Driver installation failure – possible solutions & discussions page

<-Back to the main page

This page is mainly related to installation problems on Vista, Win7, Win8, Win10 – x64 versions.

Problem description: driver installer hangs and does not finish for minutes or it shows the following message :”Please Plug-in UNi Xonar Audio device!”.

Attention: Before trying any of the possible solutions be advised that on Vista, Win7 & Win8 x64 versions the following cards will (in most cases) need test mode enabled in order for the drivers to install:

  • 1.75b, 1.80b – all cards except Xonar STX II
  • 1.70, 1.71, 1.72, 1.75a, 1.80a, 1.81a+  – HDAV(+Slim), Razer Barracuda, Xonar STX II

  • 1.51-1.53 – HDAV(+Slim), X-Meridian (1,2), HT Omega cards, Razer Barracuda AC-1

Before trying any solutions please uninstall current audio driver and restart.

I recommend you try all the possible solutions presented and not only the last one.

    Hi there!
    I’ve discovered a problem with 1.80a driver on my Asus Xonar DX. In some cases I can hear a cracking sounds when some low sound is played. It is not heard all the time and looks like it’s bound to one specific frequency (waterfall-like sound). It’s not loud, more like a echo. For instance, it’s almost never heard in DOTA2 but heard frequently in Prison Architect. Adjusting sample rate from 44,1 to 48 both in game options of Prison Architect and driver have changed nothing, so does audio channels option. I’ve just switched back to 1.75a r2 and problem have gone.

    My instalation failes no matter what. I’m running in testing version with disabeled signature verification, even tried it in safe mode. Failes every time. There must be something I’m missing. Windows 7 64-bit, Asus Essence STX II.

    I have tried to install the drivers a few different ways, even tried the stock Asus drivers but my problem still prevails.
    My problem is that every time I try to open the Xonar audio center, it says “Can’t find any device” I’ve done several clean installs, using the number one method etc and still no luck.
    I have an Asus Xonar Essence STX sound card running on windows 10 64 bit. The Uni drivers used to work great, but during some point, I started to get this error code, any fixes for this problem?

      But does the sound playback works? If yes then repost the comment under the main UNi Xonar page since this page is for driver installation problems and not for “Asus Audio Center” or other auxiliary driver components problems.

    AsusAudioCenter does not show up after installing. UNi Xonar 1822 v1.75a r2 for Asus Xonar Essen ST on Windows 7 x64.

      Did you run the installer or just installed driver only files from “Possible Solution 1” above? If you run the installer, did you choose “Low DPC Latency” or “C-Media Panel” configuration? Look for “Xonar Audio Center” under “Start->All Programs->UNi Xonar”. If it’s not there look for AsusAudioCenter.exe in “C:\Program Files\UNi Xonar Audio\Customapp”. If it’s not there either then it’s possible the installation failed. You should try installing 1.80a r2 drivers and see if that gives you access to the Asus Audio Center.

    Hi guys!
    My version of the solution to the problem of Xonar EEPROM failure and the message “Please Plug-in UNi Xonar Audio device!” (for Xonar D1 & Win7 x64)

    I did not help the utility of the “alsa-project” restores the original ID, she could not see my soundcard from under DOS. But the problem was solved by installing a sound card to another PCI slot! After the restart of the system IDs match the original, and I was able to install the UNi Xonar drivers (UNi Xonar 1816/1823 v1.80a r3).
