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).
Windows 10 version 2004 (May 2020 Update) notes

Known issues:

-

Possible 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.
Windows 10 version 1909 (November 2019 Update) notes

Known 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 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.

  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

May be used instead of Xonar Driver Restart as it is quicker and does not affect running applications. This will cause a temporary 1 sec switch between rear and front panel outputs.
  7. Xonar-EQ - Control Xonar equalizer settings from your Android phone or tablet. By Sascha.

4. Auxiliary audio applications:

  • ASIOConfig - ASIO configuration viewer/changer that can be used when you can't access the Xonar ASIO Configuration directly. By djdecks.

    The UNi Xonar W10 1825 v1.81a r2 for Win10 only or I can install them on Windows 7 64bit?
    My sound card is Xonar D1

    Reply

    Hi! Thanks a lot for your project and for still keeping it alive!
    I'm using a Xonar D1 on Win 7 SP1 x64, I've just updated from 1.75a r2 to 1.80a r3 (config: C-Media with GX, cleanup, upmix) and I've got some issues with default settings:
    1. Xear3D is turned ON;
    2. Speaker volume got reset to 50%;
    3. Front Panel Microphone option is enabled (not sure if it should).

    Reply

    • CarvedInside25 Oct 2020 @ 23:23

      Thank you for these reports and suggestions.

      1. Xear3D(GX) is turned On by default because there is no Xear3D button on WinXP and at the time I added the "C-Media Panel (GX enabled)" configuration I thought anyone installing with this configuration would want this turned on. Maybe it would be better to have GX disabled by default and have this configuration renamed to something like "C-Media Panel (GX available)".
      Any particular reason you installed this instead of "C-Media Panel" configuration? Are you using GX in any games, if so, which ones? Doesn't it cause crashes or bluescreens for you? Or, are you using MagicVoice and other Voice Effects that depend on HsMgr (GX) processes?

      2. This is what the Xonar drivers do by default and as far as I can tell there is no way of stopping them from setting volume at 50% when installing the Xonar drivers.
      Will see if I can dedicate the time to make some program to store the previous volume and restore it after the driver is installed.

      3. Without changing any setting and microphone being connected to the back of the card, did it work? I am aware of a UI bug showing front panel microphone being enabled after a new installation. Never the less it is something that I should look into fixing, hopefully if it does not break anything else.

    Hi Everyone,

    I bought recently Asus Xonar D2X secondhand. I updated BIOS, updated chipset driver, tried several PCI-E slots. Unfortunatelly during driver instalation PC freezes... I tired to install drivers from Asus website but installation don't even happening due to error "Asus Xonar D2X Audio Device does not exist, the installation program will be terminated now ". Does it mean that my audio card is defective?

    Couple of days ago I bought MSI B550 Tomahawk and installed my Xonar STX II in bottom pciex1 slot and it looks like on B550 STXII do not trigger BSOD when changing output. Only 2 days past since but I'm using it without any problems. With X370 with latest bios using STXII was quite a nightmare. Will test for couple of weeks and report back on stability.

      Thank you for report. Please repost this under the proper page. Mention if you changed that PCIe slot speed and also mention which X370 motherboard you had. Keep us updated with how things went after a couple of weeks with a reply to original comment on the proper page.

    Thank you for your wonderful work! I have been using your drivers for several years now. Do you think that there will be other evolution of the driver for win 10?

      Don't think C-Media, who makes the original drivers, will ever release any new audio drivers for the Xonar cards. As for UNi Xonar fixes and improvements I don't have anything significant at the moment. You can read more about the process of UNi Xonar driver releases in the FAQ Q&A 13.

    Hello!

    I have Win10 with all the latest updates, and the UniXonar 1.80a installed (in "driver only" mode) for my Xonar DS card. Playback with JRiver is all-around fine with the "Default" Direct Sound device, but if I choose the ASIO or the WASAPI option in JRiver things getting messy. With ASIO the playback constantly stutters, hiccups, hangs or pauses as I operate with other programs (like Explorer or Chrome) and with WASAPI there are also some hiccups, not as many, seems OK for while and than just causes the entire Win10 to "freeze" unexpectedly, so only the reset button helps.

    What kind of solutions, workarounds do you suggest to get ASIO and WASAPI working as it should?

    Thanks!

      Some questions:
      q1. By "driver only" mode you mean "Low DPC Latency" install configuration?
      q2. Which version of JRiver you currently have?
      q3. Tell me your complete Windows 10 version.
      q4. Did ASIO or WASAPI playback ever worked for you alright with the Xonar card?

      Try each of these both with ASIO and WASAPI playback:
      1. Completely close JRiver player and then run it as administrator (right-click and select "Run as administrator").
      2. Disable Windows UAC after which restart the system.
      3. Different UNi Xonar driver versions.
      4. Check your system's DPC latency see if it's not reported as being to high by LatencyMon.

      Let me know if any of these worked.

    Hi,
    Using Xonar Xense with the PC350, now the volume of the right headphone speaker is very low to non existent. I confirmed that the headphones are OK by plugging them to my phone, and to the on board sound card, working fine for both cases. I also tried plugging the headphones to the front panel (which is connect to the Xonar) and still sound only comes from the left speaker. I checked the relays on the card the those seem fine, switched the 1 and 2 Op-amps and still the same problem.

    Is this a hardware issue or maybe caused by the driver?

    Please note that the 7.1 speakers connected to the card are working fine.

    Thanks.

      Your issue sounds just like this one. Your comment is so similar to the point I have to ask if you previously wrote that as well?

      Which Windows do you have? If it's Windows 10, tell me it's complete version and build number. Which drivers have your tried?

      I think it's most likely a hardware issue with the card with the components related to the headphone output. If you want to be 100% sure that this is not a software issue, try to see how the card behaves in another system, preferably with Windows 7, and of course try with different driver versions.

        No, that's not me.
        But WOW though, that guy did exactly like I did and have exactly the same issue! I wonder If he was able to find the problem.
        I even ordered some new op-amps to try out, but according to his message that won't solve the problem. I went further with visually inspecting the PCB for damage and checking the relays one by one.

        I have Windows 10 Version 2004 OS Build 19041.572
        I have tried both UNi-Xonar-W10-1825-v1.81a-r2 and UNi-Xonar-1823-v1.80a-r3 which I'm currently running, both with Low DPC Latency.

        I just tried a Windows 7 system on the same machine with the following drivers:
        UNi-Xonar-1815-v1.64-r3
        UNi-Xonar-1822-v1.75a-r3
        UNi-Xonar-1823-v1.80a-r3
        Same issue, restarts in between installations.

        Don't you think this it's a little bit weird that this happens to two different people with 2 months? I mean coincidences happen but this is just strange.
        I will wait for the op-amps before trying to diagnose further.

        Any ideas are highly appreciated. Thanks for the good work.

          On my side I’m still having the issue (referenced here), for now I was not able to fix it.. for sure it’s an hardware one, something is broken but I don't know what and how to identify it. Only thing that I’m sure is that it’s not coming from the jack itself since when you are connecting the front panel there is the same issue.

          Based on what you've tested, I don't believe this to be a software problem.

          Yeah, it's a bit strange that you both have the same problem so close to each other.
          Every electrical component has an operating life, a number of on/off cycles, and there could also be some degradation of the chemical materials that are in the capacitors, for example. It could be that a specific component on most of the Xonar Xense cards was of poor quality and degraded much sooner and thus you now have some or even many Xonar Xense cards that have this problem, instead of having it in lets say 10 years.

          I have to say something. I'm not aware of you sending me a donation and your are using an adblocker on this website. That, to me, does not show any appreciation for my work and time. So if you previously donated, it would be good to know. You can let me know with an e-mail from that e-mail address associated with the payment.

      Install the UNi Xonar drivers with "Low DPC Latency" or "C-Media Panel" configuration. Let me know if it worked.

      You should make a comment on the Xonar and AMD Ryzen AM4 motherboard compatibility with your configuration (Xonar card, motherboard, CPU) and if it works properly or you get a BSOD when changing settings and so on.

      icue is simply a bad software. It is bad no matter what, basically. I offer this at least since I just escaped icue's garbage. Get an arctic freezer or something and ditch corsair coolers. That awful bloatfest will take ~5-10% cpu over the menu settings AT IDLE

      to make it any better at all I had to -affinity to one core, low procsses and low i/o settings through process hacker- etc etc. Delete all the random drivers icue installs for no reason. There are literally programs it runs that do nothing. Insanity.

      that + the razer software will conflict with everythng. I hate proprietary stuff.

    Hi,
    I got win10 20h2 fresh installed and the latest asus driver does not work to install (reason no card pluged in...)
    The newest UNi Xonar W10 1825 v1.81a r2 tells me Driver installation failed.
    There is no audio card in the device-manager and not shown up if I start a search.
    I already tried to enable the test mode

    even if I try this:
    1.Download Uni Xonar Drivers http://maxedtech.com/asus-xonar-unified-drivers/
    2.Install them in Low DPC Latency Mode
    3.Use XonarSwitch for configuration http://maxedtech.com/xonarswitch-beta-testing/

      1. Which audio card do you have?
      2. Does the card show up at all in Device Manager? It can be detected as "ASUS Xonar..." or it could be as a unknown device like "Multimedia Audio Controller" or "Unknown device".
      3. When you launch the UNi Xonar installer, does it show "Error: Compatible audio card not detected" message? Is the card properly detected by the installer?
      4. Right prior to installing Windows 10 version 20H2, did the card worked for you? Which OS and version did you have then?
