Read Previous Release Notes

 

Note about Windows 10 Tehnical Preview builds compatibility (updated 28 Mar 2015)

UNi Xonar drivers above v1.64 will work in Windows 10 TP but since the drivers are not made for Windows 10 TP there could be some issues here and there (e.g.,  this one). Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions.

Due to changes within the Win10 TP builds, the very slow development of the audio drivers by C-Media and the long time it takes for C-Media partners (ASUS, HTOmega)  to release the new drivers, it may take a while before we have a 100% compatible driver for Windows 10.  It could take up to 2-3 months after the final release of Windows 10.

    I’m unable to install the latest Unified drivers, keep getting the following error “Please Plug-In Uni Xonar Audio Device!” I have a Xonar HDAV 1.3 SLIM

    The official drivers seem to install fine. Any ideas? I’m using windows 8.1

      I see you finally managed to make a new comment instead of replying to someone else’s that has nothing to do with your problem. Now how about reading the post above, there is a link “Having problems installing UNi Xonar drivers? Refer to this topic” or you could have searched for “Uni Xonar Please Plug-in…” or other things. I’m not trying to be smart ass but if you would know how many times I’ve been asked this question and I’m kinda sick of people not giving a damn about my spare time. So please next time try to make an effort and pay more attention to things already written and try searching for an answer before asking. Also, when asking for help you should not hold out any essential details, in your case you have Win8.1 x86 or x64 and which is the exact version of the drivers you are trying to install.

      Hi, great work to both the UNi Xonar drivers and Switch creators! A question, why don’t add support to OpenAL Soft when installing the drivers instead of the deprecated and proprietary’s? Thanks! : D M. C.

        Hi.

        First I want to make a remark. You’ve replied to someone else’s comment that has nothing to do with the content of your comment. Instead, you should have made a new comment using the form at the bottom of the page.

        Now getting to the matter at hand. Thanks for bringing this up. I was considering replacing the OpenAl with the OpenAL Soft in future versions. Have you tried it with the Xonar drivers? I have to know that it would work fine.

    Hi,

    Is it possible to have 7.1 Virtual Speaker without enabling Dolby Virtual Speaker? I have Xonar U3, but I had a DGX which had C-media panel which could do that, but not with Xonar panel.
    I’d like to have that 7.1 feature without adding any additional reverb.
    PS: I know Uni Drivers don’t work with U3, but figured you guys must know some method to do that within Xonar panel or with some hack-ish method.

    Thanks in advance!

      Hi. I found the registry value for enabling only 7.1 Virtual Speaker. It may not work for U3. It may also be overwritten once the ASUS Panel loads so you may need to prevent it from starting. The ASUS Audio Panel for the internal Xonar’s does that.

      How to enable it: 1) Find the Xonar U3 registry settings, see FAQ Q&A 5. I suspect you are using the U3 in another system that the one with the DGX, if not you will have 2 registry keys (folders).
      2) Add/Change the “EnableXear3D” value data from “00 00 00 00″ to “01 00 00 00″.
      3) You can export the settings so you can load them again if necessary.
      4) Disable and re-enable the U3 from Device Manager or restart the PC.

      Hope this helps.

        Thanks, that worked! Though, I was dissapointed to see that it’s not really the same as DGX. Moving R to L position and I still hear sounds in R speaker when only L speaker should have sounds from L and R channels (I did disable everything before the regeddit trick).

        Anyway, thanks for showing me that trick, certainly something to play with.

      Hi,
      Please use the reply button properly. When replying to an existing discussion use reply button floating on the right of the comment you are replying to.
      If you are using a NoScript browser addon then you should disable it so that “reply to discussion” button works correctly.

      In your case you should reply to this comment. If you’ve pinpointed what caused the crashes, you should let us know what it was.

      Hi. Because it’s a minor inconvenience, there are a few who have non-Xonar cards that use UNi Xonar drivers and making the change would take significant time.

          I will try to continue to support the X-Meridian & HT-Omega cards in future UNi Xonar drivers. Lets hope that C-Media does not remove those cards from the audio drivers.

    I want to start by thanking you all who helped develop and continue to develop and maintain these drivers, as well as those of you who have made donations, have helped spread the word about these drivers, or otherwise contributed to the cause of this project.

    The first time I discovered these drivers is when I started researching latency issues with ASIO and Propellerhead Reason, and when I realized that ASUS was not going to do anything about it. They would not have updated the drivers to work well with Windows 8 either if they had not been pressured by users (not saying that those drivers do work well at all, in any Windows version they supposedly support). Later, I learned that Windows 10 technical preview had no support for my ASUS card either. At that point, I had to switch. Up until then, I have always been using the official drivers. Seeing now what options I have with UNi Xonar, I probably will never switch back to the official drivers. I never had the chance to test out these drivers with Reason; I stopped using the software instead, until I buy a new audio card I thought… but I never did.

    What makes matters worse for me is that the Realtek audio device on my motherboard is not working at all. I think I fried some audio ports once when I made a wrong connection, although the digital in and out appear operational but I’m not sure if they ever worked again after that. I’ve been using the Xonar Essence STX since then. I’m on Windows 10, build 10049 now and there is still no built-in support for this audio device. Unlike with Ubuntu 14.10 or Fedora 21 where it works OOB. The Windows 10 preview appears to have overall issues with audio devices across the board, with many audio devices.

    Some individuals do for free what big name companies can’t (won’t) do for pay. Perhaps there is still hope for humanity after all.

    Hello,
    I’m having trouble with the stereo mix volume on my ASUS Xonar Essense STX. I noticed while using these drivers that the volume of the stereo mix audio recording stream seems to be dependent upon the windows volume mixer level for the speakers themselves. I don’t know if this is how this is supposed to work, an oversight in the development of the driver itself, or if this is related to a bug in the windows vista+ audio mixing system which, quite frankly, sucks.

    To more specifically describe my issue, I’m trying to record stereo mix while listening to my computer with headphones. Not wanting to lose my ears I have the windows audio speaker volume at about 25. This seems to produce almost no sound on the stereo mix channel. Adjusting the volume of the stereo mix channel (which is already at 100%) only further reduces it’s threshold. Another peculiar bug I seem to notice is that even when I turn the windows speaker volume down to 0 the levels on the speaker VU meter in the windows playback for the ASUS Xonar Essence STX look completely unfazed, something I would expect/want from the stereo mix stream.

    Why is the stereo mix volume dependent upon the actual speaker volume? This seems counter intuitive and just “wrong”. Is there a way to shut this off?
    Sincerely,

    BustyLoli-Chan

      Hi.
      It unclear to me if you did you noticed this with original drivers? The UNi Xonar drivers you’ve checked? Your OS is?
      I am unfamiliar with the issue you are describing. To know if it’s a issue related to the Xonar drivers or the windows audio mixing system you could check if you get the same behavior with the onboard audio.

    Hi,
    I just wanted to thank you for these drivers.
    I used them for a long time, and then during my attempt to try out Pro Tools and get it to produce sound, I tried reverting to stock drivers as part of the troubleshooting.
    Immediately upon playing this song https://fractaleyes.bandcamp.com/track/mushroom-ancestry I noticed a distinct… lack… in the bass. I don’t have the vocabulary, except to say it was weaker and more hollow perhaps. I’ve just gone back to the uni drivers and the delicious warm sound has returned, so thank you again!
