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 gave up on trying to get my Razer Barracuda to work in Windows 10 with your drivers (it’s Razer’s fault, not yours!), so I ended up buying an HT Omega Striker from eBay. At least HT Omega still support their cards unlike Razer. Waiting for it get delivered.


  2. Wroargh    13 Aug 2016 @ 16:43   

    I had no problems installing the newest drivers after anniversary update, but im struggling to hear anything from my speakers after listening music for 2-5 minutes, the volume gradually turns down and i have to restart pc or my speakers, either one seems to fix it randomly. Volume is perfectly fine on my headphones surprisingly.
    Im on windows 10, xonar stx, 1.80a r3


    • CarvedInside    14 Aug 2016 @ 22:31   

      You connect the heaphones to the same output as the speakers? Since you mention you restart your speakers (I assume switching them to OFF and ON again) your problem might be from the speakers. Try checking the speakers with another source (onboard audio card or mobile device).


      • Wroargh    15 Aug 2016 @ 21:38   

        Yes, switching the speakers on and off is what i did. The speakers are connected to the audio cards RCA jacks, while the headphone is plugged on the headphone jack. For now i just keep my volume maxed out since there is very little to no point to keep searching for a solution (yes i spent a couple of days looking for a possible solution) and the speakers still work great, its just i have to keep my volume maxed out if i want to hear anything at all.


  3. Madrac    14 Aug 2016 @ 17:40   

    Front panel microphone doesn’t work at all in Windows 10 x64 (not anniversary), in version 1.75 nor 1.8 (1823).
    I installed it with C media panel.
    Connecting mic to soundcard directly is working.
    Under Windows 7 it worked flawlessly.


    • Madrac    16 Aug 2016 @ 18:00   

      It’s working now. Don’t know what happened, maybe just a plug contact issue. Apologize for that.

    Updated to W10 x64 Pro Anniversary Editions, I have no issues at all on Asus Xonar D1 with UNi Xonar 1816/1823 v1.80a r3 driver (GUI: Xonar Audio Center).


  5. Ahmed    14 Aug 2016 @ 21:01   


    Asus Xonar Xense
    UNi Xonar 1823 v1.80a r3
    Windows 10 Anniversary update.

    I updated Windows normally, after restart the driver is still installed and seemed to work fine.
    I get a lot of crackling and loud poping sound in the speaker, specially when I’m seeking a video in a windows play or in a browser.

    Any work around for that?



    • CarvedInside    14 Aug 2016 @ 22:28   

      Hi. Try uninstalling the drivers and installing them again. Try installing with “Low DPC Latency” or “C-Media Panel” configuration if you’ve previously installed with Normal configuration.


      • Ziddy    18 Aug 2016 @ 06:30   


        I can definitely say something is wrong with the driver or with the anniversary update.

        I’ve been testing alot and for some reason when a certain app (i.e foobar2000) goes above a certain dB (the easiest way I explain, just put the volume at max in foobar and use a loud song) the sound crackles and at one point at extreme levels it becomes distorted. It sticks like this on 99% of the cases until you restart and then the distortion/crackling is gone temporary (sometimes it comes back after a minute, sometimes within 10 seconds). It has never happened before the update. I’ve also tested with ASIO (just to make sure whether its something else) and everything works perfectly fine there. I’ve also intentionally tested on a Windows 8.1 clean install (using a different drive) and nothing is wrong there either.

        Using UNi Xonar STXII 11.5 v1.80b r3 as the driver. Low DPC Latency or any other configuration doesn’t help. Reinstalled Windows 10 3 times (with the anniversary update included since you can’t get an older version, sadly).

          Thanks for the feedback.

          You can download a older Windows 10 build from here. Install it without a internet connection present and once installed disable Windows Update service from Control Panel->Administrative Tools->Services.

      What did you upgrade from? Win10 or win8/7? I already had piss poor, insuferable latency starting with RTM (until I downgraded to win8.1). So they made it even worse? That’s “genious”…

      I guess I’m going to pass on win10 completely…


  6. Aidan    17 Aug 2016 @ 05:43   

    Try as I might I simply can’t get either 1.75b or 1.80b STX II drivers to install without that annoying “Hata: Region unload” box popping up. I had a fresh install today and I remember having this problem and somehow fixing it, but google yields no help this time around.



    • CarvedInside    17 Aug 2016 @ 12:42   

      Here is your past comment about fixing it. You could use C-Media Audio Panel or XonarSwitch instead of Asus Audio Center and that way you won’t get the “Hata: Region unload” error.


      • Aidan    20 Aug 2016 @ 19:39   

        Interesting. XonarSwitch seems to have done the trick, although it was a bit confusing at first as I uninstalled the asus drivers but didn’t install the UNi drivers (derp), but now it makes sense! I am a sucker for the asus interface though, but I can deal with it 🙂

        Thanks yet again 😀

    Hi, thank you for this amazing drivers.

    Driver UNi Xonar 1823 v1.80a r3 works in a Windows 10 upgraded to Anniversary Update. The only problem is that the Audio Center don’t load in Windows start up, but loads if I run the application.


    • CarvedInside    20 Aug 2016 @ 18:57   

      Thanks for the feedback. Regarding Asus Audio Center not starting at Windows start-up, did you by any change install the drivers with “Low DPC Latency” configuration? If not, can you check for the presence of “CmiCnfg Dynamic Link Library” in Task Manager->Start-up and tell us if it show there and if it shows as enabled or disabled.


      • Diaboliquin    25 Aug 2016 @ 00:18   

        Thanks for answering. Yes I have the Low DPC latency configuracion. I will test the normal one.


  8. IJOJOI    19 Aug 2016 @ 16:46   

    Hi, unfortunately something doesn’t work with with Windows 10 + Anniversary Update.
    I just got myself a Xonar DG, deleted all the realtek stuff, deactivated it in the bios, and installed the DG.

    ASUS drivers didn’t even install, saying that there is no DG card.
    I installed version 1.80a r3, with the C-Panel, everything fine sofar, but there is no sound coming out 🙁

    Have tried several reinstalls and so on, but still nothing…

    Furthermore I wanted to add, that the “normal” install with the ASUS interface doesn’t work because I can’t start the Interface doesn’t show up…


    • CarvedInside    19 Aug 2016 @ 18:29   

      Does the 1.80a installer show any error message when starting? On the second page, does it detect the Xonar DG or do you have to manually select it?


      • IJOJOI    20 Aug 2016 @ 02:16   

        No error bessage, but I have to select it manually.
        Worth to note, that the device manager doesnt detect the card directly as DG but as not identified. After the driver install it shows up as C-Audio.
        Thx for Help

        I’ve Acutally found the cause for this!
        Quite a few people have/had the same problem, maybe it’s worth including in the FAQ 😉
        It is caused by an EEPROM Overwrite.
        You can detect it with the Hardware ID in the Device Manager.
        More info here:
        After booting from dos, and fixing this, the driver also recognised the card as DG and it works now!

        Very strange Issue,
        thank you for your awesome drivers and hard work!


        • CarvedInside    20 Aug 2016 @ 18:33   

          I’m glad that you found the problem. That’s what I would have suggested. I’ve build a card detection system in UNi Xonar v1.80 that prompts the user if card is not detected because of a EEPROM overwrite. Since your card EEPROM changed to one of another C-Media card that system did not kick in.
          Will look into adding a entry in the FAQ for cases such as yours. Thanks.

    i received my xonar dsx today and installed it on my gigabyte z170x gaming 7 mobo and on the anniversary build of win10. i still have sound distortion (crackling, sound going in and out, distortions, etc) after installing the drivers from the main asus webpage and the 1.80 r3, 1.75 r2, and 1.64 drivers found here. also the sounds only affect games, movies, chrome (youtube and etc) but when i use the “test” function in sound devices or just testing it in my drivers, there is no sound issue. the sound issues persist at random times which is hard to pinpoint the problem for me. this is after a fresh reformatting of windows 10 and using both onboard creative recon3di chipset and now the asus xonar dsx. i have tried pretty much everything. enhancements off, un/re-install drivers and using different ones, tested with different earbuds and headsets, disable/enabled devices, etc… i have had this problem for a week now and my last resort was essentially buying the xonar dsx and hoping it will solve the issue. now i have pretty much run out of options at this point in regards to win10. anybody here have any suggestions/solutions for this fix? it seems like win10 is notorious for having terrible sound issues with drivers (realtek and creative as far as i know). thanks for any recommendations.

    • CarvedInside    20 Aug 2016 @ 18:50   

      Are these distortion issues related to the Windows 10 Anniversary build update or with Windows 10 in general? If you started having these only after the Anniversary build 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. Install it without a internet connection present and once installed disable Windows Update service from Control Panel->Administrative Tools->Services.


      • Josh    21 Aug 2016 @ 01:28   

        i had these issues before the anniversary build. however whereas before to fix it, all I needed to do was reboot, disable/enable drivers, uninstall/reinstall drivers, turn off enhancements, etc. the other thing was that before when i would “test” the audio issue in the playback devices, i could hear a weird whirring noise instead of a pinging noise. im going to rollback later today and hope that the earlier build will just be like before but like i stated earlier, these issues were evident before. now its just become consistently worse and at random times for whatever i do.


        • Josh    21 Aug 2016 @ 06:39   

          just to give an update. i rolled back to the 1511 windows (pre anniverary build) and installed the 1.75 r2 uni drivers for my sound and im still having issues. at this point i have no clue what exactly is causing my sound issues. i may just forgo win10 and go to win7 or win8.1 since 10 is causing audio issues for me.


          • CarvedInside    21 Aug 2016 @ 14:57   

            You should look into updating motherboard BIOS if possible. The problem could come from the motherboard PCIe management. Also try the audio card in another PCIe .


            • Josh    22 Aug 2016 @ 00:25   

              my bios is updated to the newest possible that isnt a beta and i have swapped between pcie slots and its still an issue. it affected both onboard and the external sound card as well so i doubt its the mobo.


              • Josh    22 Aug 2016 @ 08:27   

                so i found out that i have been getting high dcp latency using latencymon and figured out that the directx kernel and possibly wlan drivers might be causing audio issues. this seems to be a issue for many and especially those on win10. i originally found a thread and this guy has near identical issues that i have but with different hardware. i still havent been able to figure out the solution yet but for future reference, i at least identified the problem.



                • CarvedInside    22 Aug 2016 @ 14:00   

                  Just a heads up, LatencyMon isn’t always correct about the DPC latency, may say that a system has high DPC latency and has problems playing audio/video when in fact it does not.
                  For fixing high DPC Latency I suggest you follow the 4.Tips & tweaks in reducing DPC latency. Since your motherboard has 2 LAN card, disable the one that’s unused. If you are still using the Xonar card, install the drivers with “Low DPC Latency” or “C-Media Panel” configuration and do not use ASUS Audio Center to control the card. Hope this helps.


                  • Josh    23 Aug 2016 @ 03:45   

                    i have installed both low dpc latency and c-media panel and neither worked. i downloaded dps latency checker and it tells me that the absolute maximum is 1496 and i never had any red bars, mostly yellow 99% of the time. apparently the software tells me that i shouldn’t expect any audio issues just like latencymon which is weird. i am still currently using the asus xonar card and swapping between that and my onboard for testing purposes. i have disabled my “killer” lan port and only enabled the default intel one. i disabled HPET in my bios and that also didn’t solve the issue. I think i will consider installing w7 and/or getting a dac/amp combo to usb and trying that out. hopefully if the dac/amp combo works then my audio issues might be fixed? anyway thanks for the help so far. it seems like any troubleshooting i try ends up not working.

    Hi, I’m interested in buying a Xonar card to lower cpu load even more. Can anyone tell me if the basic drivers have the option for Loudness equalization? like here :



    • CarvedInside    21 Aug 2016 @ 14:48   

      Hi. From what I understand, Loudness equalization normalizes the sound so quiet sounds are easier to hear and loud sounds are less loud. Xonar drivers do not have a that exact option but have something similar, it’s called SVN (Smart Volume Normalization). SVN may or may not work like “Loudness equalization”.
      Xonar cards do use the CPU just like onboard cards or even more. Besides that, I would not recommend buying any card that’s sold by ASUS or are powered by CMI 8788 audio chip as they have some issues that aren’t solved and you might run into them.


      • Charles    21 Aug 2016 @ 16:57   

        Hmmm.. I see. Are there any sound cards you would recommend that has good drivers, or microsoft drivers (included with the OS) that would offload the CPU?

        thanks again!


        • CarvedInside    21 Aug 2016 @ 20:56   

          I don’t have a recommendation. People go for external cards for improved sound quality. My advice would be to look into buying a more powerful CPU.


  11. Robby Robertson    21 Aug 2016 @ 11:17   

    Hi Everyone!
    I have a problem long time ago ( 3 years ), when i’m listening music, YT, or Windows media Player, VLC, etc, and when i stops / pause the music, or video, i get crackling sound but it’s not always.
    I was tried everything, bought new Motherboard, bought APC PM5-gr surge protector, check all PSU cable, new drivers, old drivers, on-off function, No HDD No ODD No VGA card only the sound card, and SSD, but nothing helped. I tried Win10, but the problem was worse. It is very annoying, and I’m desperate to nothing helped.
    I launched DPC Latency checker and the values are good. 50-150 all green.

    Specs: i7 3770K, 16Gb ram Corsair DDR3 1600, HDD WD 1TB Black, SSD A-Data 240 SX930, Mobo MSI Z77-A G43 ( new bios ) OS: Win 7 Ultimate, VGA MSI GTX 970, Asus Xonar DX.

    Best Regards: Robert
    Thanks for the help!


    • CarvedInside    21 Aug 2016 @ 20:53   

      Do you have this issue when using the onboard audio card?


      • Robby Robertson    21 Aug 2016 @ 22:21   

        I have same problem yes, with Onboard audio.
        I checked now my psu, how he can Voltage good 3V, 5V, 12V etc, and anything looks good. My PSU Corsair AX760 very good quality.


  12. Rene Manzano G.    21 Aug 2016 @ 22:26   

    Hi Sir.
    Thank you for sharing your drivers.
    I am testing UniXonar on a Xonar DG card, and realized that latency improves form 10 to 1 ms, Also better sound quality.
    Which driver you recomend for Xonar DGX?


  13. rBose    22 Aug 2016 @ 15:16   

    Updated to anniversary successfully and everything is working fine on my end after 2 weeks of testing.

    Asus Xonar D2/PM 192KHz, 5.1


  14. PipPop    24 Aug 2016 @ 14:56   

    I’m currently getting issues with the center channel being muted if I set the card to 5.1 sound in mpc-hc with a 5.1 surround source audio. Anyone else have this issue or any clue on solving it?


  15. George    24 Aug 2016 @ 16:25   

    Xonar DG, clean Anniversary install, no problems installing the recommended 1822 v1.75a r2 driver.

    (btw the “Page updates/changelog” links at the top -the ones with the bullets and dates- don’t seem to work)
