   

            I’m sorry, I should have updated the 1.75a and 1.64 driver packages to avoid this problem. I will take care of it. Thanks for the feedback.


  2. RyperX    09 Nov 2016 @ 16:47   

    Hey guys,

    i have a Question i am using a Xonar D1 and i think about to get an DAC/AMP.
    The problem is i wanna use the Dolby Headphone feature on the DAC. Is it possible to use the feature with the DAC?


  3. Roope Kiviniemi    16 Nov 2016 @ 08:43   

    Hi! I ordered Xonar DGX to replace my crappy unboard audio. I’m running Windows 10 latest build. So which driver version is most recommendet to use?


  4. Boli    18 Nov 2016 @ 01:11   

    Hello guys,
    I have a quastion. Can Dolby Digital live output DD ex format? For example if I watch a movie with a DTS-ES track (driver set to 8 channels), and I use Dolby Digital Live to transcode the audio stream into DD will the driver creat a DD ex stream? Will it actually use that extra 2 matrixed channel?

    UNi Xonar 1814/1818 v1.70 seems to be the stable one for me, later drivers seems to have a bug where Windows System sound are disabled while you are playing games. I can reproduce the issue everytime in my system. In 1.70 the issue never happens. I have been struggling my mind over 3 days to guess what the issue could be and it was the driver version.

    Btw thank you for the drivers and the support, they are awesome! 🙂

      Please give us details like which card do you have, your OS, if you’ve tried all the newer drivers up to 1.80a, which output are you using (analog or digital). If you can clarify as to which sounds aren’t working. Thank you.

    I have a Xonar DX with 5.1 speakers, and i’m using 1.80a drivers. I’ve installed C-media Panel.
    However, I can’t get my subwoofer to work and i can’t find any solutions online. I know that my speakers are ok since i tested them on a diferent setup. Center speaker is working fine as well.


    • CarvedInside    28 Nov 2016 @ 11:54   

      Hello. Which OS do you have? Does subwoofer work in speaker test? In which situation is the subwoofer not working, in 5.1 content(games,movies) or stereo upmixed content (music)?

    First off, thank you for your time and obvious support to an otherwise “dead” driver development/update schedule by the manufacturer. As good as your divers seem, I’d almost say that this was a manufacturers plan to take over the world by 3rd. party developers like you! Great work and a job VERY well done!

    Now, on to my issues. I am somewhat new to this. I am a gamer and a music lover (although not a full fledged audiophile). I have this issue on my DGX card in which I have everything installed and all seems to work properly. But I am encountering an issue in which if I am using Foobar with Xonar ASIO (64) (or ASIO4ALL V2 for that matter), if I hit the “Next Track” button, the song will change but I lose sound. So far I can regain my audio by simply switching back and forth between sample rates. This happens in the stock drivers (used before discovering Uni Xonar) and in Uni Xonar as well. So I am believing that it is either something related to the drivers themselves or my Windows 10 setup (all updated).

    Also, but I am lacking enough data on this issue, while playing a game for an extended period in full screen windowed mode the driver seems to switch the audio channel on its own. I see this in the ASUS Audio Center. This has happened to me twice in about 4 hours of play when using my headset (front panel) in that it suddenly loses audio and when I look at the ASUS Audio Center, I see that I am on some other channel (usually speakers) without my doing anything to change the channels up like that. I am suspecting maybe some sort of key sequence or something but as I mentioned, no ideas.

    I have read quite a bit here on your site but I have not been able to hit on anything that is helping me so far. I am sure that I am missing something (maybe a lack of understanding of a term?) in what I am reading. I thank you in advance for any assistance in this matter.

    BTW… am using the 1.80a driver.


    • Kahbrohn    28 Nov 2016 @ 12:12   

      UPDATE: I have done something in that now I am no longer seeing the first issue (sound loss + sample rate switching to resolve). The only thing I remember doing was switching back and forth between the two ASIO drivers that I have available to me (ASIO4ALL and Xonar DGX ASIO 64). I left it on the Xonar ASIO (“stock”) driver. I have not experienced my second issue yet but I have not been gaming (online) as long either. Will continue to check. Is there a config file or logcat somewhere with my present settings that I can save or print out as a reference?


    • CarvedInside    28 Nov 2016 @ 12:42   

      Hello. For the ASIO playback issue, you should check with WASAPI playback output. WASAPI offers the same quality as ASIO and might not have the bug. If you don’t want to use the WASAPI playback instead of ASIO, you should remove ASIO4ALL and also try with 1.75a and 1.80b drivers. The issues might be related to Windows 10 as Windows 10 and it’s updates brought a lot of issues that where never there with previous Windows OSes.

      Regarding the automatically changing channels while gaming issue. There aren’t any global hotkeys for ASUS Audio Center settings.
      If you get the issue you should reinstall the drivers with Low DPC Latency(and exit ASUS Audio Center after you use it) or C-Media Panel and see if you still get the issue. Also try with 1.75a and 1.80b drivers.

      Sometimes getting everything to run smoothly with Xonar cards take time and effort and it’s not always possible.


      • Kahbrohn    28 Nov 2016 @ 13:24   

        Thanks for the quick response. I will try as suggested and yes, I do agree, W10 is somewhat troublesome about running things. Getting things to run smoothly does take time. Fix one thing and something else pops up. But, at the end of it all, you do get a fully working product!

    I get a loud snap when switching from 2 speakers to headphones in Analog Out and also when switching any of the sample rates. Has this been resolved? I believe I have the latest drivers My sound card is the Xonar Essence STX PCI-E Audio Card, running Windows 10 64 bit, P8Z77-V Premium motherboard.
    Thank you,


    • CarvedInside    04 Dec 2016 @ 22:25   

      Hello. A low volume snap when changing some of the settings is considered normal. As for a loud snap, I don’t know what could be the issue. Try using C-Media Panel or XonarSwitch to change the cards settings and see if with those you don’t get the issue.

    Hi I have moved over to the latest drivers as the offical ASUS drivers are now dated and I’m trying to cure my intermittent DX issues.

    Sometime when I get to desktop I have no sound and a reboot is required and sometimes when I get to desktop the sound is distorted and buzzing/crackling/hissing! If I go into device manager and disable the card…then readable the DX then the sound is OK.

    Even with your latest build I’m getting the same issues on Win10 64bit (Anniversary updated)


    • CarvedInside    04 Dec 2016 @ 21:37   

      Hi. Thing you could try:
      1) Check that you cards EEPROM wasn’t overwritten.
      2) Make sure the power connector to the card is properly inserted. Sometimes the plastic from the power connector on the card is displaced outerly.
      3) Update motherboard bios.
      4) Try plugging the card in a different PCIe slot.
      5) Install drivers with “Low DPC Latency” or C-Media Panel configuration.
      6) Try other driver versions.

    Greetings. I am attempting to make a xonar dx 7.1 card function as 4 distinct stereo outputs for what will ultimately be 4 different zones for a music server.
    In order to get this to work I need some way of exposing these outputs to the system as if they were individual cards, ie virtual sound devices.

    I ran across a comment on a different forum that indicated the uni xonar drivers might be capable of doing this, but have been unable to make it work thus far. Is this correct? I have been able to do this with great success on linux using /etc/asound.conf but have found no equivalent solution for windows. Thanx!

    OS: Win10 x64
    Can’t remember uni driver version


    • CarvedInside    08 Dec 2016 @ 15:11   

      Hello. UNi Xonar drivers are not capable of this. You would need to search some program that allows creating virtual sound devices for Windows. Maybe this could work .
      There is also another way that would work and that is to configure the audio player to output to specific channels. For example foobar2000 along with Channel Mixer can do this. Note that with the Channel Mixer plugin you can output to only 3 instances(6 channels). Maybe there is a more capable plugin out there. If you want me to walk you through configuring foobar2000 with Channel Mixer let me know.

    Weird issue I’ve encountered on my W10 x64 machine ( xonar d2/pm, up to date drivers/windows )

    Music playing in the background (browser, was listening to an online radio), had some folders open and was scrolling through some pictures, left the pc for a couple minutes and when I came back and moved the mouse a little bit the audio stuttered/distorted for 1-2 seconds and then it was back to normal, its a 100% repro on my machine as Ive managed to reproduce it everytime.

    Any idea what might be causing this ?

    Is it possible to prevent HsMgr and HsMgr64 from running without messing up the drivers? These seem to cause conflicts with Malwarebytes 3.0. I have an Asus Xonar Essence STX on Windows 10 64-bit.


    • CarvedInside    10 Dec 2016 @ 22:18   

      Open “Task Manager” go to the Startup tab and disable HsMgr and HsMgr64. Then either restart the system or end the HsMgr and HsMgr64 processes from Task Manager Processes tab.

    Hi there,
    I stumbled upon your website while searching for the proplem I had after the mighty win10 ani update with my xonar d2x … the sound was off and only enabled after some sound effects were triggered, but this left half of the sound cut off in the initial second. And also the Asus mixer did not work any longer .. so I just gave this driver a shot and I must say … THANK YOU !!!!! 🙂
    finally my SPDIF connected device shows always on again and is using the correct speaker configuration again. So far no issues seen, thank you so much!


  14. paul    17 Dec 2016 @ 22:51   

    Correct settings and suitable drivers for digital using Xonar DG, Windows 10, Yamaha dspA1 5.1 set up.
    Your help would be much appreciated as I am going nuts , basically I want sound coming out of all speakers
    (not for gaming) Netflix/YouTube /audio/etc

      Xonar DG does not have Dolby Digital Live or DTS Connect encoding that would allow seamless 5.1 channels S/PDIF output. There is a solution but it is a little bit tricky.

      To play 5.1 sound over S/PDIF output on a Xonar DG or Xonar DGX your content(movies, music) has to be already encoded in Dolby Digital or DTS Audio formats or you must setup realtime DTS encoding with AC3Filter that would only work for some players. You need to use the the “S/PDIF Pass-through Device” which is available as a separate audio device that needs to be set in the video player preferences as the preferred output device. Before you start configuring the player you should test the playback of S/PDIF Pass-through in Windows Volume-> Playback devices-> S/PDIF Pass-through Device (Asus Xonar DG…). I’m not exactly sure how the settings in ASUS Audio Center should look like, if you leave S/PDIF output to PCM or disable it. If you try this please let me know if it worked and which settings you’ve used.
      Additional settings in the video player settings might be required (look for something like AC3/DTS pass-through S/PDIF).
      For realtime DTS encoding with AC3Filter you can follow this guide to which you need to disable most of the internal filters except DTS (probably). For NetFlix you should see if it allow you to select S/PDIF Pass-through Device as output, if it doesn’t then try setting “S/PDIF Pass-through Device” as default playback device in Windows Volume-> Playback devices. There is also a method of making a virtual output device with AC3Filter that you would use instead of “S/PDIF Pass-through Device” that you can view here.

      Other solutions if you can’t make it work with S/PDIF Pass-through: 1. Check if the onboard card has Dolby Digital Live support or DTS Connect and use that instead.
      2. Use the card’s analog outputs to connect to the receiver.
      3. Buy a card that has Dolby Digital Live or DTS Interactive Encoder (DTS Connect encoding).

        thanks for your help ive downloaded one of your drivers and there is a huge difference in sound thanks for spending the time to reply
