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 25 Mar 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 Red Stone 4 Preview builds (17123.1 and later) notes

Our community member Chris Leipold reports that the wake up from sleep BSOD, settings reset and not working audio server process at startup issues that where introduced with Fall Creators Update are now fixed. Furthermore, if you have “Dolby Atmos for Headphone” app you should remove it and replace it with the updated “Dolby Access” app in order to avoid audiosvr process stack overflow errors that are crashing the audio subsystem.

Windows 10 Fall Creators Update (version 1709) reported issues so far are (updated 8 Mar 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.
  • 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 6 Feb 2018: it looks like this is fixed in insider builds >= 17074, and it will be fixed in Windows 10 version 1803. Update 8 Mar 2018: this should be fixed with KB4074588 update for version 1709.
  • 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. Update 8 Mar 2018: this should be fixed with KB4074588 update.
  • 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.

    Windows 10 has a feature called loudness equalisation embedded in the OS (it’s working even without installing realtek drivers). It’s driving me insane, since it randomly silences various applications. Is it possible to bandaid this isuse through UNI drivers?

    Reply

    • CarvedInside25 Mar 2018 @ 22:47

      Are you saying this loudness equalization Windows 10 feature is different from this controllable option or at least it’s that option but it’s always enabled for the Xonar card? It silences various applications completely or it just lowers their volume? Could you explain in detail the issue and how to trigger its effects? You didn’t have this under previous a Windows version? Which Windows 10 version and build number do you have installed?

      If the sound goes out completely, could it be the WASAPI Exclusive Mode feature that does this? You can disable this by unticking “Exclusive mode” checkboxes from “Windows Volume right click -> Playback devices -> Speakers Asus Xonar(..)-> Proprieties->Advanced tab” and see if it solves the problem.
      If it only lowers the volume could it be the volume reducing feature when communications are detected from “Windows Volume right click-> Playback devices -> Communications tab”? Or the Dynamic (fluctuating) volume when there are 2 or more active sound sources?

        In my case there’s no enhancement tab all. So I’m not entirely sure whether it is the same feature you show on the screenshot or is it the same, working in the background by default until one installs realtek drivers for enhancement tab to appear (to turn the feature off). I tried installing realtek drivers to make it appear, but it didn’t work and when asking people on windows-related forums they blame custom drivers for interfering (sounds like nonsense tho)
        I am not sure how to trigger the issue. It appeared while switching between speakers conencted to sound card and USB DAC that I plugged my headphones in. At the beginning I thought my discord broke but turned out that only the volume was reduced.
        It doesnt silence applications completely, just reduces volume to 0. My os version is 1709 and compilation is 16299.192.
        I disabled exclusive mode, not sure if it fixes the issue yet.
        I never activated SVN and the communication tab is just as Chris shown on his screenshot.

      You should set this as well if haven’t https://imgur.com/a/resEY and check if SVN is disabled as well as described in the second link Carved posted.

    Hello, everyone

    Are there any tool like “fpswitch-new-version” that changes between “SPEAKER” and “FP HEADPHONE” by simply clicking the exe? No running process or fuss.

    Maybe author of fpswitch-new-version can add some kind of .ini file support so we can put which output device we’d like to switch between.

    XonarSwitch seems kinda buggy. Headphone AMP always automatically reverting to VOIP mode and Recording Mixer’s L R’s selection are always on “more right than center” (clicking reset defaults it to center, but it always reverts back)

    I really like low DPC/latency mode of Xonar Uni Driver. I love how it sounds and i don’t need to use any feature on the ASUS control panel. My speaker (rear) and headphone (FP) is always connected. So i’d love to switch between these two without running ASUS/CMedia/etc control panels.

    I do believe what i am trying to do is pretty common, i hope someone already modified fpswitch-new-version and maybe willing to share?

    I really wanted to try this driver on my new stxii but can’t get my system into “test mode”. It’s being blocked by something called “secure boot” which I can’t find a way to disable. Being as I’ve disabled the onboard sound I’ll have to use the Asus driver.

      “Secure boot” option should be in BIOS/UEFI. Before disabling that you could try the Disable Driver Signature Enforcement method and see if it works. Let me know if it worked.
      If all else fails, you could install the “b” version of the drivers because they do not require test mode for your card.

        Thanks for the reply Carvedinside. I tried three times to use the “Disable driver Signature Enforcement” method but each time it did not give me opportunity to press 7 or F7 to select it so it just booted into windows normally, so I gave up on that path and installed the “b” version as you suggested and it did indeed work 🙂 so I’ll stick with that version.

        It has not however fixed my problem of the STX2 not picking up the mic on my new Beyer MMX300 Gen2 gaming headset. With your driver it will detect and work with my “Modmic 5” which it didn’t before. With the MMX300’s it pops if I click any of the buttons on the inline remote or touch the plug on the detachable headphone end but no sound on any port even on PC through the mic, even with the mic boost on. Oddly the gen 2 headset also comes with a shorter lead meant for connecting to mobile devices and this only has a single combined termination instead of splitting into 2 (mic and headset) and if I connect that combined plug into the mic port on my front panel the mic on the MMX300’s works! But this of course leaves the headphones not working. I’ve spent literally 12 hours on this playing with all the sound settings, defaults etc. so I’m going to give up for now and maybe try a USB DAC just for the gaming headset and leave the STX2 just for listening to music through my Sennheisers which do sound much better through the new card.
        Sorry for the epic post but I wondered if anyone else had tried the combination of the ST2 and the MMX300 gen2.
        Thank you for you efforts 🙂

          OMFG! After all that buggering about I finally came across a post about people sending back their Beyer’s because of the mic issue.
          The resolution?
          Wrap a tea towel around the plug to the headphone cup and push as hard as you can with a pair of pliers until it clicks and I’m a steel fabricator who can pull a beer bottle top off with my bare hands. You really have to push that hard!
          So fixed! 🙂
          All I need to figure out now is why the audio channel selector is stuck on 6 channels :/ Sounds awesome though.

    Is it necessary to buy/install Dolby Atmos to get Dolby Headphone to work in Windows 10, or is the setting in the c-media panel enough?

    Beware, on Win 10 Pro x64 17133.1 RS4 mic does NOT work with this version.. in my game Team Fortress 2, and everything else, mic does not work, the game doesnt even register me pressing my button to talk. OS itself doesnt even show the volume meter rising when i tap the mic, yet when clicking listen to mic feature it does play it back, ruling out a hardware failure. We got 2 different systems in this house with the same Asus Xonar DGX sound cards in both, both failed at the same time in the same way upon updating to Windows 10 Spring Creators Update…

    I did everything possible already, reinstall, run as admin, DDU, bla bla, offical drivers, trying older Uni Xonar drivers, disable driver sig enforcement etc, NOTHING works. Mic is dead. Is this purely Microsoft’s fault or can a newer driver work around this?

      This looks like a Windows 10 RS4 bug. To get better picture of what is happening you should try the following:
      With the Xonar card are you using the front panel microphone connection? If you do, try connecting it to the rear of the card and disable Front panel mic in Asus/Cmedia Panel.
      Check if the microphone works with the onboard audio card. If this would work, you can still use the Xonar card for playback.

        Dont use front panel and its off already, as having that on stops it from working before. Onboard realtek mic dont work either, on my laptop with realtek as well, its integrated mic also stopped working.

          Thank you for the followup information. You should report the issue with the details to Microsoft Windows support.

      For me, it’s working properly with a D2X, DG, and a DGX as well with Realtek sound. Could only advice a reinstall but if you did this already my last idea is that your Mic might be broken. Can you check this on an independent, not RS4 device? BTW which driver version?

    When i use a microphone on my ASUS Xonar DGX + Unified Drivers, the mic’s sound can only be heard in the left ear. I don’t have that problem on the stock ASUS drivers.

      Where have you noticed that? Are you using Microphone Monitor option? How about if you are recording the sound?
      Which OS version and build number do you have? Which UNi Xonar drivers have you tried? Which version were the original drivers? Microphone is connected to the front panel or directly to the card?

      With the system in the current state I suggest you check again with original drivers, then check with several versions of UNi Xonar drivers and report back.

    I am on win10 1709. I wonder which one of the drivers is the most stable for me?
