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.
  • Windows 10: Before updating to new version, you should uninstall the v1.81a drivers, as the update process might result in BSOD (#1).

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.
  • When waking system from sleep, volume from one of the speakers could be x2 louder. Original report.

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:

  • STX II: 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 mainly 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 29 May 2020)

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. You will have the same issues with corresponding versions of ASUS drivers.

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. Here are some solutions on how to prevent a forceful Windows 10 standard or version update.

Some of these issues also apply to other audio cards (Realtek, Creative, EVGA Nu Audio, ASUS Strix etc.) and external DACs.

> Find out which Windows version you have installed.

Windows 10 (multiple versions) notes

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->"Sound, video and game controllers". It's possible to try the same steps for Nvidia HD Audio Device if you have a Nvidia card. (thanks Marc)
  • BSOD's after system wakeup from sleep - Try UNi Xonar v1.71.1 driver. (thanks Kalle)
  • For systems with 1.81a drivers, the upgrading process to new Windows 10 version might result in BSOD (#1) causing the installation to fail. To avoid this problem, uninstall the v1.81a driver before upgrading.
  • The number of audio channels resets itself back to 2 or can't change to more than 2 channels(stereo) - This might be caused by having enabled one of the Spatial Sound options (Windows Sonic for Headphones, Dolby Access, Dolby Atmos for Headphones, DTS Sound Unbound). Check that Spatial Sound is Off by right-clicking on Windows Volume tray icon.
  • Sound playback echos. Issues within Windows 10 might cause the enabling of different sound settings, one of them causes sound playback echos that are more or less evident. To ensure you always get the best audio quality it might worth checking this from time to time. See Fix sound echos in Windows.
  • No system sounds. See these solutions.
  • Audio stutter in games. Open Windows Sound (right-click on Windows Volume tray icon-> Sounds or if missing type in Windows search: "change system sounds"), select Playback tab, double click your default playback device (for example Speakers ASUS Xonar Audio Device), go to Advanced tab and in the Default Format option select another sample rate setting and back to your original setting. The described windows and settings look similar to those this picture. (thanks Jean Paul).
  • No sound coming through speakers or headphones. There seems to be an issue where the default playback device is changed upon Windows restart to HDMI or other playback devices (#1). After each restart you can restore the default playback device to your preferred audio card by opening Windows Sound-->Playback tab-> select "Speakers (ASUS Xonar...)" and press "Set default". A more permanent workaround fix could be to disable all other playback devices in Windows Sound.
Windows 10 version 21H1 (May 2021 Update) notes

Known new issues: -

Possible new issues:

  • S/PDIF output not working (#1, #2?, #3?). If you have this issue please report it under this comment. Anyone having this issue should report it to Windows support.
Windows 10 version 20H2 (October 2020 Update) notes

Known new issues:

-

Possible new issues:

  • No sound coming through speakers or headphones. There seems to be an issue where the default playback device is changed upon Windows restart to HDMI or other playback devices (#1). After each restart you can restore the default playback device to your preferred audio card by opening Windows Sound-->Playback tab-> select "Speakers (ASUS Xonar...)" and press "Set default". A more permanent workaround fix could be to disable all other playback devices in Windows Sound.
Windows 10 version 2004 (May 2020 Update) notes

Known new issues:

-

Possible new issues:

  • System crashing when installing the Xonar drivers (#1). A possible solution might be to install the drivers with Windows booted in Safe mode.
  • Equalizer and other sound effects from the cards control panel do not get applied to the sound when using S/PDIF output (#1).
  • Occasional BSOD when waking the system from sleep (#1, #2, #3). The BSOD shows DRIVER_IRQL_NOT_LESS_OR_EQUAL (cmudaxp.sys) as the cause. A possible solution could be to install v 1.71.1 drivers, please provide feedback if this worked for you.
  • PC not booting after the Xonar driver install, issue possibly manifesting in conjunction with the use of Hibernate (Suspend to disk) (#1).
Windows 10 version 1909 (November 2019 Update) notes

Known new issues:

  • Higher DPC latency which may cause massive stuttering (#1). The v1909 can be uninstalled from Control Panel->Programs and Features->View Installed Updates-> select and uninstall "Feature Update to Windows 10 Version 1909 via Enablement Package (KB4517245)". To prevent v1909 update (KB4517245) to be installed again you should use Wushowhide tool (guide on how to use it) or disable Windows Update altogether for the time being.

Possible new issues:

-

Windows 10 version 1903 (April 2019 Update) notes

Possible issues:

Other notes:

  • Windows Sound is no longer accessible from Windows Volume-> Sounds. If you want to control the playback devices, recording devices, Windows sounds you can open Windows Sound by typing in search: change system sounds or by going to Control Panel->Sound.
Windows 10 version 1809 (October 2018 Update) notes

Before upgrading to 1809, you should uninstall the UNi Xonar drivers especially if you have v1.81a installed, as the update process might result in BSOD (#1). As a reminder, in order to avoid a system crash while uninstalling 1825 (v1.81a) drivers you will need to play an audio file before proceeding with the uninstall process. Restart the system after the uninstall process is done.

Possible issues reported so far:

  • Crashes at boot or after walking PC from sleep or hibernation (#1)
  • Audio stops working after some time (#1)
  • Inability to change the number of audio channels to other than 2 channels when using S/PDIF output if you have Speakers disabled in Windows Sound -> Playback (#1).
  • For 1825 (v1.81a) drivers, during the installation of some Windows updates the system might get a BSOD (#1).
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.

  1. Front panel switch v3.2
  2. SampleRate switch v1.2
  3. Microphone Array Enabler v1.1 - Might be useful if you have an microphone array
  4. HDAV HDMI enabler v1.0 - This application hasn't been tested please submit feedback if it works or not. It appears it is not needed anymore.
  5. Acoustic Echo Cancellation enabler v1.0 - Useful for other Cmedia 8788 based cards that lack this setting
  6. Stereo upmix switch v1.0
  7. 7.1 virtual speaker shifter enhanced profile v1.0 - Profile created by Cu. This profile should enhance the effect of positioning in games when using Dolby Headphones and 7.1 virtual speaker shifter. Please provide feedback about this profile. Demo.
  8. Headphones ohm Amp switch v1.0  - Works only with the cards that support this.

2. Additional tweaks

  1. Disable SpeakerCompensation tweak
  2. Increase microphone volume by 3 dB tweak

3. Xonar related applications:

  1. XonarSwitch (beta) - Alternative panel to Asus Audio Center and C-Media Panel. Allows you to control various Xonar’s audio settings, define them as switchable profiles and apply them on-the-fly without having to stop the audio playback.
  2. Front Panel switch (new version) - Application that seamlessly changes between rear speakers and front panel speakers output.

    I've found only ONE driver of the many that would make my Xonar DX 7.1 function on win7. I absolutely WON'T update the driver. I had to work hard to select it from all of the other drivers, so everything stays put, period.

    Thanks, John.

      Please provide details. What problem did you had exactly? If it's something to do with 7.1 sound, tell us which application you are using, if you're using analog or S/PDIF output. Which driver version was is the one that's working?

        [Comment moved by admin from new comment to reply to existing discussion.]

        Regarding Uni Xonar, the only version I can use on Win7/SP1 is 8.0.8.1815 10/03/2012. On an AS-Rock Fatal1ity Mobo, UART MPU-401. Win7 still works quite well, but now I am writing on Firefox/Ubuntu 21.04 because Windows won't merge 2 sound cards. In fact, I am having major trouble in Win10 because it won't even forward optical digital data on multichannel. Advanced testing fails, though the tests on Dolby and Dts go through with flying colors. This is a major problem that I could not overcome. John.

          Does the optical output not work on Windows 10?

            It definitely does NOT, no matter what I do. However, since I am now also working with Linux, I came across something interesting on Jack's site that there might be a version for windows. I downloaded it. It doesn't need any dependencies (lost of head aches with them in Ubuntu if one (like me) doesn't have WiFi in his apartment to directly download on the work computer. I have no idea whether it's just experimental or it's a working version. Will return later.

    Good afternoon. I'm from Russia, I use a translator, so I'm sorry if something is not clear. I have such a problem, on the Asus Xonar D1 sound card via SPDif output, when connecting a home theater, Samsung HT-4500, digital sound is not output. In the ASUS Audio Center control panel, I set 2 channels and PCM output (I tried 6 channels and Dolby Digital Live). The device by default tried to select both "Speakers" and "Digital output" in general, the response is a full 0, which just did not try. I reinstalled the drivers, tried the modified UniXonar drivers, tried the standard ones from the official Asus website, nothing has changed. I thought maybe the problem is in the Toslink - Toslink mini adapter, I bought an adapter, with the usual square SPdif input, connected it to the card, the connector lights up, but that with the adapter, that on a straight line, the reaction is again 0. I began to sin on the receiver, checked it with a friend, through his sound card (Asus Xonar AE) the sound was output and everything worked. What could be the problem? I don't know what to do anymore. Thank you in advance.

      Guys, can anyone at least tell me what the problem is and where to look? I have been suffering for several weeks, for some reason there is no digital sound on the Xonar D1

      Did this issue started only recently, like in the past months?
      What is you complete version of Windows? What Windows version is on your friends PC with ASUS Xonar AE?

      Based on other reports I suspect this issue may be caused by Windows 10 version 21H1 update. Rolling back or installing a prior version will tell us that's the issue for you too.

      Your comment lacks essential information. Please make more of an effort explaining next time.
      1. Did you had these white noises before upgrading to the MSI B560M PRO-VDH motherboard?
      2. Did you notice a pattern when these random white noises happen, like when skipping a youtube video?
      3. Was you Xonar DX hardware ID overwritten or you decided to try some other card ID?
      4. Which IDs have you tried?
      5. Have you verified that the restored hardware ID is correct?

      For ASUS Xonar Audio Center not working, after changing your Xonar's hardware ID do the following: uninstall the Xonar drivers, restart, and when installing the drivers do not select another card other than the one that's detected by the UNi Xonar installer.

      For the random white noises you should check this page for possible solutions.

        1. Yes, on AssRock H110-HDV r3.0 same problem with white noise
        2. Yes
        3. I reverted back old id after this problem with xonar panel
        4. PCI\VEN_13F6&DEV_8788&SUBSYS_82751043 change to PCI\VEN_13F6&DEV_8788&SUBSYS_83271043 and them to first
        5. Yes
        I tried reinstall drivers, all methods not working, only reverted id helped and white noise fixed after all steps.

          I got the white noise when using 24-bit / 44Khz. When I change to 16-bit/44Khz (And turn off exclusive device access) i have had no more white noise issue.

          But other optimizations might also help.

          With the other Xonar DX ID (83271043), I think because the drivers and software can't access and control most of the card functions is why you don't get the random white noises. Or you haven't tested long enough to get one.

            Probably, but it seems I found a solution with white noise and a fading of one of the channels. Add HsMgr.exe and HsMgr64.exe completely to exclude "exploit protection" on all items, and disable their DEP through performance settings, in the same place where pagefile is set. So do it with AsusAudioCenter.exe and MXmon.exe. So far, that it has for a long time of use has helped. By the way, try to make a new installer that removes all spaces in the names of folders from the installation paths, perhaps somewhere with this too, there is an incorrect work of executable files from drivers.

    Question: when I get an inquiry via email and I click it to respond, why this site doesn't direct me to the inquiring individual's post? I always end up on a page that doesn't contain it. This is why my reply here is a post because the Reply button doesn't lead me to the person that sent me the email.

    Sorry, John.

      The e-mail link didn't direct you to the inquiring individual's post only in one instance, with Sergey's comment that was made in that separate discussion thread that was to be deleted. For that, it didn't direct you to his exact comment because I moved the comment, and instead of his original text, the linked comment had the message "Comment moved here".
      Only now, it does not jump to any comment because after your last comment, I deleted that discussion thread.

      For all others comment e-mails I think you where redirected to those specific comments. I checked and the e-mail Reply links are working fine, if they are not working for you, it's an issue on your end.

      Even if any of the links don't properly work for you, beside reporting they don't work, you should have made the small effort to look for the comment (manually or using Ctrl+F and typing a keyword for the e-mail comment notification) and reply to them instead of writing new comments.

    I don't know whether this comment/request belongs here. Moderator, please let me know.

    I know that 2 sound cards cannot simultaneously be run in Windows (the Recording section of the Properties tab won`t do because of quality reasons in a DAW environment) . However, could anyone modify the Xonar driver such that it'd detect the 2 Xonar DX 7.1 cards in my computer/Win7 so that I'd aggregate them via jack2?

    Thanks, John.

      I know that the Windows enumerator is not designed for multiple cards performing at the same time and that problem is raised time and time again. I tried the old method with the Recording tab, but of course there's noise and delay, so it's not propitious for using it in a DAW environment. It seems to me that, apparently, there' s no solution for what I intend to do in the Windows environment. I tried jack2, no dice because finally Windows would output only on 2 channels, although in the DAW (Sonar Studio 8.53) I can see all 22 outputs (2xXonar 7.1 + 6 from the local MoBo sound system. This is why I may to go (alas) to Ubuntu Studio. Well, good luck to me:). John.

      Again you are not using the comments Reply function. You again wrote 3 NEW comment's instead of replying to existing discussions.
      Ignore the Reply button in the comment notifications e-mails your receive. On the website, when replying to an existing discussion use REPLY button floating on the right of the comment you are replying to. If you can't do this, your comments will no longer show up.

      Now to the question you kept asking. The simple answer no, I can't help you.
      I don't know what's going on, I am not familiar with the software you are using or with multiple soundcards configurations. Your issue be it with the software configuration, Windows, or the Xonar cards driver configuration, whatever it may be, if there is a solution, it does not appear to be an easy one. Then there the fact that you have some difficulties understanding and explaining things which makes the whole thing a lot harder. I have neither the time nor the patience for this.

    I no longer have an output from my SPIDIF on my Xonar D2X card. I have been using the standard Asus drivers for years without any problems, however whilst listening to music the other night my output went silent, when I checked my computer I saw that my pc had updated to windows version 21H1. I have checked my amplifier, optical cable etc and everything is working. The optical cable end is showing bright red suggesting to me that there is a strong signal coming from the card but yet still no sound. All settings in Audio center are correct nothing seems out of place but no audio. I am using Windows 10 pro 64 bit. Any ideas?

    Did anybody try Windows 11 and can confirm that this driver still works with the current version of Windows 11?

    I instaled UNi Xonar 1816/1821 v1.71.1 for my Xonar DX and everything is working fine, no bugs or any kind of problems. My config is Gigabyte AX370 Gaming 3/R5 1600 with W10 Pro 21H1 in latest updates. I have to say that this card sounds pretty much better than my old SBZ, waaaaaaaay better than my oldest SB0880 Titanium Fatal1ty.

    I will have to change my PC and would like to know if it's possible to transfer my settings (using 1.81a) ?
    If it is, which files do i have to copy/paste from the directory ? "installsettings.ini" ?
