      Hi. The update is for un-updated Vista OSes. You can’t install it because it is not design for Win7 SP1. The problem is somewhere else. You should check the card in another PC, if you still get the BSOD then the card is faulty.

      HI Dade – If you’re still having this problem try this to at least regain your sound:

      Make sure the sound card is fully seated (pushed in and connected)
      Completely uninstall drivers for your card and delete ONLY it’s relevant folder and re-scan hardware – DO NOT install automatically (This is important)
      Manually find your drivers from your sound card CD and install.
      Reset your PC and see if you have sound.

      This worked for me when my old ASUS XONAR DS screwed up – I hope this is of some help.

    Hello,

    I have a asus DG SI and seems that when I talking with someone he can hear a annoying buzz sound so I activated the Monitoring options and sandly he was right.
    So i tried many settings in asus control panel and i didnt get rid of that buzz sound, the only way was to deactivate microphone boost and i didnt hear no more the buzz sound but the problem is that no one can hear me when talking on mic.
    On realtek i could change manually the db of the microphone but on this asus xonar dg si i see only option to disable or enable microphone boost with no option to slide de db so do you have any suggestion for me?
    Thank you.

    I just got my HTPC fully running, loaded the 1.75 drivers and can get video / audio direct from my MDB HDMI port, but when I connect it through my Xonar Slim 1.3 input, there is nothing coming from the HDMI out. I have tried both HDMI and DVI inputs to the Xonar (via the supplied cable) and neither works. I can’t see any settings in the manual so can you help?

    Many thanks…TomP

      Just a thought, does the HDMI pass-through itself need any drivers and if so, are they included in the drivers here or must I load something from ASUS?

      Reply

    • CarvedInside    16 Jan 2015 @ 13:31   

      Don’t know what you mean by MDB HDMI. I don’t have any experience with HDAV cards so I can’t be of much help. Maybe someone with a HDAV card will jump in and help out. I’m not sure what exactly is the problem, the HDAV HDMI input does not work or/and HDAV HDMI output doesn’t? Maybe you should try with the original Asus drivers ( v1794) and see if with those drivers the cards HDMI output(?) works.

      • TomP    16 Jan 2015 @ 13:53   

        Sorry, it was a mistype. It should be MBD = motherboard. Help would be appreciated.
        If it helps, control panel offers me 2 sound options for the “ASUS Xonar HDAV Slim Audio Device” but selecting either of these make no difference…
        – Speakers
        – SPDIF Pass-through Device
        Do I have to remove the UNI Xonar drivers to install the ASUS ones? and would I have to uninstall the ASUS to get back to UNI Xonar?

        Reply

        • CarvedInside    16 Jan 2015 @ 14:24   

          Yes it is recommended that you uninstall the UNi Xonar drivers before installing ASUS ones, the same rule applies going from ASUS to UNi.
          Let me know if with ASUS drivers HDMI output works.

            Help. The UnI Xonar driver uninstall has been stuck for 30min and nothing is happening – any thoughts?

            • CarvedInside    16 Jan 2015 @ 20:34   

              The uninstall process take less than 1 minute. End task the process if it’s stuck. Restart and try uninstalling again if the entry is still in Programs and Features. If it gets stuck again then you can either try a driver clean like it’s presented in FAQ Q&A1 (steps 2-3) or just install the ASUS drivers.

                I did that, thanks. Installing the ASUS drivers made no difference, still no HDMI output. Ideas welcome.

                I contacted ASUS support and they suggested disabling the on-board graphics controller but is that not illogical as the card acts as a pass-through for the main graphics controller?

                  It seems so, and it is specified in the HDAV manual that you need both HDMI input and output connected, but as I said I have no experience with HDAV cards. Just to be rule out that it’s not a driver problem and that the original drivers have been installed correctly, check the Driver Version field from Device Manager Xonar HDAV card proprieties, it should end in 1794.

                  What I can say is that from the looks of it it’s either a configuration issue on your part (check that the cables are properly connected and you’ve selected HDMI Out like it’s described in Chapter 6.2 of the HDAV manual) or the Xonar HDMI output is defective. I don’t know what else to say.

    I have Xonar STX since 2010, and I found this driver very excellent, it sounds better than originally driver. I’m a audiophile since 1996. Thank you for your works.
    I don’t have any issue installing it, I’m in win7 x64.

      I’m happy to hear that. Thanks for sharing. Can you tell me which panel configuration have you installed with UNi Xonar drivers?

      Reply

  6. razafy    16 Jan 2015 @ 08:09

    @carvedinside
    Thanks for confirming all that I had already done, the driver version is correct, cables connected and the HDMI out selected (this is only a sound setting not video) – of course this was via the motherboard HDMI and I can’t check it via the HDAV HDMI as it doesn’t work.
    There seem to be no video settings in the ASUS panel and only sound output settings available in Windows (where I did select the HDAV Slim pass-through configuration too)
    I’ve run out of config options, so I guess there is something faulty and I need to return the card as defective. Thanks for your patient help and advice.

    Anyone have any luck installing the drivers for Asus Xonar DS on Windows 10 64 bit. I’ve right clicked on unknown device, browsed to the extracted drivers and select Xonar DS device. After trying to install the drivers I get “This device cannot start (code 10)”

    Hey, Xonar STX working on Windows 10 x64, but only through RCA and SPDIF outputs, the Headphones jack is not working. Anyone has a fix for this? Thanks

      Hi. Which panel are you using to switch to Headphones jack? you could try swithing with C-Media panel or XonarSwitch. If that does not work, its a driver issue and you’ll have to wait till newer drivers are available.

        Well… I forgot to switch to headphones. It was in 2 speakers mode hehe, sorry, my fault. Working perfectly in Windows 10!!
