RELEASE NOTES

Release notes 1.81a

Driver for all supported cards. Includes 1825 audio drivers for Windows 10. Unlike previous releases, the 1825 audio driver will only work in Windows 10.

Driver changes:

  • Windows 10: Updated audio driver to 1825 (built date: 22 ‎June ‎2016, made by C-Media).
  • Updated C-Media Panel.

Other notes:

  • Replaced C-Media driver uninstaller with UNi Xonar driver cleaner.

Rev. 2 changes:

  • Added support for STXII cards in Asus Audio Center, cards will be detected as STX by Asus Audio Center but feature wise almost everything should be there.

Known issues:

  • 1825 audio drivers have an issue when the audio card is uninstalled, disabled or the drivers are overwritten, resulting in a system crash. In order to avoid the uninstall system crash I've come up with a workaround  that's presented below
  • Asus Audio Center: GX button is no longer showing. It has to do with 1825 audio drivers and there may be a reason why C-Media removed it. I'm not sure if it's worth it to bring the GX on/off control back.
  • STX II:  Asus Audio Center is missing the gain 16/32 ohms for headset.
  • Windows 10: Before updating to new version, you should uninstall the v1.81a drivers, as the update process might result in BSOD (#1).

Possible issues:

  • STX II: XonarSwitch might not work. Need more feedback on this.
  • Audio playback through headphones and SPDIF at the same time isn't possible anymore. Original report. Need more confirmations.
  • DSX & probably other cards: DTS Connect with 5.1 speakers does not work. Original report. Need more confirmations.
  • There are reports that the sound quality of these audio drivers is different. RightMarkAudio tests that I've made didn't show any significant differences between v1.81a and v1.80a.
  • The 1825 audio driver may have higher DPC latency than previous drivers. Original report. The tests that I've made didn't show any difference in DPC Latency between v1.81a, v1.80a and v1.80b drivers. Maybe it has to do with the settings that are being used. My test where done with 2.0 analog output.
  • When waking system from sleep, volume from one of the speakers could be x2 louder. Original report.

How to uninstall 1825 v1.81 drivers: In order to avoid a system crash while uninstalling 1825 drivers you will need to play an audio file before proceeding with the uninstall process. Restart system after the uninstall process is done.

 

Release notes 1.80

UNi Xonar installer changes:

  • Added DPI interface scaling to the installer.
  • Added card autodetection and if the audio card is not detected it will show an error message with possible reasons for that.
  • Improved driver cleaning. It uninstalls all copies of the Xonar/C-media CMI8788 drivers that are present in the Windows driver repository. By installing drivers with "Run driver cleaning" option you won't be able to use "Roll Back Driver" option for the audio card in Device Manager.
  • Changed the driver installation procedure. Added a fail safe driver installer that should help in those cases where you were required to manually install the audio driver or install it in safe mode. Silent installation is always on and its user option has been removed. If standard driver installation gets stuck (does not finish after 100 sec) it is automatically closed. If standard driver installer fails to install the drivers then an alternate driver installer is launched. If that fails too, you will get notified by the installer that driver installation failed.

Driver changes:

  • Windows XP: Added support for other CMI8788 cards.
  • Xonar DG, DGX, DG SI: Front Panel jack detection should now work if it did with the original drivers.
  • Fixed GX not being turned off by default in "Normal" configuration for the following cards Xonar D2, D2X, DG, DGX and DG SI.

Rev. 2 changes:

  • Improved and fixed some problems with the new driver installation procedure.
  • Added different messages based on why installation failed.
  • Fixed "Front Panel Microphone" not working by default.

Rev. 3 changes:

  • Increased the delay between driver cleaning and driver installation procedures. Might help in some installation failing cases.
  • Fixed the "Warning: Windows running in Test Mode or with Disable Driver Signature Enforcement is required!" message not showing up if needed in combination with the detected audio card.

The 1.80 drivers come in two variants:

  • 1.80a "Standard"

Driver for all supported cards. Replacement for 1.75a driver. Includes 1816 audio drivers for Win XP and 1823 audio drivers for Windows Vista/7/8/8.1/10.

Driver changes:

  • Windows Vista/7/8/8.1/10: Updated audio driver to 1823 (built date: 2 Jun 2015, made by C-Media).
  • Includes updated driver installer, ASUS Audio Center and C-Media Panel.

Other notes:

  • 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.
  • Xonar STX II cards: Drivers work with STXII cards but the changing audio settings may not work with ASUS Audio Center and only with C-Media Panel. Installation on Windows Vista/7/8.1/10 x64 requires Windows running in Test Mode or with "Disable Driver Signature Enforcement" option.

Known issues:

  • STX II: Asus Audio Center does not work. You need to download this patched version and copy paste it over “C:\Program Files\UNi Xonar Audio\Customapp\”.

Possible issues:

  • Microphone stops working if running specific programs. If you run into this issue please report it in a reply to the original report. If you run into the issue you can switch to v1.75a drivers or connect the microphone to the onboard audio card microphone input.
  • WASAPI playback issues might occur with some soundcards
  • Occasionally when waking PC up from sleep the Xonar card does not output any sound.
  • Drivers might stop installing on Windows 10. Try 1.75a, 1.80b or 1.81a instead.
  • Windows 10 Creators Update: Windows would not boot after these drivers where installed. If you run into this problem you have to boot Windows in Safe Mode and remove the audio drivers. Original report. I could not reproduce the issue.
  • 1.80b "STXII"

Driver mainly for STX II and  STX II 7.1 cards. It does work for the other UNi Xonar supported cards too. Replacement for 1.75b driver. Includes STX II version 11.5 audio drivers (built date: 18 Feb 2014, made by C-Media).

Driver changes:

  • Includes updated ASIO (2.0.0.14), driver installer, ASUS Audio Center and C-Media Panel.
  • Windows XP: Drivers now work for all UNi Xonar supported cards. These were not working with 1.75b drivers.

Other notes:

Rev. 2 changes:

  • Fixed "Asus Audio Center" not working properly and getting replaced by C-Media Panel when installing with "Normal - Asus Audio Center" configuration.

Rev. 3 changes:

  • Fixed some installation issues when drivers were installed on STXII cards (like missing driver uninstall entry in Programs and Features,  incorrect C-media panel name).
  • Fixed a bug where optimal card configuration was not being applied if the drivers were installed without the "Re-enable stereo upmix" option.

Possible issues:

  • Microphone stops working occasionally or when changing audio playback settings (DS->WASAPI). If you run into this issue please report it in a reply to this comment. If you frequently run into the issue you could try v1.75a drivers if possible or connect the microphone to the onboard audio card microphone input.

Notes about Windows 10 compatibility (updated 29 May 2020)

UNi Xonar drivers v1.64 and above will work with Windows 10. There could be some issues that you could run into depending on audio settings used. Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions. You will have the same issues with corresponding versions of ASUS drivers.

Apart from driver issues, there could be issues solely from Windows 10 sound system that would be fixed with future Windows updates. There is also a small chance that some things could break with future Windows updates. Here are some solutions on how to prevent a forceful Windows 10 standard or version update.

Some of these issues also apply to other audio cards (Realtek, Creative, EVGA Nu Audio, ASUS Strix etc.) and external DACs.

> Find out which Windows version you have installed.

Windows 10 (multiple versions) notes

Possible issues and fixes:

  • Microphone not working - Check this guide. (thanks Shane)
  • Audio crashes - If you have “Dolby Atmos for Headphone” app installed you should remove it and replace it with the updated “Dolby Access” app in order to avoid audiosvr process stack overflow errors that are crashing the audio subsystem. (thanks Chris Leipold)
  • Popping and cracking sounds - If you have a AMD graphics card, try disabling AMD High Definition Audio Device from Device Manager->"Sound, video and game controllers". It's possible to try the same steps for Nvidia HD Audio Device if you have a Nvidia card. (thanks Marc)
  • BSOD's after system wakeup from sleep - Try UNi Xonar v1.71.1 driver. (thanks Kalle)
  • For systems with 1.81a drivers, the upgrading process to new Windows 10 version might result in BSOD (#1) causing the installation to fail. To avoid this problem, uninstall the v1.81a driver before upgrading.
  • The number of audio channels resets itself back to 2 or can't change to more than 2 channels(stereo) - This might be caused by having enabled one of the Spatial Sound options (Windows Sonic for Headphones, Dolby Access, Dolby Atmos for Headphones, DTS Sound Unbound). Check that Spatial Sound is Off by right-clicking on Windows Volume tray icon.
  • Sound playback echos. Issues within Windows 10 might cause the enabling of different sound settings, one of them causes sound playback echos that are more or less evident. To ensure you always get the best audio quality it might worth checking this from time to time. See Fix sound echos in Windows.
  • No system sounds. See these solutions.
  • Audio stutter in games. Open Windows Sound (right-click on Windows Volume tray icon-> Sounds or if missing type in Windows search: "change system sounds"), select Playback tab, double click your default playback device (for example Speakers ASUS Xonar Audio Device), go to Advanced tab and in the Default Format option select another sample rate setting and back to your original setting. The described windows and settings look similar to those this picture. (thanks Jean Paul).
Windows 10 version 2004 (May 2020 Update) notes

Known issues:

-

Possible issues:

Windows 10 version 1909 (November 2019 Update) notes

Known issues:

  • Higher DPC latency which may cause massive stuttering (#1). The v1909 can be uninstalled from Control Panel->Programs and Features->View Installed Updates-> select and uninstall "Feature Update to Windows 10 Version 1909 via Enablement Package (KB4517245)". To prevent v1909 update (KB4517245) to be installed again you should use Wushowhide tool (guide on how to use it) or disable Windows Update altogether for the time being.

Possible issues:

-

Windows 10 version 1903 (April 2019 Update) notes

Possible issues:

Other notes:

  • Windows Sound is no longer accessible from Windows Volume-> Sounds. If you want to control the playback devices, recording devices, Windows sounds you can open Windows Sound by typing in search: change system sounds or by going to Control Panel->Sound.
Windows 10 version 1809 (October 2018 Update) notes

Before upgrading to 1809, you should uninstall the UNi Xonar drivers especially if you have v1.81a installed, as the update process might result in BSOD (#1). As a reminder, in order to avoid a system crash while uninstalling 1825 (v1.81a) drivers you will need to play an audio file before proceeding with the uninstall process. Restart the system after the uninstall process is done.

Possible issues reported so far:

  • Crashes at boot or after walking PC from sleep or hibernation (#1)
  • Audio stops working after some time (#1)
  • Inability to change the number of audio channels to other than 2 channels when using S/PDIF output if you have Speakers disabled in Windows Sound -> Playback (#1).
  • For 1825 (v1.81a) drivers, during the installation of some Windows updates the system might get a BSOD (#1).
Windows 10 version 1803 (April 2018 Update) notes (updated 13 May 2018)

Our community member Chris Leipold reports that the wake up from sleep BSOD, settings reset and not working audio server process at startup issues that where introduced with Fall Creators Update are fixed with Red Stone 4 preview (pre 1803 release).

Possible issues and fixes:

  • Microphone not working - Check this guide. (thanks Shane)
  • Audio crashes - If you have “Dolby Atmos for Headphone” app installed you should remove it and replace it with the updated “Dolby Access” app in order to avoid audiosvr process stack overflow errors that are crashing the audio subsystem. (thanks Chris Leipold)

Possible issues reported so far:

  • Settings (Bit-depth, sample rate, number of channels) reset bug when clicking the volume after restart might still happen (#1)
  • Windows might freeze when installing Xonar drivers (#1)
  • Microphone might not work even after doing the microsoft privacy toggle fix (#1)
  • S/DPIF output might not work at least for some with Xonar DG cards (#1)
Windows 10 version 1709 (Fall Creators Update) notes (updated 13 May 2018)

Reported issues so far:

  • Drivers above 1821 v1.71 may cause BSOD when waking system from sleep (#1, #2, #3). It's unclear if it is a driver issue or a Windows issue that's triggered in specific conditions that are met when using drivers above 1821 v1.71. Since ASUS/C-media driver support is pretty much dead and most people didn't have this issue until Windows 10 Fall Creators Update, people having this issue should contact Microsoft support and submit their crash dumps.
  • Card settings are being restored after each restart. A temporarily workaround would be to save your settings as a XonarSwitch profile and apply it each reboot. Anyone affected should report the issue to Microsoft. Update 6 Feb 2018: it looks like this is fixed in insider builds >= 17074, and it will be fixed in Windows 10 version 1803. Update 8 Mar 2018: this should be fixed with KB4074588 update for version 1709.
  • Default format (bit-depth and sample rate) from Windows Volume->Playback devices and the number of audio channels resets each time the Windows Volume icon is clicked (#1, #2). Anyone affected should report the issue to Microsoft. Update 8 Mar 2018: this should be fixed with KB4074588 update. Update 13 May 2018: This issue might still happen even after installing KB4074588 (#1).
  • Possible high frequency tone when playing audio.

Standalone applications for changing settings or enhancing audio: 

1. Standalone apps pack. Based on a script made by Virus. Before running the files, close any audio source/application. Legacy, preferably use XonarSwitch and configure it with separate profiles.  Does not work correctly when used with STXII ("b") drivers. Contains:

  1. Front panel switch v3.2
  2. SampleRate switch v1.2
  3. Microphone Array Enabler v1.1 - Might be useful if you have an microphone array
  4. HDAV HDMI enabler v1.0 - This application hasn't been tested please submit feedback if it works or not. It appears it is not needed anymore.
  5. Acoustic Echo Cancellation enabler v1.0 - Useful for other Cmedia 8788 based cards that lack this setting
  6. Stereo upmix switch v1.0
  7. 7.1 virtual speaker shifter enhanced profile v1.0 - Profile created by Cu. This profile should enhance the effect of positioning in games when using Dolby Headphones and 7.1 virtual speaker shifter. Please provide feedback about this profile. Demo.
  8. Headphones ohm Amp switch v1.0  - Works only with the cards that support this.

2. Additional tweaks

  1. Disable SpeakerCompensation tweak
  2. Increase microphone volume by 3 dB tweak

3. Xonar related applications:

  1. XonarSwitch (beta) - Alternative panel to Asus Audio Center and C-Media Panel. Allows you to control various Xonar’s audio settings, define them as switchable profiles and apply them on-the-fly without having to stop the audio playback.
  2. Front Panel switch (new version) - Application that seamlessly changes between rear speakers and front panel speakers output.
  3. UNi Xonar driver cleaner - Standalone driver cleaner based on the one that's included in UNi Xonar drivers.

  6. Xonar Relay Restart - Application that will force the the Xonar relay switch to reinitialize. May be useful when there is no audio output after system boot or wake up from sleep. May be used instead of Xonar Driver Restart as it is quicker and does not affect running applications. This will cause a temporary 1 sec switch between rear and front panel outputs.
  7. Xonar-EQ - Control Xonar equalizer settings from your Android phone or tablet. By Sascha.

4. Auxiliary audio applications:

  • ASIOConfig - ASIO configuration viewer/changer that can be used when you can't access the Xonar ASIO Configuration directly. By djdecks.
  • SoundLock - Set the maximum output volume that sounds can be at. Can replace Xonar SVN in some cases (like limiting the volume of loud noises in movies). Works on Windows Vista and newer.

    ASUS ROG MAXIMUS XII HERO (Z490)+ ASUS Essence STX II, install driver (STXII 11.5 v1.80b r3) BSOD, Error: DRIVER_VERFIER_DMA_VIOLATION

    Reply

      I presume you have Windows 10, but which version? Did this start as soon as you've upgraded to the Z490 motherboard? Did you migrated the OS from the previous system or did a new install?

      • HSM0601 Jun 2020 @ 07:05

        Windows 10 1909 & 2004 Have tried ,That's right, there was a problem after upgrading to z490 , Are new installations , The situation is the same bsod .

          Have you tried installing the drivers with Windows in safe mode? What about manually installing the driver according to Possible Solution 1 this page? You should also try a different driver version like v1.80a, see if that works by any chance.

          • HSM0601 Jun 2020 @ 16:52

            I tried the installation again after trying BSOD.The driver has a Code 52 driver error.
            I try to enter Disable driver signing mode. The result is bsod before loading the desktop, BSOD : DRIVER_VERFIER_DMA_VIOLATION

            I just tried to install in safe mode. Restart the device, Code52 appears, I try to enter the "disable driver signature" mode, still BSOD DRIVER_VERIFIER_DMA_VIOLATION.

            I tried to install the original ASUS driver, and it was still BSOD: DRIVER_VERIFIER_DMA_VIOLATION.
            I have feedback related questions to ASUS official customer service, but I don't think there will be any response...

              I think the BSOD issue you have is because of the motherboard. ASUS might be able to fix it with BIOS update but whether they care or not to investigate and fix it remains to be seen.

              There are some other things you could try, maybe get it working but if I am to spend more of my time on this I need to receive a money compensation from you. If you are interested let me know. If you've previously sent me a donation, send me an e-mail from that e-mail address you used for payment.

      Found a possible workaround for Asus Essence STX 2 and AM4 reboot/BSOD. For those who are f***** with BSOD. For my X570 it works if I pre install http://www.asio4all.org/ before you install the Essence driver it seems to work well for me. For now stable!!!

    Hey there! Got a Xonar DX, but since upgrading to Win10 2004 the drivers seem to have been replaced with Microsoft Audio Endpoint drivers 10.0.19041.1. When run the installer for Xonar it installs fine, but nothing changes when looking at the devices in device manager. If I select the INF manually, it says it doesn't contain compatible software driver for your device. Anyone having this issue? Tried 1.80 and 1.81.

      1. In Device Manager, does the card show up as ASUS Xonar DX or as Microsoft Audio Endpoint?
      2. In Device Manager, double click on ASUS Xonar DX or Microsoft Audio Endpoint device, go to Details tab, select "Hardware Ids" in the Propriety field, copy the top hardware id and provide it here.
      3. Is the card properly detected as a Xonar DX in the UNi Xonar installer?
      4. So just prior to upgrading to Windows 10 version 2004 the card worked properly?
      5. Just to clarify, this was an upgrade for a prior Windows 10 version and not a new installation?

        Thanks for your response. The card does show up as ASUS Xonar DX. I guess I was just thrown off by the fact that in the driver section of the properties it lists the Microsoft Audio Endpoint rather than saying something like ASUS or UNi Xonar etc. I was under the impression that the UNi Xonar driver version reflected there in the past. It was definitely weird because I had some audio issues following the upgrade - not a new installation - went from 1909 to 2004. I kept having cracking sounds and random other stuff happening that I didn't experience before. However, after running the driver cleaner and reinstalling and reapplying my settings it does now seem to work properly. Sorry for the rushed call for help!

      I have Xonar DX and it works fine on Win10 2004. Didn't need to re-install the driver after updated from 1903 to 2004. I'm using v1.71.1, never tried any other version.

    Hello! I am running into a rather annoying issue with my Xonar Essence STX II. I tried finding information on it, but was only able to find one article that describes this issue: https://www.stereophile.com/content/asus-xonar-essence-ststx-soundcards-follow-september-2010
    Basically, when outputting through coax (selected through the tick-box in the asus driver panel), whenever audio playback is interrupted when the signal is not 0, there will be a persistent DC offset at the value the last played audio sample was at volume wise and channel-independent, and it persists until another audio source is started (aka, simple pausing and resuming playback of music, skipping through the playback bar, closing a browser while a video is playing and starting playback of music or a game etc., you get what I mean, it is happening ALL the time) and will cause potentially heavy popping sounds depending on where playback was interrupted. Despite the article saying that the problem is not pathological and does not seem to translate to the analog outputs of whatever external DACs they were using, it is very well an issue on my end. I am using a Schiit Modi Multibit and a Magni 3+ as my DAC/AMP combo, OS is Windows 10.
    My question is, is this something that can even be fixed by using a different driver like the UNi Xonar drivers? Is this a known issue or has it been addressed by the UNi drivers already? Is there anything I can do to prevent this aside from not using the coax output or using a different DAC (which I do not have)?
    I appreciate any input!

    Hey there!

    I just installed the STX II in my Ryzen System. Disabled onboard Sound,Uninstalled Nvidia Audio Drivers. Installation went fine but I have some serious Audio Issues.
    I'm using a Beyerdynamic DT 770 Pro 250 Ohm. If I set the Gain to 64-300 Ohms i get cracking which sounds like "overdrive". Like upping the Volume to max and all the sounds get distorted. I hope you know what i mean.
    But if i set the Gain to 16 Ohms that Problem is gone. But then I'm getting a High pitched Sound all the time like coil whine.
    Any Idea whats causing that? I'm almost at the point of sending it back and using my Onboard Sound.

    Hi,

    Since the 2004 install these have not worked for me. Everything was fine on 1806. I did an in-place upgrade to 2004 and things seemed to function OK. I got some new RAM and installed and started encountering errors in games, new Edge trying to play YouTube would crash even when not using headphones through my STX II, and even had some completely random BSODs seemingly coming from either NVidia or wdf01000.sys. After scrutinizing the hell my new RAM, the system was generally unreliable so I formatted. Upon a fresh install, this time 2004, the system was fine up until I tried to install these drivers. The system would quickly become extremely slow and eventually lock up. Forcing a reboot wouldn't even work. Each time I had to rely on Windows to kick me to the advanced options screen, and I had restore back to a restore point.

    I tried versions v1.81a r2, v1.80a r3, v1.75a r3, and v1.71.1. I'm willing to be a limited guinea pig of sorts so let me know if you want any particular logs. I would be willing to send them to an email but don't want to make anything available here in a thread.

      Hi.
      1. You mistyped or misremembered the previous Windows version where it worked fine. If you can clarify which version was it.
      2. Have you tested your new memory with Windows Memory test or with some other memory testing program?
      3. What system do you have (motherboard, CPU and video card)?
      4. Have you tried installing the UNi Xonar drivers with "Low DPC Latency" configuration? What about with "Normal" configuration?

      BTW Thank you for the donation. If you wouldn't have done so, I would be asking that you do, because I'm increasingly tired of offering my services completely for free.

        1. Correct. That should have been 1809.
        2. I used the Windows Memory Diagnostic utility on basic first then the enhanced/extended configuration.
        3. I have a Taichi X370 mobo, Ryzen 2700X CPU, and an RTX 2070 GPU. I understand the official support for X370 isn't there but like I said it was working great before. I hope Microsoft didn't kill whatever method you have of giving broader support.
        4. No, I didn't as the DPC tool I used reported ready for real-time apps so I didn't see a pressing need for it. I will try that. I tried normal install and the C-Media version.

        As for the donation, for sure. I'm more about the annoyance of ads than not paying for software I use, but I get they're a reality and more often a relenting than something webmasters actually want on their sites. Best of luck.

        LE: I used the DSP DPC option with the v1.80b r3 version since it comes with a signed driver. Works great, thank you! Question though: the other media controlling app let me change the gain group since I have high impedance headphones. I don't see a similar option in the DSP DPC install with C-Media. Is there a way I can change this option? The sound coming through is a bit muted so I have to turn it up more than usual.

        • CarvedInside25 Jun 2020 @ 00:43

          Hmm... The thing is, "C-Media Panel" configuration that you've previously tried should have behaved the same as "Low DPC Latency" configuration in this regard as they both lack HsMgr(GX) processes which could cause some conflicts with other software. Let's see if it continues to work or something else is or was going on.

          Regarding the compatibility between your ASRock Taichi X370 motherboard and the STX II card, did you had to do anything to make it work initially, like changing PCIe Gen speed or the PCIe slot? In which PCIe slot the STX II is plugged? Regarding the issues you had, have you updated the motherboard BIOS when you've upgraded the RAM and the issues started?

          For setting headphones gain, either launch ASUS Audio Center and set it there or what I would recommend is to use XonarSwitch.

            The only oddity I noticed on my initial install was that the installer didn't like that it was running in a Hyper-V environment. Windows automatically creates one when you use things like the Virtual Machine Platform or Application Guard. I had to use bcedit to force disable it, do the install with driver signature checking disabled, and then I could reboot and turn it back on and everything was normal. The only intermittent oddity from there out was that sometimes my headphones would squelch at max volume (really f-ing loud, btw) and my machine would lock up. It happened maybe a couple times and didn't seem to follow a pattern.

            I flashed my BIOS to latest several months ago so there hasn't been a correlation between new RAM or whatnot. Almost as a rule I don't do major upgrades in tandem. Do you think it'd be worth while to try the normal install with the signed driver?

              For now I would keep the drivers with "Low DPC Latency" configuration, see how it goes for a week or so, then you could try the "Normal" configuration again.
              Because you mention you had that loud noise and system lock issues, it means it was not exactly fine before. These issues might have the same cause, whether it's because of running in the Hyper-V environment or because of the Ryzen AM4 platform. Let me know how it goes now and if you find anything else.

      If you can't find one then they most likely don't make them anymore. Honestly, this isn't a question for this page and instead you should have contacted ASUS support.

    Using Essence STX and W10 2004 broke digital out/SPDIF for me. With 1909 I could output equalized sound from Essence control panel to my BT transmitter with TOSLINK, but now only pass-through works, which means no EQ settings for optical digital out.

      Which drivers have your tried? I suggest trying with different driver version see if with any of them it works (1.71.1, 1.75a, 1.80b, 1.81a).

        This was with 1.81A, but I got around the EQ problem by using APO Equalizer which seems to only use 0.2% of CPU. There seems to be a lot of problems with S/PDIF being broken on version 2004 in general, not just with these sound cards.

          Thank you for sharing the link.

          When you said "only pass-through works" did you meant that only "S/PDIF Pass-through Device (ASUS Xonar...)" output device is working or you meant that the standard S/PDIF output that you enable in the Xonar audio panel works but the sound does not have the EQ settings applied?

            I only get optical audio out of the when ticking SPDIF Out and selecting PCM in the Xonar Audio Center, but that does not result in EQ or other settings in the control panel to affect the output. From what I recall in 1909, there were also PCM options in the Windows sound control panel for SPDIF which gave me equalized audio from the Xonar control panel, but that Windows setting does not seem to exist in version 2004.

    I recently put this card in my current PC and installed latest UNi drivers on Windows 10 2004. I installed UNi driver with low DPC latency, but I'm surprised to find that setting WASAPI exclusive latency lower than 10ms in Jriver output results in garbled audio. I have a USB ODAC working fine at 5ms, so it's not my PC. Is this normal? Are there some firmware PCI settings I should look into?

    • CarvedInside22 Jun 2020 @ 04:44

      1. Which card?
      2. If you try with the onboard audio card, how that goes?
      3. What USB DAC do you have?
      4. When you say the USB DAC working fine at 5ms, is if you try it now with the current Windows version and other configuration?
      5. What motherboard and CPU do you have?

      I don't know if this is normal, I have never tried this.

    I will be replacing my Xonar D2X with an Essence STX II 7.1.

    Should I use my existing Unified driver (1.81a r2) or uninstall that and use the official Asus driver which is dated December 2019? My #1 priority is audio quality. I don't use any of the Dolby/surround features etc.

    • CarvedInside24 Jun 2020 @ 03:42

      You will have to install the drivers again even if you chose v1.81a drivers. I think you should probably go with 1.80b, if you have any problems try the other ones.
      About those ASUS drivers, ASUS just removed the beta tag from previous STX II 2015 driver package. Those have the same audio driver as UNi Xonar 1.80b drivers.

          Yes it's working perfectly, better than with windows 10 IMHO.
          IT can work directly with pulse audio or you can use it with pure alsa setup with a .asoundrc configured with dmix/dnoop.
          You can choose impedance level and switch speaker/headset/frontpanel too.
          I personnaly use qasmixer to access all features.

    Hi.
    Firstly i give you my specs:
    Windows 10 home x64, os version: 1909, os compilation: 18363.900
    Sound card: ASUS Xonar D2/PM/A, sound card driver: UNi Xonar W10 1825 v1.81a r2, main board: MSI Z270 pc mate

    Additionally i have software platform by Waves (Waves SoundGrid). It's related to its famous VST plugins bundle pack. Waves software never causes problems in my case, probably it's another cause.

    I want to connect turntable in a simpliest way (only through mixer and 2-cinch-mini jack cable).

    2 months ago I've installed above-mentioned windows 10 and now my Line In source via sound card doesn't work.:( In my win sound preferences appears "In Line input is currently unavaliable". My sound card setup contains only two sources:
    - speakers: Asus Xonar D2 Audio Device
    - line in: Asus Xonar D2 Audio Device

    I've tried reinstall original drivers and obviously it didn't work.
    What's interesting, previously, on original ASUS drivers, at least i can hear sound from turntable (but i can't record it).
    After installation Your drivers, everything just shut (but i think pc sound is slightly better :).

    Does anyone has it and can help? I guess you have some advice.
    Best regards.
