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.

Notes about Windows 10 compatibility (updated 13 May 2018)

UNi Xonar drivers v1.64 and above will work with 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 (multiple versions) possible issues and fixes:
  • Microphone not working – Check this guide. (thanks Shane)
  • Audio crashes – If you have “Dolby Atmos for Headphone” app installed 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. (thanks Chris Leipold)
  • Popping and cracking sounds – If you have a AMD graphics card, try disabling AMD High Definition Audio Device from Device Manager. Possible to try the same steps for Nvidia HD Audio Device for Nvidia cards. (thanks Marc)
  • BSOD’s after system wakeup from sleep – Try UNi Xonar v1.71.1 driver. (thanks Kalle)
Windows 10 version 1803 (April 2018 Update) notes (updated 13 May 2018)

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 fixed with Red Stone 4 preview (pre 1803 release).

Possible issues and fixes:

  • Microphone not working – Check this guide. (thanks Shane)
  • Audio crashes – If you have “Dolby Atmos for Headphone” app installed 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. (thanks Chris Leipold)

Possible issues reported so far:

  • Settings (Bit-depth, sample rate, number of channels) reset bug when clicking the volume after restart might still happen (#1)
  • Windows might freeze when installing Xonar drivers (#1)
  • Microphone might not work even after doing the microsoft privacy toggle fix (#1)
  • S/DPIF output might not work at least for some with Xonar DG cards (#1)
Windows 10 version 1709 (Fall Creators Update) notes (updated 13 May 2018)

Reported issues so far:

  • 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. Update 13 May 2018: This issue might still happen even after installing KB4074588 (#1).
  • Possible high frequency tone when playing audio.
Windows 10 version 1703 (Creators Update) notes (updated 10 May 2017)

Reported issues so far:

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.

    I don’t know if this is anything anyone can do anything about to fix but regardless of if I use stock or modded drivers I get exremely high audio latency problems when running the Metro Redux benchmark if I have 24bit 192Hz selected. Switching to 24bit 48Hz fixes the problem. I’ve verified this is a driver bug with the Xonar drivers by switching to the onboard ALC1220 and using 32bit 192Hz format. I’ve also tried swapping the PCI-E slot my Xonar uses without any success as well.

      I don’t know what can be done about this. For the record, tell us your card, complete OS version and drivers that you’ve tried.
      I’m not sure if you know, but setting 24bit 192kHz would only be beneficial if you have the audio files in 192kHz.

        Hi CarvedInside,

        The card I have is the Xonar DX 7.1 PCI-E, I’ve tried every stock and modded driver I can find on the net right up to the newest 1825 branch. As useless as I knew it would be I even contacted Asus support and.. you know how this sentence is going to end, they were bloody useless and didn’t even know there is an 1825 driver. This problem has also persisted over every version of Win10 I have used (not tested with build 1803 yet just got it installed) I’m a modder so when I work with audio files I do make them very high quality which is why I use 24bit 192Hz. Having to switch back to 24bit 48Hz all the time for everything else is just wearing a bit thin now so I thought I’d drop a message here hoping someone knew something about this problem. I have also in addition to swapping the PCI-E slot the Xonar is in tried all available control panel varients including the one for low latency without success. I really wish Asus would take their thumb out of their backside.. their still infinitely better than Creative but thats not really saying much a blindfolded one handed chimp writing drivers would be infinitely better than Creative.

        The only two things I found recently that might bare fruit is a blog by daniel_k who has modded Xonar drivers, and some drivers that were being rewritten from Clemens Ladisch together with these guys you might be able to come up with something for the Xonar cards. Heres the links; http://danielkawakami.blogspot.co.uk/2017/01/updated-windows-10-drivers-for-asus.html https://www.phoronix.com/scan.php?page=article&item=939&num=1

          Just to be clear, when you say high audio latency, you are referring to a delay in sound output, right?
          While it’s a long shot you could try the SpeakerCompensation tweak.

          Starting some new drivers from scratch for the Xonar cards won’t be possible.

            Hi Carved,

            When I say high audio latency I mean (with Metro Redux at least) that when the audio is playing sound effects cause very inconsistent framerate combined with some sound effects being caught in a delayed or high latency loop. Sometimes the loop is only brief, other times lasting for several seconds. I’ve been able to test with the new 1803 W10 x64 build and can say the audio delays in the benchmark are worse than ever, even switching down to 16bit 48Hz does nothing to remedy the issue now so I’m going to have to do some more investigating. Like older W10 builds switching to the Realtek ALC1220 resolves the problem completely. From the behaviour I’m seeing the root of the problem appears to be coming from the latency introduced by the PLX chip on the Xonar as its adding to the PCI-E latency already inherent of the motherboard, which as far as I am aware is 64 clock cycles. I have some graphs from the benchmark comparing the Xonar at 24bit 192, 24bit 48, and the Realtek 1220 at 32bit 192 giving a good visual representation of how these audio loops / delays with the Xonar affect the game if you would like to see them.

          Do these 1825 drivers work better than the official Asus (1823)?
          I have a Xonar dx sound card, I would like an even better sound if possible.

    Question to other xonar users who have or have had the common microphone hiss/whine on boost, how did you fix it?

    I have a very interesting problem.

    Ok, so my card is the Xonar DG and I have a headset.

    When I plug my headset mic into the back panel Mic in/Line in port it doesn’t work.
    When I plug my headset mic into the front panel Mic in/Line in port it works.
    When I plug my tablet into the back panel Mic in/Line in port it works.

    So it appears that the back panel port is working, as is the headset microphone, yet the mic doesn’t work in the port.
    I have tried a different headset as well, yet the same problems remain.
    Stranger still is the fact that it all worked fine until I plugged the tablet into the back Mic in/Line in port.

      Try uninstalling the drivers and installing them again.
      If it does not work, might be a problem with the cards “Mic in” jack somehow no longer making proper connection with the microphone jack connector and maybe the tablet cable still works because it’s slightly different.

    I am told on the guru3d forum that PCIe to PCI adapters that have an Asmedia 1083 chipset-revision 3 will work with the Asus Xonar ST, but have not yet tried this………most of those adapter cards seem to be $40-60, so I don’t know if I want to pay 1/3 of the price of a new soundcard for an adapter that may or may not work for me. I saw some posts about the Star Tech adapter (which does not work) but has anyone tried one of these?

    Regardless of the functionality of the adapter, my next thought would be clearance. The Xonar Essence ST output jacks and case alignment are going to be about 1/2 inch off, as the adapter’s bracket is the one that is secured to the case, not the actual sound card…..meaning that the output RCAs will either come in contact with the case, OR, the gold mounting bracket has to be removed (leaving a fairly heavy card to just hang off of the adapter), not to mention the cable clearance issues. Unfortunately, I think that these PCI cards are pretty much obsolete.

    Help me pls. I can’t install drivers UNI or official. I have BSOD. Windows 10 with last update. I can try install versions from 1.81 to 1.64.

      Which audio card do you have? Which drivers have you tried? Have you tried 1.71.1? Try them and the other versions maybe one will work.
      Also try installing the audio driver only(Possible solution 1) and report if that works.

          Yeah most likely some issue from the Windows 10 1803 version. Still, you could try multiple UNi Xonar drivers, one of them might not trigger the issue. This was the case for others in the past.
          If none work your only option is to roll back to the previous Windows 10 version.

    Hello, I just discovered your site that just help me configure my sound card, Xonar DGX. When I wanted to make the settings of the sound (windows 10) the software crashed. With your software I no longer have this problem. The only thing I can not configure, these are the system input channels, as soon as I choose 2ch or 8 ch the inscriptions disappear. If you have an idea, I’m interested. Thank you for your site and good luck. Yours, Christian

      Which version of Windows 10 do you have? Where are you changing the number of channels? Which drivers have you installed? Maybe you can upload a screenshot with the problem.
      If you are using Asus Audio Center then you should check C-Media Panel that’s already installed with UNi Xonar drivers or check XonarSwitch.

        Hello, I’m coming back for a good news or a miracle (…) since the last update of windows 10 insider, the C-media panel is working properly. I can choose the number of channels, speakers finally it is operational. Thank you for your help and advice who are always welcome. Feel free to improve the program, the years go by if you put your finger on it, it will last a long time. Thank you and have a nice weekend, Christian

      Are you referring to Stream What You Hear application?
      I don’t think it’s a Xonar driver problem. Please check with the onboard audio and see if it works with it.

    Hello,
    I’m using a Asus Xonar DGX soundcard and have some issues with my mic. Everything worked fine for me (since I got the card) until two weeks ago….
    My problem is that my mic is not working anymore. I have already checked everything but can’t find the problem. When I tick the option “monitoring” in the microphone options I can hear myself. So there must be a software problem. I also deselected the option “front mic” and activated the mic in my privacy settings….Does anyone have the same problem and knows how to fix this? Headphones are working fine..

    Thank you in advance!

      Hello. Try the connecting the microphone to the onboard card and see if exhibits the same behavior.
      You should also reinstall the UNi Xonar driver.

    Hey, I can’t seem to see the download link or are they only downloadable under the standalone packs?

    Reply

    • CarvedInside12 Jun 2018 @ 13:57

      They should be under driver downloads and above standalone packs. The driver download entries load separately as an iframe so maybe for some reason that’s blocked on your browser, probably by an extension you have installed. If they do not show up please tell me which browser are you using and if you figure which extension blocks them.
      If you are still having trouble seeing the download links you could check with a different browser.

    Hi there,

    I seem to recall a version of the driver and the DG Audio Center UI having buttons for music and gaming, including the usual DSP mode – I’ve since reinstalled Windows and thus these drivers and those buttons have gone. I’ve tried two previous drivers too, perhaps I am not going far back enough? Any ideas anyone? Thank you in advance.

    Hello,
    First I wanted to thank you for your drivers and the excellent support you provide for them. Right now I am having an issue that may not be related to your drivers, but I am not able to figure out what is wrong on my own.

    The issue is that my microphone is listed as “currently unavailable” in the sound control panel. This problem has been happening for a few days. It was originally intermittent, and fiddling with the bitrate of the microphone seemed to have some affect on causing it to work again. The issue is now constant unfortunately, and my microphone is always listed as “currently unavailable.”

    To try to resolve this I have tried your past two drivers, tried two sound cards (I have two eclaros due to a mistake a long time ago), tried two microphones, and tried two PCIe slots. My privacy settings seem to be in order.

    Before running into this issue I did a couple things that could have affected it. I moved my sound card to a different slot without uninstalling it (while powered down, and I did have to reinstall the drivers afterwards of course) while trying to hunt down the cause of a phantom noise. I also have been playing a game that causes me to swap my playback bitrate, so I have been swapping bitrates frequently.

    When I uninstall the drivers now to reinstall them (in an attempt to fix the issue) I am doing so from the device manager.

    Any thoughts you have on the issue would be appreciated, thank you!

    Update:
    A followup to what I just wrote:
    I was being (really) dumb, I didn’t see the c media drivers in my control panel so I had been uninstalling through device manager.
    I forgot there was a “UNi” in front of them. I uninstalled them correctly this time and everything is fine. My mic is back to working.

      A further and unfortunate update to my issue:

      Today upon restarting my computer the issue was back. I restarted a few times while leaving mic monitoring on and it was alright. I noticed that when I restarted without monitoring on that sometimes the “Line In” option would become available and the mic would again go unavailable. I disabled the line in and after 10 restarts the mic has been working each time (without the line monitoring).

      I really botched something up, but at least it is working right now.

      • CarvedInside18 Jun 2018 @ 04:11

        Line In and Microphone inputs cancel one another depending on which is in use. The problem probably comes from a program you use which uses the “Line In” input. This could even be a webpage in a browser.
        You should check that Microphone is set as default under Windows Sound -> Recording when “Line In” is enabled.
