1. I get system crashes (BSODs), I get audio panel crashes, audio panel does not launch, some settings are missing or some settings do not work anymore. What can I do? (updated 4.10.2015)

Things to try:

  1. First make sure you have GX (Xear3D) is disabled in the audio panel.
  2. Try reinstalling (uninstall and install) of the audio drivers with the “Run driver cleaning before install” option selected in the UNi Xonar installer. Optionally you could do a extended driver clean (see below) before installing the drivers again.
  3. If you only got these issues after you’ve installed newer UNi Xonar drivers and the suggestions above did not work then try with older driver releases. You may have to go back to the drivers you previously had installed. If previous drivers are working please write a comment describing the situation in the main UNi Xonar page.

Extended driver cleaning guide:

  1. Uninstall any Xonar drivers (search for Asus Xonar and/or UNi Xonar)  and restart after that.
  2. Download and run “UNi Xonar driver cleaner.exe“.
  3. You have to download and install Driver Sweeper or its successor, Driver Fusion. Launch it -> select ASUS Sound -> press Analyse -> press Clean -> Restart.
  4. Install UNi Xonar drivers.

2. ASIO playback doesn’t work with some applications and it worked with the original drivers.

You need to reconfigure the ASIO device output in the preferences of the audio application you are using.

 


3. Using UNi Xonar with C-Media Audio Center and can’t set the headphones gain, switch output to front panel or change sample rate? (updated)

The easiest way is to launch the Asus Xonar Audio Center (Start->All Programs -> Uni Xonar Driver) and change it from there.

Alternatively,  you can download the Standalone Apps package listed in the main UNi Xonar Page, and use the applications you want to change the settings. This is recommended so that you don’t get a increase in DPC latency or other system interferences with the launch of Asus Xonar Audio Center.

 


4. How to enable stereo upmix (2.0 channels signal to 5.1/7.1 speakers)? (updated 19.07.2014)

There are two ways:

a. Through the drivers

Check “Re-enable stereo upmix to 4,5.1 and 7.1” option in the UNi Xonar driver installer. This option works slightly different in Win Vista/7/8 than how it works in Win XP:

  • On Windows XP if you set the output to 6 channels you always get the upmix (with stereo upmix option checked).
  • On Win Vista/7/8 it works if you set this settings in Asus/Cmedia Audio Panel: set audio channels to 2  and analog output to 5.1 speakers. Caution: it won’t work if you set audio channels to 6 and analog out to 5.1. By selecting this your Windows and other applications will output the sound from 2.0 format to 5.1 speakers and not 5.1 format to 5.1 speakers.

An alternative for enabling stereo upmix is to enable Dolby Pro Logic IIx and this should upmix the the 2 channel signal to all the speakers. Enabling GX in order to have a working stereo upmix in Win Vista/7/8 is not recommend because of the crashes and issues that arise because of GX (see Q&A 11).

b. Through players settings

Possibly a better way to enable stereo upmix is to enable it on a case by case basis through your Audio/Video player settings.  Some players need a dedicated plugin in order to do this (like Channel Mixer for foobar2000). In this case the Asus/C-Media Panel settings need to be 6 channels and 5.1 speakers or so, depending on your audio system.


5. How to save your current settings? How to manually edit the Xonar settings in the registry? (updated 02.03.2012)

5.1. Finding settings path in the registry

1) Press Start -> Run or Search field and type regedit
2) navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet in the left pane
3) Press CTRL+F and type BassBasedBLevel and click find, this will jump you to xonar registry settings path. This “folder” (0005\Settings or any other number)  is where the Xonar settings are stored.

5.2 Exporting

Right click on Settings “folder” and click export. Type a name and click Save.

5.3 Edit 

Before importing, check your current registry path for the Audio card  settings, as they might be not stored in “0005”(or any other name) like it was when you saved the registry. If this is different, you need to edit the previously exported reg file (right click->edit) , and replace the old path with the new one (example: …005settings to …011settings). Save the file.

5.4 Importing

Double click on the saved registry file and press “yes” when prompted. Note that you need to restart your PC or disable and enable your Xonar card in Device Manager in order for settings to apply.

TIP: By exporting and importing the Xonar registry settings, you can save your settings before uninstalling the drivers and installing a newer version. In this case, you have to import it after you’ve installed the driver. In order for them to apply you need to either restart your PC or disable/enable Xonar Card from Device Manager.


6. What is Panorama Enhancement in Dolby Pro Logic settings?

HunterZ: Panorama effects usually cause the sound to “wrap” around to the surround speakers, creating a larger and/or more immersive stereo stage. A lot of Dolby ProLogic II Music decoders have a similar effect when decoding in music mode.


7. Does sample rate automatically change  with ASIO 2.0 depending on audio files sample rate? 

Yes. You should usually hear a pop when you change to music with different sample rate.


8. How to add/change sound delay to the rear speakers & center?

  1. Navigate to the settings path ( see 5.1. Finding settings path in the registry paragraph)
  2. You have the following variables for adjusting delay LsRsDelay , CenterDelay , LbRbDelay – for side/rear , center , rear in 7.1 . If you don’t have them you need to create them, Right-click on black space -> New ->Binary value.
  3. Double click on the variable you want to edit, and instead of 000000 type 050000.This should add a delay of 5 seconds to the channel you are editing. The settings are in hexadecimal form. Some examples: 9 ms is “09 00 00 00”, 10 ms is “0a 00 00 00” , 11 ms is “0b 00 00 00”, 15 ms is “0f 00 00 00” , 20 ms is “14 00 00 00”
  4. For new settings to apply you either need to restart, or disable and re-enable the Xonar card from Device Manager

9. What are best settings to achieve best audio quality, performance and functionality from my (Xonar) card?  (updated 06.03.2014)

In ASUS/C-media/XonarSwitch Control Panels :

  • Keep Sample Rate at 44.1 kHz , this is generally valid for most media (games, movies, music), while video DVDs use 48 kHz. Increasing Sample Rate without having a source that’s sampled at a higher rate won’t improve sound quality, in fact it will degrade it.
  • Select Audio Channel/System input (present only in Win Vista/7/8) and Analog Out/System Output settings based on the number of speakers that you have. For a 5.1 audio system select Audio Channel to 6 and Analog Out to 5.1. For a 2.1 audio system, select  Audio Channel to 2 and Analog Out to 2.  By default, selecting more channels than the number of speakers you have connected won’t enable you to hear more sounds or hear the footsteps and positioning of enemies better in games.
    • If you wish to emulate 8 channels surround on a 2 channel headphones you need to enable “Dolby Headphones” and “7.1 virtual speaker shifter” after setting the number of channels to 8 and analog output to “Headphones”.
  • Keep GX (Xear 3D) disabled. GX is responsible with emulating EAX effects in some games, but it’s know to cause crashes and audio loops in games and other applications while this is enabled.
  • Be careful with what you enable. The effects will increase the DPC latency which in turn could cause other problems like audio/video desynchronization or slow network/internet speed, and they also change the sound not always in a good way, you might like it for your music but it might harm the audio positioning in games.

In Windows:

  • Windows Vista/7/8/10: Setting the Windows audio playback to 24 bit might improve audio quality. Right click on volume icon in tray, select Playback devices, double click on (Speakers) Xonar card , go to Advanced tab and in the Default format entry select 24 bit 44100 Hz (studio quality) as shown in this picture. While you can change this to 32 bit, this probably isn’t needed. Many Xonar cards only support up to 24 bit and even if this wouldn’t be the case, setting Windows audio playback to 32 bit won’t usually have a improvement in quality compared to 24 bit.  You can find detailed information on audio bit-depth here.
  • Windows XP only: Don’t increase the Windows Audio Volume to 100%, instead set it to 80-90% max in order to avoid dynamic volume issue. Issue regarding setting volume to 100% is detailed here.

In audio/video applications:

  • Enable the  audio output/playback to 24 bit instead of 16bit, as this  might improve audio quality. This setting is application specific  so you will have to search for it in application preferences/options. For example, in Winamp the setting is located in Preferences->Playback->Allow 24bit. If you have Windows Vista,7 or 8 then you have to enable 24 bit output in Windows as well.
  • If you use ASIO as playback output, recommended settings would be Bit-Depth:24-bit and Latency: 10 ms or above.
  • Windows Vista/7/8/10 only: Set each application volume at 80-90% in order to avoid dynamic volume issue. Issue regarding setting volume to 100% is detailed here.

In games:

  • In game Options -> Sound Quality set Medium or High depending on the importance of sound quality in that particular game. Setting this to High might cause to much strain on your CPU and this in turn will affect the FPS of that particular game.
  • In-game options: make sure you have properly detected or set the number of speakers you currently have connected.

10. Audio in Flash player (like from videos in youtube.com) is upmixed to 5.1 although stereo upmix is disabled. Why is that? (updated 19.07.2014)

It’s a bug in the Adobe Flash Player (info1info2) which might not be fixed by Adobe any time soon.

There is a user made fix but it might not work with newer flash versions and it does not seem to work on Win 8. You can find the fix here. Follow the instructions in the readme.txt file.

If you are mostly viewing clips on youtube.com, a possible workaround would be to watch the videos in HTML5 video player instead of Flash player. To do so, go to youtube html5 page and turn “HTML5 Video” on.


11. Why is GX (EAX emulation) bad?

In most of the cases it doesn’t even work and the worse part is that while having GX enabled any audio application that you use is prone to crashes or makes your whole system crash (BSOD).

ASUS/C-media emulation of EAX capabilities is disastrous and should have never been released in this state and marketed as a feature. If you want a reason to sue Asus this is it.

GX is labeled as Xear3D in C-Media Audio Panel.


12. My antivirus says that the UNi Xonar driver package has a virus or trojan.

If you’ve downloaded the drivers from the official links then the virus warning is a false positive. Possible causes are the packaging of the drivers or the presence of driver cleaner in the UNi Xonar installer which deletes the Xonar driver files from Windows folder.

While it’s highly unlikely that UNi Xonar driver packages would be compromised and be infected with viruses, if you really want to be sure then you can submit the driver package for analysis to www.virustotal.com for a wider analysis.

Furthermore, UNi Xonar driver installer (again from the official links)  does not contain any adware, spyware or PUP (Potentially Unwanted Program).

In such cases where your antivirus blocks the installation or the download of UNi Xonar drivers you need to either configure the antivirus to allow that action or temporary pause antivirus protection.


13. When new drivers are going to be released?

There is no time frame. UNi Xonar driver releases depend on one or two factors:

1. When new original audio drivers are made available (eg: when ASUS releases a new set of drivers for any of their Xonar cards or when ASUS releases a new Xonar card).

2. When in my research for fixes or improvements I find something that can be implemented (eg: Stereo Upmix issue fix or the Rear and Center channel delays fix).


14. Is there a Linux or Mac version of UNi Xonar drivers?

No Linux or Mac version. UNi Xonar drivers are based on Xonar original drivers for Windows.


15. I’m receiving “Can’t find any device” message and I can’t change any of the Xonar card settings.

This error is generated by Asus Audio Center. Other drivers, security programs or changes made by Windows updates might prevent Asus Audio Center from working correctly. If you can’t find the problem you can use C-Media Panel or XonarSwitch to change the cards settings.


16. Does the Xonar driver work in MSI (Message Signaled Interrupts) interrupt mode?

No.


17. Can I automate the UNi Xonar driver setup (running silently without user intervention)?

Yes. You need to do the following:

  1. You need to keep the “installsettings.ini” file that’s generated after the finish of a valid UNi Xonar driver installation with your desired installation options.
  2. The file needs to be in the same folder as the driver installer that we want to install silently.
  3. You need to add the “/silent” flag to the UNi Xonar driver setup command like this: “UNi Xonar 1823 v1.80a r3.exe” /silent

18. Occasionally I get loud white/static noise. Why is that and is there something that can be done to prevent this?

There are at least two instances:

  1. It may be a issue or incompatibility between the motherboard and the Xonar audio card. Ironically, ASUS motherboards are most prone to this issue. Unfortunately there isn’t much it can be done. You should look into updating the motherboard BIOS to the latest version. If that does not solve the problem a possible solution would be to change the motherboard if you think the card you own is worth it.
  2. A Windows 10 only issue. Discussions for this case are talking place on this page. No solution has been found so far except reverting back to Windows 7 or Windows 8.1.

General recommendations: If you run into this issues and have not found a solution you should either buy a different audio card that’s not powered by C-Media audio chips (so no ASUS or HTOmega), buy an external DAC or at least take some precautionary measures like controlling the volume with a amplifier while having Windows volume always set to 100%. Keep in mind that nothing is worth permanently damaging your ears.


19. Occasionally I get left or right speaker imbalance or volume drop. Why is that and is there something that can be done to prevent this?

There are two possible causes:

1. There is an issue with your sound system. To check if this is the case, when the volume drop occurs connect a different pair of headphones or different speaker system directly to the soundcard and see if you still have the issue.

2. An issue or incompatibility between the motherboard and the Xonar audio card. You should look into updating the motherboard BIOS to the latest version. If that does not solve the problem you either change the motherboard or buy a non Xonar audio card.


20. Sound output channels are switched between one another or I get noises/cracking/latency during 192kHz 4/5.1/7.1 channels playback.

Answer valid only for Xonar DX, D2X, HDAV 1.3 or HDAV 1.3 Deluxe audio cards:

If you card was manufactured before year 2009 you need to update its PLX(PCI-to-PCI-e bridge) firmware as the original firmware had some issues especially with some motherboards. To do so do the following: Go to ASUS download page, select Windows XP, go to Utilities, download “PLX firmware update Ver 1.1” and run it. The update utility will work on Windows 7 and probably Windows 8/8.1/10 OS versions as well.


21. I have hissing/buzzing/crackling noise coming from the speakers or headphones and/or people I talk to using the microphone complain that they hear buzzing noise coming from my end.

You could try solving this by:

  1. If you are using the case front panel connection then try connecting the speaker system, headphones or microphone directly to the card. If the issue is resolved and still want to use the front panel connection read this.
  2. Connect your PC to a grounded electric outlet.
  3. The problem might be from to much EMI (Electromagnetic interference):
    1. Move the sound card farther away from the GPU.
    2. Make a EMI shield for your Xonar card ( #1, #2).

22. I have two Xonar soundcards, how do I change change settings for each Xonar soundcard?

It’s a little tricky as there is no perfect solution.  If you have two different Xonar cards there are two options:

  • Use the Asus Xonar Audio Center or C-Media Panel to change the settings of one card and use XonarSwitch with this guide to change the settings of the other one.
  • Following this guide to control a specific Xonar card, you could make two separate XonarSwitch shortcuts, one for each card. Depending on which card XonarSwitch controls at a time, you could close XonarSwitch and start XonarSwitch again for the other card.

23. How to get a subwoofer working when it’s connected directly to the card as part of a 2.1 speaker configuration?

Connecting a subwoofer directly to the soundcard is not a standard 2.1 speaker configuration. In a standard 2.1 speaker configuration you connect the subwoofer to the speakers or amplifier.

I’ve come up with a workaround that could make it work. Guide for Windows 7/8/10:

  1. Connect subwoofer to Center/Subwoofer output jack.
  2. You need to have “Stereo upmix” enabled. Depending on your setup you either have to install drivers installed with “Re-enable stereo upmix to 4, 5.1 & 7.1” option checked or enable it in XonarSwitch.
  3. In the audio panel set the following: 2 channels and 5.1(or 6) speakers.
  4. If subwoofer isn’t sounding right, exchange center/bass channels in the audio panel.
  5. For speakers and subwoofer bass management look at the FlexBass option in the audio panel.

24. Does the StarTech PCI-e to PCI adapter work with Xonar PCI cards (DG, DS, D1, D2, ST)?

Most likely it won’t. It’s been reported that the cards work only for a couple of seconds after booting.  If you are interested in reading more about StarTech PCI-e to PCI issues with Xonar cards then check here and here.

      Which drivers have you tried? Does your STX II card work with original Asus drivers?
      If it does not and it’s missing from device manager even as unknown multimedia device then your card probably is defective.

    Hello, I’ve had issues with my Xonar Essence STX for as long as I can remember since the early windows 10 previews. HTML5 videos have their sound stutter when played using Google Chrome. It doesn’t happen with Edge/Internet explorer.

    What could be the cause? If it’s driver related, can it be fixed? Also, is it a known issue? Thanks in advance for the help.

    Hi guys

    i have a Xonar D2 and an 5.1 system Philips Hts 5540 and i connect the two through a coaxial cable
    My question is in coaxial do i use the hts 5540 dacs or the Xonar dacs?
    IF it is the Hts 5540 dacs is there a way i can use the Xonar dacs through coaxial?

    P.s: The 5.1 system has only coaxial in and stereo in so i cant use three 3.5mm jacs to connect the soundcard

    Thanks for the help!

      With Coaxial or S/PDIF you use the Philips HTS 5540 DAC. It isn’t possible to use Xonar DAC with digital connections (coaxial and S/PDIF).

    Hello,

    Thank you for these great drivers! I have an issue though. For some reason the output isn’t recordable. I can hear audio fine but any recording program doesn’t record it.

    What might explain the issue is this: When I go to Playback devices > Playback I cannot see any green bars being filled when I listen to music despite hearing the audio. When I do “Test” it does show audio being played though.

    Do you know what can be wrong?

      You need to set 2 channels on Input and 6 channels on output of your audio panel (asus xonar or cmedia panel).
      Close the app before you change the setup, and after open it again.

    Thx for all your hard work!

    I just got upmix running again (after uninstalling v1.72 and installing 1.75a, even standalone wasn’t helping anymore) and everything is fine with that. BUT is there a way to stay on 6 channel output (to have surround in games & dvds) and at the same time have upmix enabled for stereo sources? Or do I have to manually change between these?

    Cheers & thx again

      I would also like to know if there is a solution to this problem, I know this sounds like a minor issue but it’s really not as it requires changing multiple settings depending on the program used for playback and on the desired output (headphones vs speakers)

      Fortunately my headphones are connected to a separate headphone DAC so any fiddling I do to the Xonar drivers will not affect headphone playback, but it does mean however that options are limited when it comes to enforcing upmixing in Foobar or MPC-HC as an error will appear when trying to render more then 2 channels on that particular stereo device.

      One solution for Foobar playback that does not require enforce upmixing via DSPs is by using the WASAPI output coupled with the “Re-enable stereo upmix to 5.1” option in the UNi Xonar driver installer. This will upmix any stereo files to 5.1 during playback on my speakers, will correctly render 5.1 files (L to L, LS to LS, etc..) and has the added benefit that it does not break headphone compatibility and will correctly output stereo files on headphones by simply changing the renderer.

      Of course, the above works only for Foobar, as playback from MPC-HC, Games, Firefox, etc.. will still not fill the unused channels if the drivers is set to the 6CH mode, and of course if I set it to 2CH, games, movies and surround albums stop working. I could enforce upmixing in MPC-HC, but that’s more of a hastle, and of course, it will break compatibility with headphones output, especially on movies with only 5.1 audio tracks as the mixdown will no longer be performed.

      It’s… really a hastle, and the fact that the drivers ARE capable of stereo to 5.1 upmixing even on 6CH via WASAPI makes me hopeful that a solution might be available for DirectSound.
      And before you ask, yes, I double checked in Foobar: DirectSound Speakers output is limited to Front L and R on stereo files, wheres WASAPI will clone the sound to the Rear/FC speakers, all other settings being identical.

    Any idea what’s going on here. I’ve had this problem since I’ve had the card. Sometimes after a fresh install of windows, I’ll install the sound drivers and the sound will be absolutely fine. But other times, like recently I’ve just gone from Windows 7 to Windows 10, the sound volume is reduced a lot, and music sounds quite shallow and a lot less ‘punchy’ – is the best way I can put it. When the sound is OK, I can play music at 3%-5% and it’s really loud and sounds really good, but when it decides not to behave, I have to set it at 20%-25% to get anyway close the same volume, but yet it doesn’t sound the same.

    In both cases I’ve had the settings the same, headphone gain on +12db. I’ve tried both official Asus drivers and Unixonar drivers, reinstalled multiple times, reseated card and swapped out 12v molex for a different one.

    It seems like it’s a power thing, like the amp isn’t getting enough power to drive the headphones. But I don’t undertand, because it can’t be a hardware problem when all I’ve done is reinstall Windows and not touched the card.

    Hello! I had a problem with the volume of the front right channel. Sometimes it reduce to very low lvl ONLY at right front channel and i need to restart my PC to get it back.

      I’m having the same issue, restarting the card from control panel fixes it. It gets quieter and quieter until only left channel works. Win 7 64bit
      If you can’t restart the card from device manager, go to sound playback devices, and disable speakers first. This operation will crash xonar audio center.

    I’m running the Xonar Essence STX on Win 10 64 bit.. I’d like to try the Uni Xonar drivers. What is the best way to uninstall the existing drivers and remove all the crap?
    Thank you

      Uninstall current drivers. Restart. Install UNi Xonar drivers with “Run driver cleaning before install” option checked.

        Thank you CarvedInside. It went smoothly and all sounds good!
        I’m using SPDIF out to a M51 DAC and Adam A8X powered speakers. The headphone option is from the M51 DAC to a Violectric HPA V90 Amp and Sennheiser HD800 phones.

          Glad it worked out smoothly and thank you for the donation.

          Regarding your setup I may have some advices. I’m not sure if you know but using the Xonar with SPDIF output is no different than using the onboard audio card SPDIF output or by connecting the M51 DAC directly to the USB port on the PC. Xonar STX DAC and op-amps are completely bypassed and there is only the digital signal (1’s and 0’s) that gets out to the M51 DAC. M51 DAC does all the sound processing. To actually use the Xonar STX card you would need to use the soundcard’s analog connections (like connecting the Violectric HP Amp to the card).
          Now the DAC and op-amps included in M51 DAC are probably better than those in Xonar STX. If you are unsure you could find out by testing each with Right Mark Audio Analyzer. You would have to check the Xonar STX analog output connected to the microphone input. For testing the M51 DAC you could either use the current SPDIF connection or the USB connection and connect a cable from M51 DAC output to Xonar STX microphone input. If you do these tests I’m interested in seeing the results.
