RELEASE NOTES

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 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 (2.0.0.14), 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:

  • 1.75a “Standard”

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

Other notes:

  • These drivers will work with the previously supported Xonar cards on Win Vista/7/8.1/10 but may require that you enable Windows Test Mode on 64 bit OS.
  • These drivers do not work for the other Xonar cards on Windows XP.

Known issues:

  • ASIO in 64 bit mode does not work. The cause of this issue is the 64 bit asio  dll file from the original STXII drivers.

Notes about Windows 10 compatibility (updated 06 Feb 2018)

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.

Windows 10 Fall Creators Update (version 1709) reported issues so far are (updated 06 Feb 2018):

  • Drivers above 1821 v1.71 may cause BSOD when waking system from sleep (#1, #2, #3). It’s unclear if it is a driver issue or a Windows issue that’s triggered in specific conditions that are met when using drivers above 1821 v1.71. Since ASUS/C-media driver support is pretty much dead and most people didn’t have this issue until Windows 10 Fall Creators Update, people having this issue should contact Microsoft support and submit their crash dumps. (20 Dec 2017)
  • Card settings are being restored after each restart. A temporarily workaround would be to save your settings as a XonarSwitch profile and apply it each reboot. Anyone affected should report the issue to Microsoft. Update 06 Feb 2018, it looks like this is fixed in insider builds >= 17074, and it will be fixed in Windows 10 version 1803.
  • Default format(bit-depth and sample rate) from Windows Volume->Playback devices and the number of audio channels resets each time the Windows Volume icon is clicked (#1, #2). Anyone affected should report the issue to Microsoft.
  • Possible high frequency tone when playing audio.

Windows 10 Creators Update (version 1703) reported issues so far are (updated 10 May 2017):

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 (version 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.

    My card would work for a moment, and then I load PUBG and bam, it’s soft as hell, and some frequencies are too soft. All sound sounds muffled. But then windows sounds come through loud. But all audio is messed up. (Videos, audio, etc).

    Now doesn’t matter what driver or how many restarts, still screwed. Think it’s time to plug my Essence STX into another PC and see if the card died, or if it’s Win 10 1709.

    FYI Everyone with the sound resetting issue on FCU windows 10. The issue has been fixed with insiders build 1709 build 1704 and on. I have verified it.

      Thank you for the information. I think you meant Window 10 version 1803 insiders build 17040 or 17004. Please clarify the exact build number.
      Btw Until now I made the confusion of calling Windows 10 versions as build numbers.

    Hello, I am thinking to buy second hand xonar d2. Should i make this movement ’cause depending on latest comments on this page, drivers are seems kindy problematic. I am using latest windows 10 version and updates. Let me ask one more question? If i had xonar d2, which version should i have to use?

    Reply

    • CarvedInside30 Jan 2018 @ 18:35

      v1.71.
      Some problems are from the drivers and some problems are from Windows 10 and are happening other cards as well.
      You should know that the Xonar cards are no longer supported by ASUS and audio chip maker C-media. If M$ decides to make some drastic changes to Windows 10 audio, the Xonar cards may end up not working anymore and there won’t be any fix.
      I would advise getting the a D2X or DX instead, because if you upgrade your PC you may not have the PCI slot required by the D2 card.

    I’m grateful that the UNI drivers exist and are still maintained. I’m in a serious bind. I’ve been using a Xonar DGX card for 2 years. It has been detected by Win 10 automatically. Within the last 7 days, I got messages that the DGX was not correctly detected. Running the “Resolve Audio Problems” applet resolved my issues. **I only use the DGX to run 1 optical output to an external DAC and 1 bog-standard mini-jack input microphone. —–On Saturday, being a ‘tidy’ pc conservator, I tried to reinstall the Xonar driver with an Asus update: every card option failed. —-I uninstalled the ASUS driver and installed the UNI most recent Beta: no change (but blue screens). I uninstalled the beta and installed the Stable 1822-1.75ar3: the Xonar card *showed* all was well, and the DAC even showed a signal lock. But I could get no output sound from either of the detected output sources. —–[I then uninstalled and removed the Xonar card and attempted to installl the original and four variants of the Realtek drivers for the mobo integrated audio. Have restarted the machine 50 times in the last three days. Confusion and despair have resulted.]

    –I want to try to reinstall the Xonar DGX card a last time. My experience has been that if it is installed first in Win7/8 and the OS updated to Win10—or if it is installed immediately with a fresh Win10 install—it will function with the ASUS drivers. I appeal for suggestions from you and the community. I have read the Trouble-shooting guides and these responses in the thread. I have run the Xonar driver uninstaller and Driver Fusion to remove any vestiges. Are there any specific recommendations anyone would make for installing the Xonar DGX with Win10x64 (Creator’s Edition) installed (I can’t roll back the update)? I only need optical out and a single crummy mic in to work. Thank you.

      If I understood correctly, you’ve tried the S/PDIF output of your Realtek card and that didn’t work either. If that’s the case then your problem most likely is from the connection or DAC and not the soundcard.

    If ASUS and CMedia does not support xonar cards anymore, why dont they give the driver sourcecode out to help ppl. who want to develop new driver. Could you develop a new driver from start? Maybe it would be better than the buggy official… The xonar STX is still a very good card but without support its almost crap.

      I can’t do that. Making a new driver from start would take huge amounts of work and it will lack proprietary protocols like SPDIF Dolby Live encoding and others.

        The Xonar DSX still kicks ass ! I have also Soundblaster Z and bought DSX intentional for my media PC I tested it in my Omen first and WOOOW!!!! I was surprised how much better the Xonar sounds then SBZ on all levels and fields so I decided to keep it in my gaming rig and bought another one also DSX for my media PC . I will keep SBZ as backup In case Xonar wont be working properly due to lack of driver support in some future time. I also opened a complained ticket by Asus regarding future driver updates .
        I love DTS and everything DTS related and XONAR DSX si the KING in this field .
        Thank you for keeping the Xonar alive !
        P.S: original ASUS drivers from (2015) also working without any problems on the same system , but I prefer this package .

          Let us know if they have something to say about future driver updates. I suspect they will say something like they continue to support the cards.

            Hey DARKO and Carved, let me ask a question from a noob guy =D, using the Z906 via TOS isn’t bypassing all the benefits from DSX?

            Thanks in advance.

              Hi. By using the audio card optical output you are bypassing the card’s DAC and op-amps and use those in the speakers instead. Depending on the quality of the DAC and op-amps in those speakers, the sound might be better or worse than from your sound card. If you want to use the audio card for the sound processing you will need to use the analog connections.

            Im quite shocked by the answer ?? In fact I have no idea what he is saying ??? like there might be only if there is some incompatibility issue or what ??
            “Dear Valued Customer,

            Thank you for contacting ASUS and your feedback as well.
            The card was realesed in 2014 and the updates will be as per the hardware support and bugs which are will be found or reported by customers. ASUS simply cannot update the software when the hard ware too supported. Thank you for understanding.

            Kind regards,

    Hi ! I was wondering if there was any update on Asus website for Asus Xonar DX soundcard and it appears that there is nothing up to date. Trying to know the best configuration for my soundcard when used with a brand new Sennheiser Game One, I went from forums to forums and finally came here because other people mentionned the Uni Drivers !

    What would be the best choice from your drivers library for Windows 10 + Sennheiser Game One + Asus Xonar DX ?

    At the moment, I’m running Asus drivers from 2015 but I find the Dolby and the Virtual Surround a bit clunky (it does like metallic noises…).

    Thank you !

      Hi. It depends on your needs and issues. Maybe you should start with 1.80a since these use the same audio drivers as ASUS latest but with additional fixes. From there go try the others see if there is one that performs better for your needs.
      I suggest you check the FAQ Q&A 9 for suggestions on how to properly configure the audio settings.

        Hi. Thank you for your reply. I think the Virtual Surround for headset is really not for me. I don’t like the way it sound and it is really not the same as a real 7.1 speaker system. My Sennheiser Game One is brand new. Maybe I need a burn in track in order to optimize it ?

        I still didn’t try the UNI drivers. I’m afraid of a BSOD or something that could make my PC crash.

        What do you think ?

          I don’t know if your Sennheiser headphones need a burn in period.
          UNi Xonar drivers won’t crash your system any more than original drivers.

    Latest Windows 10 Fall Creators Update monthly update to latest build February 13, 2018—KB4074588 (OS Build 16299.248) includes an interesting fix: -Addresses issue where surround sound audio endpoints reverted to stereo after restarting.

    I am going to update and test it right now.

    Hi! I just installed win10 today after using win7. My Xonar essence stx (i dont know wich one, but a very old one) stoped working, i tried drivers from Asus and i tried yours but i got nothing. I can see in my sound settings that the “volume” moves when i play an audiofile but i cant hear anything. My headphones works when i use the sound from my motherboard, i tried to disable motherboard audio in bios but nothing helps. Any idea?

      Hi. Is the card detected in Device Manager -> Sound, video (…)? Does it say that “Device is working properly” under “Device status” in ASUS Xonar STX Proprieties?
      Are you using analog(jacks) or S/PDIF output? Are you headphones connected to the front panel or to the rear of the card?
      If you right click Windows Volume and select Playback Devices, is the “Speakers Asus Xonar(..)” set as default device?

        Hi! Working properly. Using Analog and its connected to the rear of the card and Asus Xonar set as default. Maybe the card is broken but thats also abit weird that it would break exactly the same time as i install win10.

          Which Windows 10 version do you have installed?
          To see if your card is the problem, you should install windows 7 on a another partition or check your card in another PC preferably with windows 7 or 8.1 and see if it works.
