    it's enough to delete all "audio converter" entries in the registry. I've spent less than 10 minutes to mod files removing converter featur from installation.

    Is it possible to reduce the latency when enabling monitoring on line in inside the xonar audio center. I have a Xonar Essence STX and when I have the monitoring button checked there is a slight latency. I have tried disabling all effects and DSP mode. (There seems to be less latency when Hi-Fi is on) I have tried changing my ASIO settings to as low as they can go. When I run a program such as FL studio or other recording programs. I am able to enable monitoring inside the program with no noticeable latency, but then all other audio on the machine is silenced. When I return to general windows the latency returns. Thanks!


    • Bruno Ferreira03 Jun 2013 @ 16:20

      As far as I can tell, that's by design. I came across the same exact issue as you did. The thing is, when using FL Studio or other DAW, you're using your soundcard in ASIO mode, and the latency will be whatever you specify.

      However, outside of the program, your soundcard is using the regular Windows drivers, which do have some latency from the inputs to the outputs.

      Having said that, you should be able to get good monitoring if you enable it *inside the Xonar control panel*, and not in the Windows control panel.


    • CarvedInside03 Jun 2013 @ 20:28

      I don't know of any method to reduce the input latency.


    • Mike Gibbons04 Jun 2013 @ 03:34

      Thanks for the replies. There's defiantly less latency when selecting it inside the xonar control panel although its still not as good as the asio one. I suppose I can just import the song I'm listening to into an ASIO program while needing the low latency monitoring. Hearing your voice delayed while speaking while gaming is a little irritating tho, but I'm just being picky πŸ˜›


  3. Benjamin Reilly03 Jun 2013 @ 16:03

    I've a question: is there a way to install your modified drivers by device manger getting it from ***.ini file?


    • CarvedInside03 Jun 2013 @ 20:27

      Don't understand what exactly are you asking. And its .ini or use .inf??


      • Benjamin Reilly03 Jun 2013 @ 21:39

        it can be possible to install drivers by their own folders dirctly by device manager, so I ask if it be possible to apply this procedure also to unixonar so to avoid all uselless software as control panels.


        • CarvedInside03 Jun 2013 @ 23:08

          While its possible to install only audio driver (see Possible solution 1), its pointless, because the settings, like default sample rate won't be set and driver will use 96KHz, and there are other settings that are only applied when the drivers are installed with the driver installer.


          • Benjamin Relly04 Jun 2013 @ 15:32

            it's enough to copy regedit settings key.... so to apply configuration. But it's true that a low sample rate decrease the latency but also the sound quality.


            • propheticus13 Jun 2013 @ 15:43

              Bullshit. If the cards native sample rate = 96KHz lowering won't lower latency. Also lower sample rate (44.1KHz) probably won't lose any quality (a human can hear). Also most music files are 44.1KHz (redbook cd quality)


              • Benjamin Relly21 Jun 2013 @ 12:40

                high sample rate increases latency because audio card has to compute sound using more resources.


  4. Hzu05 Jun 2013 @ 23:37

    Hello CarvedInside.

    First of all, thank you for such an amazing work. This driver saved my life from ASUS silly drivers. I'm loving this as it gives me better performance than before. But I have one problem, after switching to Xonar DSX, my microphone has started to pick up all the sound in my room (fans, speakers, voices from far away). This wasn't a problem at all when I was still using the on-board Realtek soundchip. The mic won't pick up sounds from my speakers, from fans, from voices far away. Just my voice, in front of it.

    I'm pretty disappointed with this card due to the proper lack of support for microphone as it is very essential for me (VOIP gaming everyday, and the software we're all using does not have voice detection method, and push-to-talk is just too hard for the kind of games we play). Even the on-board Realtek did a better job with their "Noise Reduction" and "Acoustic Echo Cancellation" functions (which they really worked).

    I've tried the AEC enabler by Virus, but there seems to be no effect at all, noises everywhere are still being picked up. I really need a solution to this, apart from wearing a headphones, because I don't like to wear headphones when gaming.

    Again, thank you for this driver and thank you for reading. I hope you (and others that are reading this) can help me in this situation.


    • CarvedInside06 Jun 2013 @ 13:55


      Some comments have to be approved, especially first time comments. It was a message letting you know after you've submitted your comment.

      I don't know of anything you can do to improve your mic on your Xonar. I personally don't have any problems, no one of my friends complained about background noise, so maybe your mic is aggravating things.
      One thing you could do is enable onboard card and use your microphone with it, and use the speakers with the Xonar card. You will have to set onboard microphone line as default in Recording Devices and if necessary change it in skype or the communication, while having Xonar as the default playback device.


      • Bruno Ferreira06 Jun 2013 @ 16:35

        Perhaps you didn't have microphone boost enabled before but you do now, and it's picking up everything?

        Just go to the Xonar control panel (not the Windows one), and on the microphone input there's a little button at the bottom, click it and disable/enable boost, see how it works out.

        Also, if you're using Skype, it usually has a mind of its own about what microphone volume should be used, so ensure that the "Automatically adjust microphone settings" (or whatever it's called) is disabled.


        • Hzu07 Jun 2013 @ 05:11

          With the Realtek, I have to turn the boost on or my voice wouldn't sound loud enough (vol:100%, boost: +30dB). Even so, the voice sounded clear and loud enough, and no background noises were picked up. I can confirm this as I actually did a few recordings to test out.

          But with the Xonar, it doesn't matter whether I turn the boost on or not, it'd still pick up everything. As for Skype, I've always disabled that feature and set my own volume.


      • Hzu07 Jun 2013 @ 05:05

        If that is possible, I might just use it as a last resort. Thanks for the suggestion. And perhaps you are right about my mic, as it's a cheap one after all.


  5. Michael08 Jun 2013 @ 07:39

    I just want to thank the creator of this project so much, You really make the life of ASUS cards owners much easier, as well as making the cards work at their full potential. You have done a great job, thank you. πŸ™‚


  6. Aldo08 Jun 2013 @ 21:01

    In case someone did not notice,, Asus just relaased a new beta yesterday! (the previous version was from 2011..)


    • CarvedInside09 Jun 2013 @ 17:51

      Which card?


      • Bob09 Jun 2013 @ 23:22

        Xonar Essence ST for Windows 7, Version: beta version, date 2013.06.07, only reports changes to the Russian and Japanese language πŸ˜•


        • CarvedInside10 Jun 2013 @ 01:09

          Thanks. Drivers are not as new as the date suggest, we have 1821 audio drivers in UNi Xonar 1.71.
          Those changelogs never provide the full list of improvements/changes.


        • MasterFaster10 Jun 2013 @ 17:42

          As CarvedInside said, there is nothing new. We already have the latest driver files.

          The 1821 ST/STX drivers include the same AsusAudioCenter, they just change the icon.



        • badsykes17 Jun 2013 @ 10:24

          I put a long post sometime before regarding the lack of support from Asus..By lack of support i meant exactly things like this...From 2011 no driver update for ST/STX series..Is there really nothing to fix in 2 years ? I realy don't believe this..I am feeling that Asus is pushing us to buy the new models. I still have some sound "artifacts" in new games.I am not using GX at all.Actually i have installed the 1.71 with C-media panel only..I don't want the Essence ST to become a gaming card but at least i want the correct effects reproduction or fixed...Explosions sometimes don't fade away correctly or fade away way to sudden when turning...
          Let's say i bite Asus wish and get the Phoebus:
          - i get a hope that being a new card i get latest fixes out of box and MAYBE more fixes for games
          - more updated drivers

          I lose on quality side...

          OR with C-media cards i have to leave with those problems ? I mostly play single player campaigns so no fancy tournaments and competitions to require fancy surround reproduction..


  7. Peter Roscoe10 Jun 2013 @ 12:39

    Hi All,

    Am I the only one who can't play anything above 44.1 kHz?

    No, I didn't think so!

    Right, WIN 7 64, J River v 18. Essence STX, just installed. Output to analogue amp.

    In J River, set to ASIO, 24 bit.

    When I try to play anything above 44.1 (FLAC) I get a droning sound like the slowed down vinyl.

    I have reinstalled the drivers ........ what on earth am I doing wrong here?

    Any hep gratefully received - I'm going mad here..


    • CarvedInside11 Jun 2013 @ 18:56

      In J River try switching the device to Speakers Asus Xonar device from Options->Audio->Output mode settings. You might want to try switching between the 2 Wasapi output modes. Hope this helps.


      • Peter Roscoe12 Jun 2013 @ 06:45

        Thanks for the reply.

        Last night I did that and tried WASAPI in J River - it works! Thanks. Also checked that the device was set to speakers (it was).

        So, after playing several hi res tracks in WASAPI, I changed back to ASIO and it worked for one track only (at 192k) but would not play the next at 96k ....... seems that somehow the card is not responding to the frequency change?

        Your support is much appreciated.

        I'm tempted to re install the driver but will await your advice!


        • CarvedInside12 Jun 2013 @ 12:31

          Could be something with the frequency change and possibly in relation to jRiver. Haven't had problems with foobar2000 with both ASIO and WASAPI.
          I'm not sure there is much it can be done.One thing I suggest is that you try the with previous UNi Xonar drivers (1.70, 1.64). I will try to look into things if I have more time and will let you know here if I find something.
          Anyway let us know of any developments.


          • Peter Roscoe15 Jun 2013 @ 10:28

            Trying to close this one down now.

            I completely de installed the UNI drivers, ran the driver cleaning batch file, stood on my head and whistled God Save the Queen softly.

            Then, reinstalled the UNI driver in safe mode.

            Result exactly the same - ASIO just doesn't work, but WASAPI does.

            From my limited perspective, the sound card is not recognising anything better than 44.1 kHz where it seems to be stuck.

            Does this make any sense?

    Xonar Essence STX for Windows XP 32/64-bits
    Version: beta version


  9. Delvan Silva10 Jun 2013 @ 15:57

    Windows Volume Mixer has problems with the Uni Xonar

    has no way to lower the volume in some programs

    Example: PES 2013, Winamp ..

    Please correct these problems

    thank you

    OBS: Sorry, I don,t speak English.


  10. Sonic11 Jun 2013 @ 01:09

    Hello I have xonar essence stx card and I downloaded the uni xonar driver. I have windows 7 32 bit on my computer. I have a question regarding the stereo mix. How do you get the stereo mix to work I see it in the recording tab but the green meter is not working when I play something on my computer. How do you get it to work?


    • Peter Roscoe12 Jun 2013 @ 11:34

      I'm going to guess here that the card is waiting for an input of either microphone or line in and doesn't pickup sound from the pc itself ......... but, have you checked in the Windows mixer?


  11. Tom12 Jun 2013 @ 10:15

    First thank you for your work, I really like the Uni Xonar Drivers on my Xonar DX.

    AFAIK the Xonar STX supports 176.4 kHz as well. Is there any way to make this available on the DX? I think they have the same C-Media chip.
    I have a couple of SACD-ISOs and would prefer to listen to them without upsampling to 192kHz.
    (At the moment I use analog out with wasapi on Win8 x64.)

    Thanks in advance!


    • CarvedInside12 Jun 2013 @ 12:22

      From my knowledge STX or any other Xonar card does not support other sample rates like 176.4 kHz. There is no way for me to enable it or make the drivers support this.


      • Tom12 Jun 2013 @ 12:54

        Well, based on the official specification, it is supported:

        And I found a review from 2010, which mentions its capability of 176.4kHz:
        "With the new driver, bit-perfect playback by the STX card is guaranteed at all sample rates supported by the DMA bufferβ€”44.1, 48, 88.2, 96, 176.4, and 192kHz"

        Link to the review: http://www.stereophile.com/content/asus-xonar-essence-ststx-soundcards-follow-september-2010

        (I don't want to argue about it, I'm just curious. πŸ™‚ )


        • CarvedInside12 Jun 2013 @ 13:49

          OK, from the review above, its mentioned that setting sample rate from the Asus Audio Center you are restricted to the usual sample rates. But if you use ASIO as output, it will correctly work with 176.4kHz. So if it works for STX with ASIO, then it should work with any other Xonar card that supports a sample rate that high. No changes needed as long as you use ASIO. But I don't know if it will work with WASAPI output.

          LE: After looking at the STX specs, I don't know what to think anymore. 176.4kHz could only be supported in ST/STX due to hardware differences, or it could be just that it is mentioned and updated only in STX specs and it is in fact working for all cards.


          • Tom12 Jun 2013 @ 15:06

            I have read somewhere if I play sound files with different sample rates with ASIO, the Xonar should make a click or pop noise while changing sample rate. I have tried it, and it really does, with 176.4kHz and 88.2kHz as well, but I'm not sure it is not resampled.


  12. Carlitos12 Jun 2013 @ 13:19

    Hello, πŸ™‚

    I want to know if you know that your drivers have problems with adobe flash player?

    I'm having problems with my browser, and I think after installing these drivers.

    Is it possible? Thank. ;D


    • CarvedInside12 Jun 2013 @ 13:54

      Don't know of any problems and so far no one reported.But sure, there could be issues. I suggest you do a driver clean and install the driver clean following the steps from FAQ:Q&A1. If it does not help in your issue try previous driver versions (1.70, 1.64).
      Let us know of the problems you have and if they where solved with the steps above.


  13. galaxia3d15 Jun 2013 @ 22:21

    Thanks for this awesome work.
    I just bought a Xonar STX card,and with the official drivers there was a horrible echo sound effect (like playing Battlefield 3 inside a giant metallic pipe).
    I did everything, disable onboard soundcard, Driver Sweeper, registry check, and nothing, but after trying your drivers every thing works fine. I did a normal install without c-media panel (because i was getting a glitch sound when opening folders on windows explorer).
    I hope this helps others who are getting this echo problem.


    • CarvedInside16 Jun 2013 @ 02:31

      Glad to hear. You have a 5.1/7.1 setup right?
      Regarding glitch sound, can you tell me your OS?


      • galaxia3d16 Jun 2013 @ 05:36

        Yes, i have a 7.1 setup using the Astro A50 headphones (on SPDIF), before were the Tritton AXPRO (using analog), but they died on me :(. I bought the Xonar STX so i could have Digital Dolby Live.

        I have Windows 7 Ultimate x64 without SP1 (Spanish).


  14. lumzi2316 Jun 2013 @ 16:47

    Is using this Software legal? (asks after already installing D':)


    • CarvedInside16 Jun 2013 @ 23:48

      You won't get in trouble because you are using it.


      • lumzi2317 Jun 2013 @ 20:51

        But is it technically legal?


        • Christoph Leipold17 Jun 2013 @ 23:24

          No its not! First C-Media provide the drivers to OEMs and make them available for getting modded or changed. Second is that the changes are more cometics as directly programming or changing the driver code. That leads me to the third fact that is the modded driver from Carved is provided for free. In most parts of the world you also allowed to mod or change your driver / firmware for personal use by law.


          • Christoph Leipold17 Jun 2013 @ 23:26

            Sorry i meaned " Yes it is!" ...technically legal to use this driver / software. Was in a hurry and missed the context πŸ˜‰


        • Hzu21 Jun 2013 @ 09:48

          Why not? You are just getting what you deserved more than what they gave you. As Christoph Leipold has said, the drivers were available out there to get modified and CarvedInside provided this for free. Nothing illegal is being done here.


  15. Derek18 Jun 2013 @ 19:06

    Will Dolby Headphone still work with these drivers? I'm not clear from this page http://maxedtech.com/uni-xonar-features/ if this feature requires Xonar Control Panel to be running and if so, that would obviously negate the advantage from the Low DPC Latency or C-Media Audio Panel versions.

    Is there somewhere I can download the Users Manual for the C-Media Audio Panel, as I don't have a Xonar myself but want to recommend these drivers to someone who does and need to be able to advise them on setting the options, etc so need to see what the panel looks like and understand the options for myself first?
