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.
  • High DPC latency reported by LatencyMon. Original report. Need more confirmations.

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.

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.
  • 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.

 

Release notes 1.75

UNi Xonar Installer changes:

  • Various changes and improvements done to the UNi Xonar installer.
  • Added warning message if installing the drivers would require Test Mode.
  • XonarSwitch is now automatically closed before installing the audio drivers.
  • Improved “Apply addons” function. Included .inf files from the drivers can now be dynamically altered. Documentation can be read here. Applying new 1.75 compatible versions of addons (like DHT4) will display the proper audio driver version now and users could now choose which addons they want to install once these are added to the Uni Xonar installer location.

Rev. 3 changes:

  • Fixed GX is not being turned off by default in Normal configuration for the following cards Xonar D2, D2X, DG, DGX, DG SI.

Rev.2 changes:

  • Fixed ASUS and C-Media Panels not working in Win XP.
  • Includes updated driver installer and C-Media Panel.

Known issues:

  • The installer is showing “Warning: Test mode to be enabled!” message by mistake if Xonar Xense selected as card.

Possible issues:

  • Missing Dolby Pro-Logic IIx options from C-media Panel. If you have this issue, you can use the “C-media Panel v1.62” installer addon or install v1.72 drivers.
  • 1.75b “STXII”

Driver mainly for STX II and  STX II 7.1 cards. It also works with UNi Xonar previously supported cards.

Rev.2 changes:

  • Fixed issue where installer did not apply the correct audio settings (e.g. to fix surround echo). Anyone who installed the previous 1.75b drivers should install the 1.75b rev.2.

Driver changes:

  • Includes updated ASIO (2.0.0.13) , ASUS Audio Center and C-Media Panel.
  • Includes STX II version 11.5  audio drivers (created on 18 Feb 2014).

  • These drivers do not work for the other Xonar cards on Windows XP.

Known issues:

  • ASIO in 64 bit mode does not work. The cause of this issue is the 64 bit asio  dll file from the original STXII drivers.

UNi Xonar Installer changes:

  • Fixed some issues with Driver cleaning module
  • Improved and fixed some potential issues with UNi Xonar Installer

Known issues :

  • In some cases,  WASAPI exclusive playback is interrupted by playback from other audio applications. More details here.  Fix: If you don’t use S/PDIF, disable Digital Output from Control panel->Sound. It’s confirmed that the audio drivers included in 1.70 don’t have this issue.
  • Win Vista/7/8, there are reports that you cannot play sound through S/PDIF and headphones at the same time.

Notes about Windows 10 compatibility (updated 25 Jan 2017)

UNi Xonar drivers above v1.64 will work in Windows 10 but since the audio drivers are not yet made specifically for 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.

  • Update 30 Aug 2016: Thank you for the feedback so far. Based on the feedback received there shouldn’t be any problems installing the drivers on Windows 10 Anniversary Update (build 1607) whether it’s an upgrade or a new installation. One user reported that audio card was recognized only when installing the drivers when booting with Disable Driver Signature Enforcement option. Apart from drivers installation aspect, this new Windows build brings new problems for some users like the following reported ones: crackling or loud popping sound in the speakers, audio card not being detected sometimes or disappearing in Windows and 5.1 analog not working. For those of you who started having problems only after the Anniversary build upgrade you could roll back to a previous Windows 10 build (#1, #2). If that is not possible you can download a older Windows 10 build from here and install it without a internet connection present. To prevent upgrading to build 1607 you need to disable “Windows Update” service from Control Panel->Administrative Tools->Services.
  • Update 3 Aug 2016: Microsoft made changes to driver signature policy with the Windows 10 Anniversary Update (1607) that could make the Xonar drivers not working/installing anymore. There are some exceptions from this driver signature enforcement. At the moment it’s unclear to me if installing the drivers in Test Mode or with Disable Driver Signature Enforcement still works. I’m interested in hearing you experience under this discussion thread.
  • Update 28 Nov 2015: The Windows 10 Threshold 2 update does not seem to fix many of the sound issues that where present so far and it may introduce new ones. In my opinion Windows 10 is a very buggy OS, the only things working fine are the spying of its users(#1, #2) and the periodic removal of user preferences and programs(#1, #2, #3, #4).
  • Update 19 Oct 2015: The audio fixes from Insider Previews >= 10547 will probably be included in the upcoming “Threshold 2” update that will be released around November 2015.
  • Update 1 Oct 2015: The Windows 10 development team is fixing some audio issues with Windows 10. The fixes where made available for testing starting with Windows 10 Insider Preview build 10547.

100% compatible drivers when?

Because of the very slow development of the audio drivers by C-Media and the long time it takes for C-Media partners (ASUS and HTOmega) to release the new drivers it may take a while before we have a 100% compatible driver for Windows 10.  If we are lucky we will have new audio drivers in 2-3 months after Windows 10 RTM launch. As soon as new audio drivers became available I will release a new UNi Xonar drivers package.

  • Update 25 Jan 2017: 1825 audio drivers for Windows 10 are available. These are the first audio drivers that only work on Windows 10. Hopefully they will perform better than those that supported also Windows 7 and Windows 8.1.
  • Update 01 Oct 2015: 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.

About Chrome stutter issues on sites like YouTube. (27 Aug 2015)

  • Update 27 Aug 2015: The stutter issues on youtube are  fixed with the latest Chrome build released on 20 Aug 2015 (v 44.0.2403.157). Reports indicate that stutter issues are still happening for videos on other websites (eg. daily motion, facebook, instagram).
  • Update 7 Aug 2015: After some testing and some reading it seems that the stuttering issues are not related to the UNi Xonar drivers. I’ve got the same behavior with Realtek’s onboard audio and from what it looked liked. My guess the issue is caused either by Windows 10 or Chrome.

There is a Chromium issue opened here.

Here are some things you could try:

  • Change Chrome audio buffer size.
  • Change/keep sample rate to 44.1 kHz both in the audio panel and Windows Volume->Playback devices->(…) Audio Device Proprieties -> Advanced -> Default Format.
  • Change sample rates back and forward a couple of times.

    Hi, since I’ve installed Win 10, the Fixsoundloop.bat doesn’t work anymore. It usually restarted my XonarD1 and fixed problems like the name says, or if the right or left speaker was louder/quieter than the other. Now it only displays the message:

    Has the PCI number changed so this line from the .bat isn’t applicable anymore? “@devcon enable PCI\VEN_13F6”
    Any help would be appreciated.

    I was seeking through a YouTube video when suddenly continuous max-volume screeching glitchnoise was pounding through my speakers, way past the system volume level I was at. I’m wondering if there’s any precedent of these drivers fixing this specific issue. I think I’m going to ditch the card, I can’t risk damaging my equipment or my hearing testing such an atrocious bug. These cards are dangerous.

      I had the same problem with Xonar DX, now i’m using updated official drivers and I think that the problem is fixed.

      Had the same problem when playing a video in Chrome while wearing headphones plugged into a Xonar Xense. Audio was maxed out and screeching in the left channel only. Happened again a week later with speakers. I doubt ASUS will ever provide fixed drivers for Windows 10 so I think I’m done with their cards. Maybe it’s time to get an external DAC and amp.

        Same problem with my DGX here! I only recently noticed this since I had cheap headphones before with a very narrow frequency range. But with my bro’s AKG K240’s I heard screeching in the left earcup, same thing with my new ATH-M50X but they have bloated bass instead of screeching, specifically in the left earcup. So I’m probably gonna get a FiiO E10K, I saved a whole year for these headphones, I don’t wanna damage them.

    I want to report this problem “Possible issues:
    Occasional Left or Right speaker imbalance or volume drop. This is a different issue that the L or R volume drop issue that some people have regardless of the drivers they install. There are 2 user reports for this issue.” too. My drivers are 1.75a and I run Windows 10, my sound card is Asus Xonar DX. I tried everything in mind but it didn’t work to re-balance the volume difference (like restarting the audio service, trobleshooting the audio hw/sw etc). I need to restart the PC to solve. It happened 2 times for now and always on my left speaker ( the main one ).

      Thanks for sharing. At the moment ASUS seems to not release any new drivers, just changing the supported Windows version in the installer from their old Win8.1 drivers. So there might not be any new audio drivers in September or October either.

      Ouch. October for my D1… And the crackling problem doesn’t seem to go away. (There were numerous windows updates)

      No planned update for the D2X, but planned update for the DX? What are they smoking?

    My 6 August post seems to have been lost amongst the noise, so I thought I’d re-post it in the hope someone can help me…

    I have an Asus D2X card on an MSI motherboard, running Win7Pro64. The Asus S/PDIF output connects to an external surround receiver with in-built DTS/DD decoders. I’m trying to get DTS pass-through (from DTS-encoded FLAC music files), but all I get is silence. I started with the default Asus-supplied driver, and now have installed this UNi Xonar 1816/1822 v1.75a r2 driver, but they both do the same thing…

    If I go into the Windows Control Panel/Sounds, and Properties for the card (set for ‘Digital Output’), I can select DTS and Test, and the receiver displays ‘DTS’ and correctly plays the test sounds through my four speakers. But if I play a DTS audio track (and I’ve tried several different players), I just get silence from the receiver (and no ‘DTS’ indication). Stereo tracks play OK through the S/PDIF connection.

    Can anyone help me get DTS pass-through working?

    Thanks, Daniel

    I’ve just purchased a STX (not the STX II which is far too expensive where I live). It is replacing my trusty but aging D2X which has done sterling service for four years.

    I’m running Windows 10 Pro. Before installing the STX I in addition to uninstalling the old drivers I also did a thorough registry and file clean up using CCleaner and Driver Fusion. Once the card was in the PC I installed the 1.75a-r2 drivers (low latency option). They installed with no issues after a reboot. I’m happy to report everything works fine (also using Xonar Switch. So a big thanks to those who contributed to the development of the drivers and Xonar Switch.

    Hi. I have a strange issue. It’s not a deal breaker, but if possible, I’d like to know how to fix it.

    After I install the latest Uni Xonar drivers for D2X card on Win 7 x64 and I restart, I get the blue CMedia Panel icon in the notification area. But on the next restart, the icon disappears. From the start menu, I found out its location is C:\Windows\System32\CmiCnfgP.cpl and I can make a desktop shortcut that way and use it.

    Now, to be completely honest, this started happening after a round of windows updates followed by disabling some windows services.

    In any case, can you tell me if a Windows service is required for the notification area icon to appear every time? Or is it something else, like a scheduled task?

      Hi. Which panel configuration have you selected when you installed the Uni Xonar drivers drivers?
      There is no service related to autostarting C-Media Panel, it is a startup entry which can be controlled from Run->msconfig->Startup tab->”CmiCnfg Dynamic Link Library” entry.

      You can either reinstall the drivers with C-Media Panel panel configuration, re-enable from msconfig or add a C-media Panel shortcut to Start->Programs->Startup.

    Hello,

    Is it possible to change the settings available in Xonar Control Panel without having it installed? I have only the drivers installed and am wondering if it would be possible to do so and if how?

      Hi. For some settings you could use the Standalone applications that are available in the download section of the post above. You could change settings in the registry but you have to know which key does what and I don’t have a manual for that. For the registry settings location see FAQ Q&A5.1.

      I’m curios, why do you not use one of the Xonar cards control panels (Asus Audio Center, C-media Panel or Xonar switch) to change the cards settings?

    I am on Windows 10 64 bit using Asus Xonar DG (just purchased a few days ago), installed the latest driver update from this site. Everything was working fine for a few days, while I was playing LoL, the sound suddenly got distorted where I can only hear a faint background music, with no foreground vocals. This problem is happening within Chrome, VLC, LoL, basically from any audio source.I tried to install the official driver from Asus to see if it would work, but it says it’s incompatible with my OS. I will try to install the previous unified driver and see if it will work. But I am thinking that it may be a hardware issue now. Anyone experiencing similar issues?

      Disable GX if you didn’t already. If that does not fix things, you could try installing the drivers with Low DPC Latency option.

      I experienced that same issue today with World of Warships. The thing is, I wasn’t using these drivers, I am using the onboard Realtek as my new motherboard doesn’t have a PCI slot…

      I believe it is a problem with Windows 10, not the drivers or hardware themselves.

      Hi,
      These are actually the same audio drivers (1822) that I use in UNi Xonar v1.72 and v1.75. So they are nothing new. But thanks for sharing.
      May I ask where did you get these?

    Windows 7 64 bit // Xonar DX // Tried different drivers: 1.72 and 1.75b – Asus Audio Center available only afteri installing the driver – it’s impossible to find it installed anywhere, while running – the app is linking to a process “rundll32”. Same issue with C-Panel. HOW DO I LOAD THE SOUND CONTROL SOFTWARE ON STARTUP. as it’s been written in the comments previously – msconfig -> startup etc. i can’t add any additional processes there (or don’t know how). this is seriously killing me and eating my time.

    [comment merge]
    I have to reinstal driver every time i want to switch from speakers to headphones and vice verce….etc…. thats because the Xonar Audio Center or that C-panel doesn’t load after you restart the PC. and there are no shortcuts to the application.

    I experience very short sound lag/spike (like ~0.2 sec) using WASAPI event/push mode in foobar2000. I checked every possible buffer length (50-10000 ms) and I can still hear this distortion in random parts of the songs. Normal DirectSound output works well. I tried ASUS official, UNi low-latency and normal UNi drivers and problem appears every time.

    UNi Xonar Drivers 1.75b, Xonar Essence STX II, Windows 10 x64, Windows Sounds – disabled, Lower sound when communication – disabled
