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.

> Find out which Windows version you have installed.

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 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 drivers you will need to play an audio file before proceeding with the uninstall process. Restart 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 (#1). Problem seems to manifest only if you have Speakers disabled in Windows Sound -> Playback.
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.

    I have an Asus Xonar DX 7.1, which is the correct driver? Having issues getting audio through this card on Windows 10.

    Reply

    • CarvedInside31 Dec 2018 @ 22:16

      Normally any UNi Xonar driver should work, but is some rare cases older drivers may work better. Do you have the issues with v1.81a? Try 1.80a, 1.71.1a and 1.80b.
      What kind of issues are you getting? Which Windows 10 version do you have? Did the issues started after some event, maybe a Windows update?

        Just install the card, haven’t got it working yet. It’s recognized in my device manager and i can visually see the audio coming through but no sound. Win10 version 1803.

          Did you just bought the card and installed it? Was the card new or used? Are you using the analog or digital (S/PDIF) connection?

          • Jeremy01 Jan 2019 @ 05:41

            I think the card was used, bought it off of amazon. And I’m using an analog connection.

              Things you should try:
              1. Make sure your speakers/headphones are currently working and are not the problem. Also check that you’ve connected them to the proper DX output jack.
              2. In ASUS Audio Center or C-Media Panel set the Speakers to 5.1 and Audio channels to 6, connect the speakers to the rear channels output instead and try a speaker test.
              3. If you case has a front panel audio jack, connect the panel to the Xonar DX card. In the ASUS Audio Center or C-Media Panel change the output to Front Panel Audio. Connect the speakers to the case front panel audio and test them.

              If none of those work I think your Xonar DX card is defective.

    I’ve been using UNi drivers forever now and they work fine, however recently I’ve started using things like VoiceMeeter and tried to have my input be bit-perfect using their “hifi cable” (Pretty much offering me a normal audio device to ASIO troughput to VoiceMeeter), as well as the cmasiopPCIX ASIO device offered by the driver, however I’ve encountered the issue that the driver is crashing, very frequently (Multiple times per hour). Playback works fine at 1ms buffering on either end, but at some point the device seems to pretty much to simply freeze, causing VoiceMeeter’s engine to freeze as well and give me the usual “bluescreen soundbuffer loop”. Increasing the buffering does not fix the issue. This problem only happens when going trough the cards ASIO. Using a different ASIO device (Say the monitoring of my microphone), or just kernelstreaming to the card works fine, however I’d love to use ASIO as that lowers the DPC latency by a lot as well as offering less delay and bitperfect quality (Not that I’m an audiophile or anything but free is free right?)

    I have some problems with my STX (first edition). Used to sound fantastic with my Edifier 2.1 speaker set, but over time the sound lost dynamics, got distorted and there are sometimes interfering noises. I tried the Xonar Unified drivers, but it didn’t help. Most likely, it wasn’t a driver issue anyway, because it had worked fantastically before with the official dirvers. I thought it could be due to an old and maybe outworn mainboard, but upgrading my system to new AM4 platform didn’t help as much as I has desired. I then suspected the STX itself to be the culprit and tried to replace it with an STX II. Then I found out this card isn’t compatible with AM4 platforms, as even admitted by ASUS. The B450 chipset isn’t included in ASUS’ official statement about his, but I did run into the reboot issue when trying to install the STX II drivers (original ones as well as the alternatives ones here) on an MSI B450 Gaming Pro Carbon AC. The only remaining thing I could try (apart from setting up an Ittel system, which I don’t want) is getting another STX (first edition). Does anyone know a way to get (a preferably new) one?

    I’ve been using my ASUS Xonar DGX and your drivers for the past two months and everything worked great until yesterday. My mic just stopped working for some reason. When I tried to uninstall your driver my PC crashed all the time, so I reset windows and reinstalled your drivers, but it still doesnt work. My mic works on my onboard soundcard and I unchecked the “Front Mic” in the Asus DGX Audio Center.
    Any ideas why it stopped working and how I can fix this?

      I don’t know if you’ve connected the microphone to the back of the card or to the case front panel.
      Probably it’s a hardware fault, maybe a the card’s microphone jack has become partially unsoldered or some component on the Xonar card is dead. You could try connecting the microphone to the case front panel microphone jack and enable Front panel mic it in the Xonar audio panel if you previously had the microphone connected to the back of the card, if not, do vice versa.

      For the issue which you had with PC crashing each time when uninstalling the drivers, maybe you had v1.81a drivers and you did not follow the specific instructions (playing a audio file when uninstalling).

    Is it possible for you to update these uni drivers to the latest C-Media base driver and eventually audio center (depending on its source)
    Also some accounting for Win10 1809 / new testing and/or development would be appreciated

    After updating to Windows 10 October Update occurred last week I have audio problems. It occurs that the audio on some occasions does not work or better does not feel and I am forced to restart the computer.

      Thank you for the info. Hopefully you can provide the additional information:
      1. As I understand, the sound completely stops after some time right?
      2. When this happens, if you check the Windows Device Manager, what is the status of the Xonar card (working, missing,etc.)?
      3. When this happens, if you right click Windows Volume->Sounds->Playback devices, is the Xonar card set as default playback device (green checkmark)? It’s volume meter does indicate that sounds are playing?
      4. Which audio card do you have?
      5. Which driver versions have you tried?
      6. Do you use analog or digital (S/PDIF) output?
      7. Please mention the complete Windows 10 version and build number.
      8. Please clarify “or better does not feel” statement.
      9. These issues started only after installation of the Windows 10 1809 October Update?

      If you install drivers other than v1.81a, you could use Xonar driver restart tool. On v1.81a drivers you might get a BSOD if you try the tool. If you try it, let me know if this tool fixes the problem without the need to do a system restart.

      Thank you for the information.
      1. Tell me your complete Windows 10 version and build number.
      2. Are you saying that when changing number of audio channels or chaning output to S/PDIF PCM in the ASUS Audio Center, the ASUS Audio Center exits or crashes?
      3. Have you tried changing the settings with XonarSwitch?

        1. 1809 (OS Build 17763.195)
        2. Tak AsusAudioCenter (32) is close id ended after Audio channel choosing or SPDIF Out selecting.
        3. XonarSwitch after start say “Xonar Speakers are disable”, but I have sound from S/PDIF Output.

        After that, what? Speakers are disabled? Oh yes, for years… But now, I do´t now what is changed in actual Windows, for now I need enabled speakers (otherwise I can now disabled S/PDIF). Strange, but result is, everything is now OK. Thanks for your patient.

    I can’t seem to make daughterboard work for STX II 7.1. I’ve now installed original asus drivers and it’s silent.
    Is this W10 problem or do I have faulty card?

    I tried updating to Windows 10 1809 via the Update Assistant but always got a BSOD.
    In the 3 times I tried it always BSOD and revert to 1803.
    Its a SYSTEM_SERVICE_EXCEPTION on cmudaxp.sys.

    That file seems to be part of the Xonar drivers.
    Maybe I’ll try to uninstall the Xonar drivers before updating.
