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 (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.

    Windows 7 x64 here and UNi Xonar STXII 11.5 v1.80b r3 installer does not work for my Essence STX II card, I always get:
    Installation failed, Compatible driver was found but its installation requires that you press “Install” when asked blah blah.
    I NEVER saw anything that required me to press “Install”.
    When I disabled “clean drivers before install”, then I saw more error messages: “driver installer failed to install, but before running alternate you have to agree to clean old drivers”, I agreed, and then I saw 1 box with “Install” button. But that did not help as installation still failed with that same message.
    I also tried UNi Xonar STX II 11.5 v1.75b r3, but all it did was loop “Please plug-in UNi Xonar Audio device!”, no idea what that is.
    I installed v1.80a r3 with no problems. And I’m using patched AsusAudioCenter with no issues.
    Am I missing out much when not using “b” variant for my Essence STX II card?

      Run the 1.80b or 1.80a driver installer without going on with the install procedure. What card does it autodetect? If your card is detected as a different card then that would explain the problems installing 1.80b. In this case the card EEPROM has been overwritten, you can read here how to restore it.

      The drivers 1.80a are fine for STX II.

        Windows told me the cause when I tried to manually install B variant: the service name was already taken. This error does not happen with installer A.
        So I simply deleted the leftover service (STXIIService) that for some reason installer B’s uninstaller did not delete and then installer B applied drivers for my card without any problems.
        STX II drivers are actually a lot better for that card: variant A gives warmth to sound, reduces some unwanted noise, but variant B replaces warmth with more realistic sound, adds better, more fluid bass, basically allows that card to give its best. Especially noticeable with good headphones.
        Thank you for making these drivers happen!
        Btw, I did not receive any notification by email about follow-up comment. Not even under spam.

          Interesting, never had this before. I will check why this service was not deleted by the driver cleaner and make the necessary changes.

          Regarding the e-mail notification. Have you received the e-mail with the subject “[Subscribe] Comments on MaxedTech – please confirm” and confirmed the subscription by clicking “Confirm follow”?
          You can check the status of the subscription here. Let me know of the status and if you still do not receive the e-mails.
          Edit: Just checked the comment subscription function and it works for me.

          Thank you for the information.

    Windows 10 x64, Xonar DGX, driver v1.81a r2, Windows 1803.
    Conditions at the moment:
    1. Realtek turned off in BIOS
    2. All other sound devices turned off in Windows control panel.
    3. No “Dolby access” or “Dolby Atmos” installed.
    4. Sound volume is at 76.
    But, anyway, after all these manipulations the Sound worked for about an hour and got frozen, all media stopped working. The sound appears only after a PC restart.
    Could you advise anything on the subject for a stable system work without any headache? Cause it`s really mind-blasting. Tried earlier driver versions – the situation is even worse.

      Thing to check and report back:
      1. Was there a event after which you started having this issue(installing some Windows updates, installing an application, installation of Windows 10 etc.) or did you have this problem since getting the card?
      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. When this happens, type in search “App volume” and press Enter. Here it shows the playback devices for each of the current applications. Even if the Output is set to “Default” for an application that is no longer producing sound, you could manually set it to “Speakers ASUS Xonar..” (if this is the one you are using) and see if sound starts working again. You should revert it to Default after checking as you would have problems when changing to a different audio card.
      5. When this happens, if you use Xonar driver restart tool to restart the card, does the sound start functioning again?
      6. Do you use analog or digital (S/PDIF) output?
      7. Are you using headphones connected or that sometimes connect to the front panel?
      8. If you use the onboard audio card instead, does the issue still happens?

        Plus to the above:
        1. Energy saving disabled.
        Answers to your questions:
        1. The problem since installing the card/
        2. In Device Manager the card is working.
        3. When this happens the Sound bar like starts playing and froze – the same is in the Device manager with volume meter.
        4. Even if all apps set to Xonar nothing changes.
        5. THE ONLY thing that helps is your Restart tool and just a PC restart.
        6. I use 5.1 analog output – not S/PDIF.
        7. Don`t use headphones.
        8. Onboard card disabled in BIOS.

        I suppose it`s an important issue: the Sound disappears in different timings even if no actions are made like installing or deleting other apps. It`s just like someone put everything on Pause.
        Thanks for the help with the Restart tool.))

          Unfortunately, this Repair Restart tool doesn`t help any longer: the sound stops, click on the tool and a message appears ‘hsmgr.exe not found’, although it`s running all the time.

            I think the error was with hwdmgr instead of hsmgr. These are totally different files. Check if hwdmgr64.exe is still located in “..\Xonar_driver_restart_v1.1\Tools\” as it may have been wrongfully deleted/quarantined by your security suite or you’ve just moved “restart card.exe” without the Tools folder.

          3. The volume bars no longer move with sound activity, right? Are they frozen in “not active” or “active” state?
          8. I am suggesting you try using the onboard audio instead and disable the Xonar card too see if this still happens while using the onboard card.

          Additional things:
          9. Which motherboard do you have?
          10. I think you should check the Xonar card in a different PC, preferably with a different Windows version, it might be that your card has a failing hardware component (maybe the DAC) and this shuts down at some point and by restarting the card that component gets started again.

    Have you considered making these drivers open source?

      Are you asking about the audio drivers or just my part (the UNi Xonar installer with it’s features)? Because the audio drivers are made by C-Media and it’s up to them to decide if they want to open source them.

        I mean, if you can offer modded drivers without ASUS or another company cracking down on you, then I’d not see any reason why you could release the source code as well.

          He doesn’t have the source code for the drivers, that’s what he was trying to tell you. He’s just modding drivers that are released by C-Media, so if you want the source code, you have to ask C-Media.

          (And when I say “just modding”, it sounds way too dismissive for the amount of good the modding does for us.)

            I’m sorry. I didn’t realize that the drivers couldn’t be modded, as they are still signed. I still stand by the fact that I believe that the installer should be open source. The hardest thing to do would be finding a license (or creating your own).

    Hallo guys,

    first of all, thx for your effort keeping this great product alive!
    I updated my system now to Win10. Since then, Iam having now constantly issues with the sound in Battlefield 5. The biggest problem is the popping and cracking sounds in game situations with many explosions etc. Sometimes this overload leads to no game sound at all and I only hear the voices of the soldiers. Then I have to restart the game.
    I didn’t have this issues with Win8.1.

    I uninstalled the NVIDIA HD Audio driver, and the Win10 Dolby Atmos effects are deactivated.
    Sampling run with 44.KHz, 8 channels, no Dolby Headphone active.
    in the Windows Options, the sound output runs with 24 bit, 44100Hz

    I have no idea what to do.

    Greetings

    Hello. First of all, I wish to thank you for the effort to keep the drivers up and running!
    Now, to my issues, which I find rather weird.
    The first one is with the drivers themselves. I’m using a 5.1 audio most of the time and, sometimes, I get this weird problem – my right speaker stops producing any sound. It is not common, it doesn’t really happen often. I’m sure its not a faulty speaker, since the problem continues if I switch to headphones and it fixes itself if I restart the computer. At first, I thought it was some cheeky windows bug, since few of the times, when I went for the restart, a windows update went off. But most of the time, there are no updates involved.
    Now, for the second issue, which is more annoying than problematic. I’m using the Dolby Home Theater addon from here, I loved it ever since it came native with my old laptop and the thing helped me out when I was searching for a solution to put audio on all speakers when using stereo multimedia like youtube, which gave me audio from pretty much the left and right channel only. Anyway. The sound enhancements are working great (normalizer, the two equalizers and the other options), especially on quiet sources. But very very often Dolby manages to give me effects on only one source. For example – I want to play a game like Stellaris or Elite Dangerous on my main monitor and listen/watch youtube videos on the other. While the game is blasting on full volume, the video plays flat without Dolby enhancing it. If I start a video first and then load the game, it will work on the video, but will ignore the game. Sometimes, it fixes itself – while playing it will catch on to the video and give it the effects, but most of the time it doesnt. So far, I found out that if I switch from 6 channels to 2 channels and back to 6, it will fix the issues and most of the time I do exactly that, but some games stop producing audio if the channels are changed while they are active.
    As for my system: I’m using a Xonar DX, from the audio center I’m set to 6 channels, 192 KHz, 24 bit, 5.1 speakers with the virtual speaker disabled. No audio effects are active, except for FlexBass, which I really like.

    Any suggestions will be appreciated.

      Hi.
      1. The problem with the sound loss on the right speakers is probably caused by a hardware issue with the card. Instead of a system restart, check the methods presented at FAQ Q&A26 are they a faster and more convenient way of solving this.
      2. I don’t know about that.

    Hello I am using xonar ds (driver 1.81 latest one) with w10 pro version 1809. I realize a weird issue nowadays that especially for same games (like sekiro) when I enable dts connect and set 5.1 I get 2-3 second random freezes while playing and had to disable dts 5.1 and switch to pcm stereo. Also I get weird cracks and pops while using dts after playback stop . Reciever immediatelly enters pcm till next music playback that’s why in every music start you get a delay and every stop you get cracks and pops. Is there a way to solve this issues. I think first one seems to be related with driver itsef and it has been a while since the last driver released. I think sound card manufactures just fool with us and neither creative nor asus is customer oriented and they just don’t give a …. about the users. We are just a bunch of people around who still find onboard sound is nothing but crap but this support issue drives me crazy and I will never buy a sound card again.

      Hi.
      You could try with some of the previous drivers like 1.80b, 1.75a, 1.71.1. Another thing you could try is installing and using the drivers in Low DPC Latency configuration that means using C-Media Panel or XonarSwitch to change the cards settings. If you want to use Asus Audio Center, restart the PC after making the changes.
      In addition, you should check your system DPC latency if it isn’t too high.

      For the pops and cracks, I don’t know if it will work, but I have something for you to try:
      1. Download SPDIFSwitch_A and extract it
      2. Run “disable SPDIFSwitchA.exe”
      3. Run “restart card.exe”
      If it does not fix the problem you can restore the original setting by running “restore SPDIFSwitchA.exe” followed by “restart card.exe”.

      Let me know of the results.

    Hello, I’m using D2X Card on Windows10 1809, Celeron G1610 with Intel HD Graphics and 8MB Memory. The Driver version is v1.80b r3. I set ASIO Config “2ms” and run KONTAKT Player to play software piano. But When Playing, I experience popping and crack noises. Under Windows7 with UNI Xonar Driver, I haven’t experienced them. I customized Windows 10 to stop any unnecessary background apps. Do you have any solution?

    • CarvedInside16 Apr 2019 @ 04:13

      You had the same drivers and ASIO configuration when you had Windows 7?
      Try:
      1. Running Kontakt Player as administrator (right click and select “Run as administrator”)
      2. Disable Windows UAC after which restart the system.
      3. Different driver versions.
      Let me know if any of these worked.

        Thank you for your advice, CarvedInside.
        I tried 1st suggestion, and the issue has almost solved.That solution works well.
        I had the same drivers and ASIO configuration on Windows 7.
