The 1.75 drivers come in two variants:

1.75a

      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.
      Now, if you are using a NoScript browser addon then you should disable it so that reply to discussion button works correctly.

      It was a problem with the driver installation that did not apply the correct audio settings for the cards (e.g. to fix surround echo).

      Hi, thanks for creating this driver, Asus should pay you for their incompetencies…everything works great, the bass is really good with this driver and nice to see 24bit/192khz output. The original driver from Asus did not have that option.

      The Xonar application is useless it seems and colours the sound too much. I am experiencing a problem right now tho. I’m running Win7home premium, using SPDIF to DAC works fine when I check off the PCM box in the Xonar App. However, I cannot switch to the analog line level out for the front L/R speakers that’s plugged in already. So my setup is this spdif is for hifi listening through my amp. Line level for crappy computer speakers. The line level analog connector does not work. Is that driver issue as well? This even after I disable the spdif connection.

      Any help is much appreciated.

        You’ve replied to someone else’s comment. In your case you should have made a new comment.
        Analog line out not working could mean there is something wrong with your card. Be sure that the computer speakers actually work, try them with onboard audio. You could also try re-installing UNi Xonar drivers or try a different version just in case something went wrong with the installation but this is highly unlikely. If your Xonar card doesn’t have warranty anymore you could try to use the Rear jack instead of Front jack for speaker out by configuring the drivers to allow stereo upmix (see FAQ Q&A4).

    I have a problem with the latest releases. I have windows 7 with TWO ASUS Xonar cards, a PCI essence ST card and a PCIe STX II card (non 7.1). Previously i have been running the UNi Xonar v1.72 & the official STX II drivers. BOTH cards worked fine. Now i am running the UNi Xonar v1.75b rev.2 & UNi Xonar v1.75 drivers. No matter what i do only the old essence ST card works now. The new STX II card doesn’t register in control panel or anywhere even with just the rev 2 driver installed. Anything i am doing wrong here?

    • CarvedInside    24 Oct 2014 @ 16:23   

      Does STX II card show as installed and working in Device Manager? When you say they were working fine are you saying that you had 2 Asus/Cmedia panels one for each card and now you have only one and it’s only working for the Xonar ST?

    I tried to install 1.75b2 on Windows 10 with Test Mode enabled, but says to plug-in my xonar device. I have Essence STX.
    1.75a Works fine.

    I now have my HDAV Slim 1.3 and see there is a “HDAV HDMI enabler v1.0″ in the Add-Ons list. Do I need this add-on as well as the 1.75a drivers? and what does it do?

    Reply

    • CarvedInside    26 Oct 2014 @ 19:34   

      “HDAV HDMI enabler v1.0″ is a standalone application and not a addon. I made it case HDMI options would not show in the Asus Xonar Audio Center for HDAV cards and UNi Xonar drivers. I don’t think you’ll need it.

    The New drivers(the one that requires test mode on older cards) fixed some problems on my Xonar DX(using analog). :D

      Well i should really say what it fixed, it fixed the Upmix problems i’ve been having in conjuction with K-lite(i dunno how this got fixed by a driver update). And C-media panel now opens the actual window instead of first opening and putting it on the taskbar(which made it real awkward)

    Thanks for the new driver. I have a Xonar STX and with the drivers 1.75b in the section info in ASUS control pannel ASIO version results: N/A. With foobar2000 I can use ASIO at 32 bit but if I switch to 64 bit results a error: “Unrecoverable playback error: Could not locate the specified virtual ASIO device” with previus version worked fine, i think there are an issue in the installation.
    PS: sorry for my english

    Just a word to thank you for your work! I had several troubles with the official Asus driver and Xonar STX on Win7 64bit and Asus audio center, and the drivers are no more updated for win7. With your driver version, I have no more problem, sound is great and much better than before! Wonderful!
    I have installed UNi Xonar v1.72 for now, since several comments reported issues with 1.75 and 1.75b, but will catch future updates. Thank you!

    Is it posible to make updated ASIO for old xonar cards(ST and STX)?

    Thank you for making UNi Xonar Drivers!

    Hi there Carved.
    OK. I just uninstalled all previous drivers. Did a clean fresh “UNi-Xonar-STX-II-11.5-v1.75b-r2″ install with normal asus audio centre option, cleaning before install and i picked the xonar essence STX II card from the drop down field. During installation one of my two cards clicks audibly. Hard to say which one really. After installation it says “ASUS Xonar Essence ST Audio device” in the windows 7 (x64) control panel which basically means the STX II 1.75b driver only installs my Essence ST (PCI) card. The STX II (PCIe) doesnt register anywhere. I have the basic ASUS Essence STX II that comes without the 7.1 daughterboard. Previously the STX II had the grey ASUS audio centre icon in tray with the official drivers. And for the essence ST card i had to manually click the blue uni xonar 1.72 icon. For some reason both tray icons and applications could not exist at the same time. Happily providing you with all the info you need. And thanks for the hard work!

    Update: I have them both running now. The STX II installs fine via device manager driver update, and then navigating manually to the UNI driver folder. At first it will say “device status:
    Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)” for the essence ST card in device manager. And when i install the “UNi Xonar 1816/1822 v1.75a r2″ after that i get them both running. Happy happy joy joy :D

      Update 2: It seems like i can only have one Asus Audio Centre installed at a time. So every time i want to use the STX II card i have to reinstall the driver to get the proper audio centre. I love switching between both cards since they have different voiced OpAmps on them.

      Reply

      • asdf    28 Oct 2014 @ 17:32   

        Suggestion…. is it possible to make the STX II audio centre a different colour to indicate its the second gen card like asus did with theirs?
        Talking about the tray icon/colour.

      • CarvedInside    29 Oct 2014 @ 20:16   

        Might want to try this: assuming the last drivers have installed are 1.75a, go to Asus STX II original drivers and search for CustomApp folder. Copy it somewhere else (but don’t replace the CustomApp folder in Program Files\UNi Xonar Audio\), then from where you copied it, rename AsusAudioCenter.exe to AsusAudioCenterSTXII.exe. Try launching the AsusAudioCenterSTXII.exe, try it with the AsusAudioCenter.exe from UNi Xonar CustomApp (or the Start->Programs->Uni Xonar shortcut) running and if that does not work then try with AsusAudioCenter.exe closed. This method should at least let you have control over one of the cards without installing the drivers over and over.
