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 make 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 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:

  1. 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.
  2. Following this guide to control a specific Xonar card, you could make two separate XonarSwitch shortcut, 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.

    I did everything as described to enable the upmix. It simply does not work. It used to work perfectly with my 5.1, but then suddenly it won’t upmix anymore. I even reinstalled Windows 7 – still not working! Tried all driver versions. Still not working. Tried my Teufel system on my buddies PC, who also has the XONAR DG – not working!
    So upmix for me is definately broken.

      Don’t think stereo upmix disables itself as time goes by, I myself am using stereo upmix to “power” my headphones at the same time as the speakers and it does not turn off.

      I think its because of some option that you enable at some point, and that disables stereo upmix. Stereo-upmix switch app might help you turn on stereo-upmix in the drivers, thats if you’ve disabled the option that caused the issue in the first place.

      A similar issue is presented in the Known issues section of the driver release log.

        Tried the steroe-upmix switcher app. Didn’t change a thing.
        I definately did not mess with the settings. Reinstalled windows – problem is still there. Music just won’t play on the other speakers and subwoofer is also dead. It doesn’t matter if I set it to 2,4,6,8 channels.
        Any other suggestions =/?

          If you switch to 6 channels / 5.1 speakers, and then test the individual speakers in the Asus/Cmedia Panel and also in Windows Speaker Setup, does every speaker respond ?

    I have an Auzentech X-Meridian 7.1 2G, cannot get past driver installation as it tells me to plug in a Xonar device, although it is to my understanding that C-Media chips are supported?

    Reply

    • CarvedInside    27 Apr 2013 @ 22:40   

      Drivers work with X-Meridian 7.1 2G, the installer is customized for Xonar cards and thus the message from the error. Sometimes there are problems with the driver installer.

      Try following the installation methods from this topic. Try first with Possible solution 2.
      If you still can’t install you can try and enable Test Mode.
      Let me know if you manage to install the drivers or not.

    Hi!
    With the original ASUS drivers, i was able to play two different audio streams simultaneously, like this:
    -games, teamspeak, youtube on speakers/headphones using the analog out and selecting spekers for default playback device in win7
    -music, movies using the spdif out, selected in thier playback software (foobar2000, xmbc)
    With the UNi Xonar drivers i can’t do both. Is there any solution for this?
    (Essence ST+H6; Win7 x64)

    • CarvedInside    21 May 2013 @ 10:21   

      Try installing the original drivers and see if it still works. My guess is that it won’t work, and that the issue is actually a configuration issue. I don’t have SPDIF receiver so can’t really be sure that it works for me, but I have setup up my configuration like yours and at least in Playback devices , both Speakers and Digital Out Volume Meter bars light up.

      Make sure you have “DS : Digital Out (Asus..)” as output in foobar preferences and not WASAPI or ASIO.
      BTW your issue sound similiar to this one.

        I tryed DS gigital out with the UNi driver, still dont work.
        I reinstalled the original drivers and all things worked fine, with wasapi or asio out too. I set the following things after reinstalling the driver: Audio chanel 2, sample rate 96khz, analog out headphone, spidf out pcm; then i go to the playback devices, i set the speakers for default.

          Then if you wish you can try previous UNi Xonar drivers(1.70, 1.64, 1,62) as it might be a bug in the audio drivers used in the 1.71 release.
          Let me know if those work or not.

    hey guys, i need your advice since i am a noob at this… first time i install Uni- Xonar drivers 😀
    i have a asus D1 and i use it with roccat kave 5.1 headset… i dont know during the installation if i have to Re-enable stereo upmix or not…
    i use my pc 70% for games, so how do you suggest to set up the installation?
    thanks a lot

      If your OS is Win XP then leave it off.
      If your OS is Win Vista/7/8 and use analog (jacks) connection you can leave it checked.
      If you haven’t read it already I suggest you read the FAQ:Q&A 9

        thanks for help
        but about the stero upmix you said to enable it for Win7 (and yes my headset uses 4 analogic jacks to connect audiocard :))
        i just read this in the FAQS:
        “While 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 , do not 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.”

        Now i have set 6 channels and output 5.1 , does it mean that if i reenable upmix then i will have 2 channels and not anymore 6?
        thanks for help 🙂

          You don’t need stereo upmix to be enabled. The option in the installer lets you be able to enable stereo upmix on Win7.
          Just set 6 channels and output to 5.1 and you are fine regardless if “re-enable stereo upmix” was checked or not in the installer.

    I installed 1.71 version but cant see the 5.1 7.1 speaker configurations on the Analog Out Section, it only shows me headphone and 2.0 speakers options…. i try everything even drive sweep and reinstall the xonar stx orig drivers….dont know what else can i do… help please

      It has nothing to do with the drivers. Since the ST/STX cards have only 1 analog output you can’t connect 5.1 speaker configurations through analog, only if you purchase a Xonar H6 Addon, or if you use S/PDIF connection instead. Next time, please consult the spec sheet and manual of the card you bought and use google before posting in a unrelated topic.

    I need help installing the latest Drivers (I have a Xonar DX)

    1-I clean my previous drivers using the guide posted here.
    2- Proceed to install the drivers, when the setup tells me that is is “Installing the drivers. the process should not take longer than 60 seconds” it opens another little window where it is saying ” Installing UNI Xonar Audio Driver…” the fills up very slowly and takes more than 60 seconds, more like 10 minutes. After the bar fills up completely, it just stays there and nothing happens.

    What am i doing wrong?
    After some more time it tells me: “Please Plug In UNI Xonar Audio Device” but it is weird because i had the official drivers before.

    Hi (warning this is a massive amount of text for a problem I think I have already narrowed down at least somewhat)

    I recently bought the Startech PCI-to-PCI Express adapter and I have run into a few issues.
    I bought it to allow my Asus Xonar Essence ST to work on my all PCIe system:

    Here is a link to the Asus Xonar Essence STX which is the PCIe version and it shows that the STX has a bridge chip built in:
    http://www.guru3d.com/articles_pages/asus_xonar_essence_stx_soundcard_review,7.html

    The difference is mainly the interface and the ST does not have the PCI-E to PCI Bridge Chip PEX 8112 that the STX does.

    Now I have installed the startech adapter and the sound card, and it was detected correctly, I installed Uni Drivers and the device installs the drivers correctly, and will test correctly (to a point) but the moment I start playback the device stops responding completely, it refuses to test aswell thereafter. Sometimes it even stops during testing.

    To cover all the bases I did extensive testing. This is what I all tested:
    – Different versions of drivers, both official and Uni Drivers
    – I even attempted the STX version of the Uni drivers, and it successfuly installs and works but same issue.
    – The player (MusicBee) is not the problem – multiple players were used, and multiple output methods were used (DirectShow, WASAPI and ASIO)
    – So I can confirm its not a setup issue (not in comparison to a normal setup.)
    – I put the soundcard into another pc (without the adapter) using the Uni drivers and it works perfectly with any player and any output method.
    – I then tested the soundcard in that other pc with the startech adapter and the same issue occurs, it tests fine to a point and disappears after attempting playback.
    – I am also successfully using an Creative Recon3d (which is shit) so its not an issue with the PC (I disabled this for tests just incase.)

    I just want to clarify its easy to test if the soundcard is responding because it has very loud relays, and if I change an input or output setting you can hear it click, and it stops doing this after playback fails, the device itself is still visible to the PC and still shows as functioning in device manager, but any attempt to test or play anything stalls and fails.

    I suspect the issue is somewhere in the default PCI-to-PCI drivers in windows or the Asus drivers, Unfortunately I couldn’t test in linux. But after doing a lot of looking it looks like it exists there with different devices too.

    Here is a different error that I think may help us in narrowing down the issue with the startech adapter:
    http://vip.asus.com/forum/view.aspx?board_id=21&model=Xonar+Essence+STX&id=20110312101917644&page=1&SLanguage=en-us

    So I definitely think the drivers are blocking the device or something to that effect.

    Here is a working example or what I am trying to achieve (with a better quality product then the one used in this example):
    http://www.overclock.net/t/1254890/running-the-xonar-essence-st-on-pci-e-board

    So to finish off and narrow things down I believe it may be Related to the IRQ an I/O address. Since Win7 x64 is assigning the Startech adapter and the ST the same range (which from my reading is perfectly fine unless the drivers have issues)

    ASUS (PCI bus 4 device 4 function 0): C-Media CMI8788 Audio Chip
    IRQ: 0x28 (40)
    I/O Range: D000 – D0FF
    StarTech (PCI bus 3 device 0 function 0): Pericom PI7C9X111 PCI Express to PCI Bridge
    IRQ: 0x28 (40)
    I/O Range: D000 – D0FF

    Possibly IRQ Errors?

      Sorry I can’t be of help to you in this issue. One thing you may want to consider is that maybe the adapter is faulty.

        I’m definitely working on it, Just got a response from StarTech. Since this may become a more common setup with PCI being phased out, II will keep you updated.

          Please let me know if you figure anything out with the StarTech adapter. I am using the adapter as well and having the exact same problem as you. IRQ assigned to both parts and playback stops at random. I can get it to play for 45 seconds sometimes and then other times it will stop within 10 seconds. There is an “Audio re-starter .bat file ” linked on this site under other apps: here is a direct link – http://www.mediafire.com/?js0bnx4u93m5rrj – but if you run it after the sounds cuts out you can get sound again for another 30 seconds or so. You can repeat this about 3 or 4 times until it finally stops working and you need a restart to get playback again.

          I am located in San Diego and I have actually driven past the StarTech store, I believe its in El Cajon, CA. What advice have they given you? I wonder if I brought them the ST card and the bridge if they could do anything to troubleshoot or update/change the bridge driver. Just a thought.

            Hi, no no solution yet. I have spoken with star tech, but i haven’t yet tested the adapter with another PCI card (because i didn’t have one) I now have an old NIC card I’m going to test, but time has been issue. This is to eliminate the adapter being faulty, and this is where I left off with StarTech support.

            Kii I think if you could take the ST and the adapter to StarTech directly then maybe they can figure it out. They were extremely helpful in the emails I had with them. (i’m located in South Africa, which makes things difficult.)

            I gave them a lot of information, but I couldn’t determine what the PCI error (1 non-fatal it think) it was that PCIScope kept picking up was.

      Hey WiR3D have you got any where with this? I have the same exact problem and also have the startech bridge. Did you find any type of work around or solution or did you give up on it and get something else?

    Hi, I am trying to install the latest UNi drivers for a brand new Xonar DGX. The install takes a long time then says “Please plug in UNi Xonar Audio Device. I checked this page and noticed someone else had the same problem. I checked the EEPROM, but it is working as intended. I also turned on test mode and clicked the check box to bypass digital signatures in the installer. I am still having the same problem, and the other person here didn’t come back and say if they got theirs fixed.

    Some specs if it would help you:
    i3 3220
    4gb RAM
    Windows 7 x64 Ultimate

    Also, I forgot to say that between each installation try I fully cleaned the drivers as to not have any conflicts that way.

      Try the possible solutions 1 & 2 from this page.
      Do original drivers work? If they do not work, and neither uni xonar after trying the solutions from the link above then it might be a hardware defect.
      Let us know of any developments.

        Thanks for the reply, I will attempt these when I get off work and report back to you. Regardless of if this works for me or not I wanted to say thanks for taking the reins where Asus failed to, it’s much appreciated.

        Alright I got them installed and working. What I had to do was run the driversweep batch file and then driver sweeper and install the UNi drivers in safe mode. The first method on that page didn’t work, but thankfully the second did.

        So for anyone having similar problems try making sure you clean all the driver files and then install it in safe mode.

    “Setting the Windows audio playback to 24 bit might improve audio quality.”
    Why 24 bit instead of 16?

    Hello
    I need some help with GX..Winamp through “Nullsoft Direct Sound Output” reports that my Xonar Essence ST have no hardware mixing or hardware memory..I remember if i enable GX those fields change and the card is correctly detecting that the card supports hardware mixing and number the channels from 32 to 128..Do i need GX enable to get full and correct sounds for games for example..I don’t need EAX emulation because i know it’s crap but i need those 128 channels so i get full sounds reproduction in some circumstances like many sounds at the same time…Pls advice..Thx in advance

    My rig:
    I5 750
    8 gb ram
    Asus Essence ST with unixonar 1.71 Cmedia panel only for reduced DPC latency

    win 7 64 installed latest UNI Xonar drivers but it kind of messed up the sound. I want to revert back to ASUS drivers Now but I cannot uninstall the UNI drivers.
    Help all this quiet is sending me deaf

      I am not sure why you can’t install the Uni Xonar drivers, what’s happening when you try to uninstall them in Programs and Features?
      UNi Xonar drivers giving messed up sound isn’t normal behavior.
      Try using system restore to revert your system prior to installing UNi Xonar drivers if you are having problems uninstalling the drivers.

    Hi. I don’t have your drivers installed in my system but I’m looking into it. I just don’t know if they are the solution to my problem:

    Recently, using other hardware and software (Galaxy S phone with Voodoo Sound hack), a developer wrote that the best solution is to set digitial amplification (software) to its maximum and use analog gain in DAC to achieve desired volume while listening to the content, in order to get the best SNR and other advantages. On the fly I thought about how to do that with the Xonar, given that analog gain isn’t adjustable as a regular volume level and I’m actually using software (Foobar) digital amplification when listening to music.

    I went through several boards and somebody said that with ASIO v1 you can adjust analogue gain, but you can’t with ASIO v2 wich provides always 100% gain, wich is what I have in my system with the ASUS drivers. I’m guessing, therefore, that Foobar is messing with the audio thread when I adjust volume, and ideal things would be to have Foobar at 100% volume and adjust only analog gain in the ASIO control.

    Question is, does you driver provide analog gain control as it was volume level? I read that your driver comes with ASIO v2.

    Excuse me if I’m not explaining myself correctly, its a confusing matter for me.

      This driver will work just as the Asus drivers in this regard.

      I think you misunderstood the tip. I think whoever wrote the part with the analog gain in DAC was referring to the fact that you should control the volume by DAC’s(standalone) volume knob.
      You don’t have this on the internal audio cards (which yes they do have a DAC), for them you control the volume in Windows volume and in the audio application and thats it, there are no other volume options or a special analog gain.
      The suggestion that developer wrote would be like this: set the cards volume sliders to 100% in the software and Windows, and control the volume only by volume knobs in the audio equipment you are using (DAC, amp, receiver..)

        Hi, CarvedInside, thanks for your reply 🙂

        I lack technical knowledge so I don’t know the hows, sorry… but this app controls analogue gain via phone’s DAC (a Wolfson WM8994 chip) while everything software-related (player, mixer volume) stays at 100%, from -57db to +5db, Maybe this chip it’s not only DAC but also headphone amplifier?

        Anyway, I’m wondering how the Xonar hadles the gain: It has 3 or 4 settings for the headphones. Wouldn’t be possible to adjust the gain from x to y pogressively like the phone?
