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”

Driver for previously supported cards. Same audio drivers as those in 1.72 (1816 for Win XP, 1822 for Windows Vista/7/8/8.1/10).

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 18 Nov 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 5 Oct 2017, 18 Nov 2017: Windows 10 Fall Creators Update (build 1709) reported issues so far are:

  • 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.
  • 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.

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.

    Getting high DPC latency / stuttering in games with “UNi-Xonar-W10-1825-v1.81a-r2”.
    Highest reported DPC routing execution time ( 2000+ µs): ( cmudaxp.sys – C-Media Audio WDM Driver, C-Media Inc)
    Using latest Win10 ( 1709 ) and Xonar DX, installed using Low DPC latency as well.

      Try installing some of the previous drivers. If you still have this high DPC latency I think it may be a newly introduced issue with Windows 10 build 1709.

    HI. I just want to remove the uni xonar drivers entirely from my computer and then reinstall the basic asus xonar drivers. I understand that your drivers are superior, but I want to go back for my own reasons. However, when I uninstall the uni program from my computer (windows 10), and then install the xonar drivers from the asus site, the program still seems to be using the uni drivers. How do I go about removing the uni drivers from my computer entirely, so I can do a fresh install of the basic asus drivers? Thank you so much for all that you do!!

    Hi,
    I’m currently using Xonar DGX with UNi v.1.80a r3 drivers. I have Windows 7 but I’m building a new PC soon and probably upgrading to a Windows 10. From what I’ve read around the forum, Windows 10 compatibility is problematic. I listen to a lot of music, play some games and watch movies. I have Philips Fidelio X2 headphones. Just wondering which drivers would be the best bet for Win 10 and Xonar DGX? I’ve had no issues in Win 7 with UNi but didn’t work at all with the Asus factory drivers. Is the DGX okay for Win 10 or should I go for something else?

    • CarvedInside24 Nov 2017 @ 01:36

      Hi. I personally suggest you avoid the Windows 10 mess and try to install Windows 7 on your new PC. You may be required to slipstream some drivers to your Windows 7 install DVD/USB. If you decide to go with Windows 10, I don’t know maybe start with v1.71 drivers.

    With my HT Omega eClaro, UNi Xonar 1816/1821 v1.71 is the only driver that doesn’t give me Windows 10 BSODs during or after sleep. I’ve tried everything else including the most recent Xonar drivers as well as HT Omega’s 1825 drivers. All lead to BSODs except 1816/1821 v1.71 drivers. Am I losing any real features or benefits from using almost 5 year old drivers? Are there enhancements and features in the 1825 drivers that outweigh the BSOD issues?

      I don’t think you are missing anything in terms of features. Each driver has different issues I’ve noted some of them in the release notes, choose the one that works best for you, in this case clearly go with the drivers that do not give you BSOD.

        Thank you. I did a fresh install with the HT Omega’s 1825 drivers attempting to change different settings in BIOS and Sleep power state for the PCI – trying to remove all power loss during the sleep phase – with no luck. I can practically reproduce the BSOD on demand. Forcing a sleep and waking the PC up within a few seconds won’t do it. It needs to sleep for at least, I think, 20 minutes? I’m still attempting to find a “settings” workaround, but i’m close to just going back to v1.71 drivers since it’s the only one that works. Do you know if its maybe a specific tweak you did to 1.71 that makes it work? Or it’s just whatever C-Media did in that version?

          Thanks for sharing the details of the issue.
          I think the issue is because of the changes C-Media did to the audio drivers after 1821 version. Curious enough most of the people don’t have this BSOD issues with newer drivers. It might be tide to other drivers or other system hardware.

            No problem, and what you said is interesting.. I was actually going to ask if you had any insight since you’ve collectively seen all the issues. Have you noticed anyone with Z270 chipset motherboards complaining of BSODs? My current board is Z97 based. I don’t want to force a system upgrade if I’m going to have the same issue again. 3-4 times out of 5 I can put the PC sleep and when I return it already experienced a BSOD and restarted, or, right as I wake the PC it BSODs. The other 1-2 times out of 5 it doesn’t. I can’t figure out why. All the same apps are running in the background in every scenario. Right now it didn’t BSOD and the only thing I noticed different was YouTube wasn’t open in a Chrome tab. However, I’m 99% sure I’ve closed everything in the past (including Chrome) and it still had a BSOD. I’ll have to test more.

              The others that reported BSODs didn’t specified their motherboard. When I said that most people didn’t have these BSODs after wake-up issues, that was based on reports prior to Windows 10 build 1709. With the new reports on build 1709 it seems that many more are affected.
              The issue might be related memory read or write that’s been done by the Xonar driver after sleep resume. But the problem could because of a Windows 10 bug and not a driver bug.

              Your Windows 10 is build 1709?

                Ah ok. Would choice of ram be an issue? Or its still an issue completely on the card/drivers you think? Yes, I’m on Windows 10 Pro 1709 16299.64. I had the BSODs in earlier versions of Windows 10. I’ve had the BSOD issues for every build of Windows this year as well as part of 2016.

                  By memory read or write I was referring to memory operations that are managed by the OS.
                  But of course problematic RAM or RAM and motherboard compatibility issues can give BSODs. Just to be sure you could this with something like memtest86, Windows memory test or Prime95 overnight.
                  Another thing to do is check that you have the latest BIOS installed for your motherboard.

                    Ah got it. I actually went through memtest86 without issue with my ram. Also, my motherboard has the latest bios – which I believe is from 10/2015. I guess it simply boils down to hardware used.. however it’s interesting how the vast majority of users all claim 1.71 has no BSODs. If 1821 seems to be the most solid, I wonder what changed so dramatically in future versions?

    Can anyone verify that Dolby Headphone works correctly on Windows 10 with the latest Creator’s Update?

        You don’t have the dolby headphone audio balance issue you used to have?

        • Case02 Dec 2017 @ 23:03

          OK, maybe saying I don’t have “any problems” was not technically correct. I do actually still have the issue where in Raceroom Racing Experience, my in-game audio is much louder than my menu audio if I’m using anything else than stereo in the game options. So yeah, that’s one issue I still have and I’m not sure if it’s something on my side or some rare in-game bug. Nobody seems to be having this problem with the game except me, though.
          And as for the other games having slightly different audio balance…well, I either got used to that or it’s gone. I can’t hear that anymore.

          One thing worth mentioning is that I’m actually using older drivers, not the latest ones. 1.64 if I remember correctly. The reason for this is mostly because it seems to me like they do have better directionality for Dolby Headphone. Maybe it’s placebo, but I do seem to be able to hear a difference if I test them back to back with newer drivers.

    I was using 1825 v1.81a r2 without issue until the 1709 update. Now there will always be a BSOD after waking up from sleep. Crash dump files indicate the culprit be cmudaxp.exe, I am rolling back to 1.71 as suggested by others to see if that solves the issue.

      Let us know if v1.71 works fine or not.

      • Frank30 Nov 2017 @ 18:24

        Turns out that move sets me on a longer journey… After removing v1.81a I found myself unable to install any versions of driver, for earlier version (1.64, 1.71) it’s “Please plug-in audio device”, and for older (1.80, 1.81) it’s “installation failed”. Have tried everything from safe mode to disable signature enforcement to verifying EEPROM, even did a keep files and apps Win 10 refresh, but was slapped with another cmudaxp BSOD in the end. Probably will try a fresh Win 10 install later today.

            Yes, get a generic “Windows encountered a problem installing your driver” error.

            Before I reinstall Win 10 a new update came out (KB4051963), after which all my troubles went away (I am also having difficulties with display driver after uninstalling sound driver). Not sure why though, my guess is the problems have something to do with the Windows update mechanism.

              Which Xonar drivers did you end up installing after applying KB4051963 update? Do you still get the BSOD after waking up from sleep issue?

                1.71, so far have about 4 sleep / wake and no BSOD. One thing though, after installing the driver waking up take considerably longer time, screen will be unresponsive for a short while, same with 1.81a except that leads to BSOD usually. This is not the case pre-1709.

    Hi,
    I have a Xonar Essence STX II and I’m running Windows 10 Enterprise version 1703. I postponed the update to 1709 until today, hoping that it could go smoothly.
    It didn’t…. After installing the update and restarting, I got BSOD and “system thread exception not handled” and nothing else.
    Windows restored its previous version, so I can use my computer.
    Did anybody else have this error?
    Thank you.

    Just chiming in to say that v1.71 worked for my on Windows 10. I was using the official Asus 1823 version before and was getting BSODs on waking.

    After installing Win10 1709, at first I was logged in with my Microsoft account ([email protected]) before I later switched to local account (“Benny”). I think I installed the Uni Xonar drivers before that change, but I am not sure.
    Sadly MS left me with a user folder named “benja” instead of “Benny”, so I renamed my user profile folder to “Benny” and changed the profile path in the registry.
    Problem is, that Uni Xonar (no matter how I uninstall/clean and reinstall) creates that old/wrong path c:\users\benja\Asus\Xonar….. where there is just one DLL file and the ini file with my Settings.
    I can’t find any registry key or ini file that tells Uni Xonar software to create that path. Maybe it has something to do with the Software installing/running with that UAC-virtualization flag in Taskmanager?
    Is there a workaround for that? I just want those folders/config files in my normal user profile path.

    • CarvedInside04 Dec 2017 @ 14:18

      Isn’t the path “C:\Users\benja\AppData\Roaming\ASUS\Xonar (..) Audio Center”?
      The path with Xonar Audio Center in the name is the path for settings from the ASUS Audio Center and is automatically generated by the AsusAudioCenter.exe using system variables. There is not setting to change that from the AsusAudioCenter perspective.
      Your problem seems to be with the profile path change which didn’t changed all user profile variables. You may want to try something like reversing the benja->benny changes and use User Profile Wizard or some other tool to move the profile to another name.

      • Benjamin04 Dec 2017 @ 14:51

        Thanks for the tip. Yes you’re right, the path goes down into appdata\roaming\ASUS etc. I’m not on my computer right now, so I forgot about the appdata subfolders.
        If it’s a system variable that the Audiocenter is using, I might find out, how to change that variable .

    I must be tone deaf because I don’t hear any differences between the UNI drivers and the asus drivers. I’ve tried many times but I always go back to asus driver. Certainly that being 64 years old makes for less than perfect hearing but If someone here could describe why they like these drivers more than the original, please do so. Also, I never had any problems of any kind with the asus driver.. what problems am I supposed to have …or what make you guys change for the unified drivers? there must be something since so many people are using the UNI driver which work very well also….

      Its not a major change but asus has not spend much time on their drivers in a long time so for some people this driver may fix a major bug preventing them from even running the soundcard in the right setting. There are only a few changes really related directly to audio, but especially for games and such where perfomance can cause skips and such these drivers can be installed in low latency mode and behave much better performance wise than the stock asus drivers, which may or may not improve the audio and/or performance of the rest of the system.
