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 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.

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

Known issues:

  • Higher DPC latency which may cause massive stuttering (#1).

Possible issue:

-

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.

    Can U explain me why default volume after installing drivers is set to 50? I should increase it to max or dont touch it and only using volume in apps and amplifier?

    Reply

    • CarvedInside20 Jan 2020 @ 21:01

      50 was the default volume of the original drivers. Depending on their setup people use lower or higher volume so 50 seems a good start for both. Ideally, you would want the audio signal that is coming out of the card to be as strong as possible and control it in the amplifier. It does not matter if you control the volume in each applications on Windows Volume mixer.

    hi CarvedInside, i just saw new drivers for stxii dated 25dec 19 on the Asus site,did they are new version ones or same as old? i still useUNi Xonar STXII 11.5 v1.80b r3, + disable speaker compensation which are the best combo for stx2 ,sounds way better than all others and without problems

    Reply

    • CarvedInside21 Jan 2020 @ 16:12

      Thanks for the head up. I've checked the driver files and there is nothing new, it's all exactly like the previous driver released in 2015. They just removed the "Beta Version" tag from the name.
      Glad to hear. 🙂

    Sorry for the dumb question but I have W10 latest build, is it better to get the latest version (1825 v1.81a r2) or the most stable (UNi Xonar 1816/1822 v1.75a r3)?

    Reply

  4. Bane28 Jan 2020 @ 15:35

    Hello CarvedInside, first of all thank you very much for your work. I have used uni drivers for Xonar DG for years (last one was installed on W10 1903). After doing a clean install of 1909 on the same machine, Windows is freezing ~half a minute after booting up. It basically becomes a slideshow, where screen is updated once every 10-15 seconds (caps lock takes just as long to enable). Even during the installation of uni drivers, Windows freezes for about 15 seconds and continues "successfully". Event Viewer reports failing to load drivers for cmudaxp.sys. I first tried 1.81a on a clean Windows install, then 1.80a after another format and finally 1.75a r3 after ticking "Cleanup drivers" in the uni installer. All three versions are having the same issue. Issues are completely gone when I uninstall the uni drivers.

    Do you have any clue what could be causing this? Should I try "Disable Driver Signature Enforcement", even though that wasn't necessary on previous Windows installation?

    Thank you in advance.

    Reply

    • CarvedInside29 Jan 2020 @ 03:38

      I tested things today on my system, on an updated Windows 10 version 1909 and I am not having any issues. So the issues seem to be particular to your system.
      Check that your card is properly plugged in the slot. Try a different PCI slot. Try again with Windows 10 1903. Try "Low DPC latency" configuration in the UNi Xonar installer.
      Don't think "Disable Driver Signature Enforcement" will do anything but if you don't have anything else to try you could try that.

      Have you changed anything between when now and when it last worked?
      Provide the error log from the Event Viewer.

      Reply

      • Bane29 Jan 2020 @ 10:47

        Thank you for your response.
        There were only two changes compared to previous system: One was changing the PCI slot after re-assembly of the machine (I'll put it back into the previous one) and the other is fresh Windows 10 1909 installation. Always used the Low DPC latency installation as well.
        Will update with results after trying the old PCI slot and I'll try to get the error log.

        Reply

        Changed the PCI slot and first issue was that SUBSYS number for DG was off by 20, so installer wouldn't recognize the card even though it was showing up in Device Manager. Re-seated the card and SUBSYS was back to it's original. Installed 1.80a drivers and it seems to be working for now or at least it hasn't been freezing so far.

          Good to know. Besides the card maybe not being seated properly, the pins in those PCI slots or those from the Xonar's PCI connector could be dusty or dirty. If you still have problems, you should clean the PCI slot with a vacuum cleaner and a brush, and for the card's PCI connector, you can clean that with a paper towel sheet or cotton and rubbing alcohol.

          Especially if you haven't donated previously, it would be nice if you thought of compensating me for my work and time with a donation.

    A continuation from this discussion.

    Hello,
    I tried some things to eliminate my buzzing from the STX II 7.1 when my graphic cards has to work hard:
    1. External Molex Power Supply = no success.
    2. DIY EMI/RFI-Shield with 1mm Aluminium in Carbon Style = nor success 🙁 Shield is connected to the PC case.
    Some pics are here:

      Is your PC connected to a grounded electrical outlet?
      The EMI from the GPU could be picked by the cable that connects the STX II card with it's daughterboard. If you remove the daughterboard or disconnect it's cable from the STX II, do you still have the issue?

      These shields are basically pointless, regardless of the fact sound card makers make them seem like a big deal. If you're getting interference, it's most likely coming over the PCIe bus from the MB.

      Also, try touching the case to see if the interference changes and/or goes away. Might be a sign of ground loop unrelated to the GPU.

      Another thing to try. You could slightly lower the GPU clocks for better efficiency, lower the power limit and undervolt the GPU with MSI Afterburner. For undervolting see this guide.

      Let us know if you manage to fix or mitigate this issue and how you did it.

      Next time, please take the time to write your message properly. When you write a new sentence, you should use space and capitalize the first letter. The name of the products, again with capital first letters, the card is not "asus xonar d1", it's "Asus Xonar D1", the board is not "asus x370 prime-a", it's "Asus X370 Prime-A". It's important the message is clearly readable and others can easily understand you.

      Also, do not post multiple messages everywhere as it won't make it so that we will help you faster or at all. If someone wants to answer you then they will.

      Another thing, so you ask me for my help, but when I asked you to disable the adblock or make a donation, what did you do? I'm not aware of you making any donation, so it means you ignored those even when you asked for help. Don't you deserve the same treatment?

      Anyway, let get this over with. Here are some things you could try:
      1. It's unclear to me if you have both cards plugged in. Try with only 1 card.
      2. Update the motherboard BIOS to the latest version.
      3. Try the Xonar card in different PCI slots.
      4. Try with UNI Xonar v1.71.1 drivers with Low DPC Latency configuration.

      Mention what CPU do you have and let me know if any of these worked or not.

    I don't know why and how... but I think my STX with drivers 1.81a sound more cleaner and bass more powerful, it only with 1.81a, with 1.80 sound more dry how like official asus drivers. But 1.81a drivers have problem, sometimes after sleep mode, only 1 channel starts to work and ~x2 louder, I fix this problem via switch to Speakers and back to Headphones, but I worried about my headphones, because they work in 300-600ohm mode.

    • CarvedInside07 Feb 2020 @ 05:01

      How often does it start x2 louder? Are you sure you don't have the same behavior with other drivers? What motherboard do you have?
      As I've written in the v1.81a release notes, the RightMarkAudio tests that I've made didn't show any significant differences between v1.81a and v1.80a or other drivers. Now, I have a Xonar DX and tested it without any impedance "boost".

      I don't have a solution the the volume issue after resume from standby. As a quicker fix, you could try the "Xonar Relay Restart" program see if it works in you case. Let me know how that goes.

    This Asus Xonar works great if you know how to use it. K-Lite Codec Pack from https://codecguide.com/download_kl.htm it's good stuff and has it's own player, it works great and it's better than most of the other players, better than VLC player or BS Player. You can change any channel like up to all speakers mostly every single speakers and stuff. The Xonar card just works fine with this media player but it's kinda confusing to use, first couple days you look all settings and stuff you can figure it out all your self mostly! I connected my Logitech Z906 + old Logitech 5.1 now I have 7.1 surround. I removed the bass from the other the speakers, I unscrewed and removed it so I can only have sound from left and right, and it works perfectly.
    Tests for Dolby 5.1 and 7.1 surround sounds can be found at https://thedigitaltheater.com/dolby-trailers/ , you can just download most 7.1 and 5.1 surround sounds there and test them how they work or even use FruityLoops to make music and test each speakers. I'm glad I got that shit working. 😀 Try that and this player, it's good! 🙂

      If you want your comment to have any value to someone else, please take the time to write it better. Use sentences and start the sentence with an capital letter. Write the product names how they are originally written or at least capitalize their first letter. Use "I" instead of "i". Don't use unnecessary abbreviations like "u" instead of "you". You could use the free version of Grammarly to help you in some of those cases.

        I think starting sentences with lower case is pretty normal in internet (in informal communication) and don't lowers the value of comment.

      Many people have problems with their Ryzen systems and Xonar cards, I have made a dedicated page for this topic. It's currently shows on the front page, the Xonar category, it's mentioned in this very page and it would have also showed at the top if you've googled "Xonar Ryzen"...

    Hello. I have connected my headphones (600Ohm) to the analog port and my 5.1 Speakers to the digital coax port of my Essence STX II. I set the gain to 600 Ohm for the headphones and the SPDIF output to PCM but when I do that I won't get any sound out of the headphones. Just the 5.1 Speakers are working with enabled PCM. When I disable PCM the headphones are working fine but I want to easily switch sources over the Windows menu. Has anybody had the same problem? How can I fix this? It's bothering me because the original Asus drivers aren't good for anything.

    Thanks so much for these drivers. The latest drivers work great for me in W10. Only thought to update them today (16/02/2020). My previous ones caused a frequent annoying clicking/popping sound in Foobar2000. Perfect now. Huge thanks! 🙂
