RELEASE NOTES

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.
  • Windows 10: Fix for microphone not working with some 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).
  • Includes updated driver installer, ASUS Audio Center and C-Media Panel.

Other notes:

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

Possible issues:

  • Microphone stops working if running specific programs. If you run into this issue please report it in a reply to the original report. If you run into the issue you can switch to v1.75a drivers or connect the microphone to the onboard audio card microphone input.
  • WASAPI playback issues might occur with some soundcards
  • Occasionally when waking PC up from sleep the Xonar card does not output any sound.
  • 1.80b “STXII”

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

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.

  • 1.75b “STXII”

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

Rev.2 changes:

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

Driver changes:

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

Known issues:

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

Notes about Windows 10 RTM compatibility (updated 28 Nov 2015)

UNi Xonar drivers above v1.64 will work in Windows 10 but since the audio drivers are not yet made specifically for Windows 10 there could be some issues that you could run into depending on audio settings used. Different drivers could work differently so if you encounter any issues try installing the other UNi Xonar versions.

Apart from driver issues there could be issues solely from Windows 10 sound system that would be fixed with future Windows updates. There is also a small chance that some things could break with future Windows updates.

Update 28 Nov 2015: The Windows 10 Threshold 2 update does not seem to fix many of the sound issues that where present so far and it may introduce new ones. In my opinion Windows 10 is a very buggy OS, the only things working fine are the spying of its users(#1, #2) and the periodic removal of user preferences and programs(#1, #2, #3, #4).

Update 19 Oct 2015: The audio fixes from Insider Previews >= 10547 will probably be included in the upcoming “Threshold 2” update that will be released around November 2015.

Update 1 Oct 2015: The Windows 10 development team is fixing some audio issues with Windows 10. The fixes where made available for testing starting with Windows 10 Insider Preview build 10547.

100% compatible drivers when?

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

Update 01 Oct 2015: 1823 audio drivers are the first drivers released for Windows 10 by ASUS/C-Media. Whether they perform any better than 1822 or STXII 11.5 drivers remains to be seen.

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

Update 27 Aug 2015: The stutter issues on youtube are  fixed with the latest Chrome build released on 20 Aug 2015 (v 44.0.2403.157). Reports indicate that stutter issues are still happening for videos on other websites (eg. daily motion, facebook, instagram).

Update 7 Aug 2015: After some testing and some reading it seems that the stuttering issues are not related to the UNi Xonar drivers. I’ve got the same behavior with Realtek’s onboard audio and from what it looked liked. My guess the issue is caused either by Windows 10 or Chrome.

There is a Chromium issue opened here.

Here are some things you could try:

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

    Hi!

    In September it temporarily had win10 with a Xonar D1 and uni-xonar and got constant crackling, popping.
    Did the driver update that came after that (1.80) fix it it for anyone who had similar issues?

    I finally managed to find what was causing the BSOD on my Xonar DG and windows 7, it was “headphones mode” >64 since I have a 250 headphones I pretty much need it
    After weeks of it in “2 speakers mode” I had no BSOD
    Is that a know issue with some workaround/channels/sampling config or just the hardware is broken?

    i installed the 1.80r3 driver (low latency version) on my system which has a auzentech x-meridian 2g.
    now i see two playback devices in win7, the typical ‘auzen xmeridian’ one which has all the normal properties im familiar with,
    but i also see a new ‘cmedia oxygen hd converter’ listed as a speaker under playback devices….
    what is this second device, and when/why should i ever use it, since it was installed by 1.80r3?
    thanks

    Hi, I really love the work here. But I’ve been getting this high pitch whine issue with my Xonar Essence STX on Windows 10. Is this a know issue and is there any kind of fix/method of preventing it? I have had it 2-3 times in the past few months. Exactly the same as this guy here: https://www.youtube.com/watch?v=KVo9pwQ-W5I

    I noticed Linux (PCLinuxOS) giving out better sounding audio; richer sound with Xonar DX1. Why is that? Has or can the dev of UNi’s drivers check how Linux makes it work?

    Reply

    • CarvedInside    07 Apr 2016 @ 19:41   

      I don’t know. There is a possibility that what you are hearing is a placebo effect or they just sound different by having slightly different default equalizer settings. I don’t know of any objective way to check this claim.
      There is nothing I can do to the Windows Xonar drivers from looking at the those Xonar Linux drivers.

    Quick query- never used to be an issue so a bit perplexed. Am running 1.75a on Windows 10 Pro x64 with a Xonar D2X. Windows is telling me that the device / driver is preventing entering sleep due to a System Required Request. Is this a known issue? Anyone know of a fix?

    Reply

    • CarvedInside    21 Apr 2016 @ 14:23   

      But is something actually preventing your system to go to sleep or this is just shown in a report? There shouldn’t be any problems with sleep, at least with previous OS’s. If you have issues, try installing the drivers again. Are you by any chance using the ASIO output playback?

    Hello! Having this strange issue with my Xonar DG (UNi Xonar 1.80a r3, W10, Harman Kardon Soundsticks older model). After a system restart (maybe even waking from sleep, not sure, doesn’t happen always), I get no sound from the speakers. Windows volume settings are ok. It will only come back (immediately), if I just touch the volume control on the speaker i.e. the sound comes back the moment I alter the volume from the speakers. This didn’t happen with the onboard audio – not sure what can cause this.

      Hi. If I understand correctly you are touching the volume control on the speakers and not the Windows Volume Mixer for the speakers. If that’s the case I don’t see how this could have anything to do with the Xonar card.
      What I’ve noticed while using UNi Xonar 1.80a drivers is that many times after waking the computer my speakers weren’t getting any sound. Now since I went back to 1.75a drivers I haven’t had this issue.

      Reply

      • George    24 Apr 2016 @ 20:51   

        Thanks CarvedInside, yes that’s correct. My assumption is that perhaps the drivers/card might send a ‘wrong’ signal on a system restart (or no signal at all) and the speakers automatically enter their mute (or self-protect?) mode? Probably not though. I’ll try the recommended 1.75a drivers to see if this still happens.

    HI
    I am facing 2 issues with my DX:
    1.crackling sound with 5.1 analog at 192khz
    2.slowmotion sound with 7.1 at 192 khz

    I have changed my motherboard previously it was working flawlessly. Previously I had different motherboard and processor which was Gigabyte and FX4300 and now have Asus le r2.0 and FX6300.
    After the new motherboard I am facing this issue what should I do?

      I’ve corrected your post so it can be easily read. If you want for people to help you please make an effort to write and format your text correctly next time. Add “.” at the end of the sentences. Write the names with capital letter (Gigabyte instead of gigabyte).

      How old is your Xonar card? If it’s manufactured at least 4-5 years ago, you could try updating the cards PLX firmware.
      This firmware fixes more things than those in the log. For downloads and instructions go to Asus Xonar DX download page, select Windows XP, go to Utilities and download PLX firmware update Ver 1.1. It works on Win7 (and probably 8/8.1/10) even if you’ve selected WinXP.

      You should also look into updating your motherboards BIOS.

      Update: Updated the link.

        Would it be useful updating the firware on a D1? (Although I don’t see firmware listed for it.)
        I’ve always had problems: The left side going silent. Getting white noise after a seek.

        PS:
        That link is broken. It redirects to the support main page.

        • CarvedInside    26 Apr 2016 @ 19:43   

          The firmware update is not for Xonar D1. The firmware update is for PCI to PCI-E bridge that PCI-E Xonar cards have.
          Your problems are from something else, maybe a bad card or a motherboard incompatibility.
          Thanks for the heads up regarding the broken link.

    Hi, I use a Xonar DX on Windows 10. There it is necessary to select the number of source channels. (2 for MP3, 6 for movies etc.) Is it somehow possible to let the soundcard detect this option in an “auto-mode”?

    On an old computer with Windows XP running, the Audio Channels Selection isn’t even existing.

    • George    28 Apr 2016 @ 01:15   

      Check the FAQ, point 9 – your answer is there. No need for “auto-mode”.

      • Facu1ty    28 Apr 2016 @ 11:21   

        When I leave the number of source channels on 6, I cant use Dolby Pro Logic IIx to upmix stereo files back to 5.1. This just appears when I select 2 channels.

        I live in Germany. Unfortunately, Amazon prime for example offers no Dolby Digital 5.1 soundfiles on PC. But nearly every stereo soundfile countains the surround informations I want to hear. So at the moment, I have to choose 6 channels for Blu-Rays and DVDs and 2 channels for “Online-Movies”.

        Is it possible to install a Windows XP driver on 7?
