      Which drivers have you tried? Does your STX II card work with original Asus drivers?
      If it does not and it’s missing from device manager even as unknown multimedia device then your card probably is defective.

    Hi, have a problem here!
    When i starts the pc, with UNI Xonar low latency and XonarSwitch, with two recording devices connected (line-in and mic), only line-in is avaiable, but mic not. Is strange cos with my realtek integrated i did not have this problem, i could use both.

    Hello, my problem is: Ive connected 2 speakers to the front panel and mic directly in souncard (Xonar DX). When im trying to listen to music – sound from speakers is detecting by a mic. Tried to connect some headphones in the front panel – same result.
    Final result – any sound that i try to listen through the FP (speakers or headphones) playing in the mic.

    Hello, I’ve had issues with my Xonar Essence STX for as long as I can remember since the early windows 10 previews. HTML5 videos have their sound stutter when played using Google Chrome. It doesn’t happen with Edge/Internet explorer.

    What could be the cause? If it’s driver related, can it be fixed? Also, is it a known issue? Thanks in advance for the help.

    Hi guys

    i have a Xonar D2 and an 5.1 system Philips Hts 5540 and i connect the two through a coaxial cable
    My question is in coaxial do i use the hts 5540 dacs or the Xonar dacs?
    IF it is the Hts 5540 dacs is there a way i can use the Xonar dacs through coaxial?

    P.s: The 5.1 system has only coaxial in and stereo in so i cant use three 3.5mm jacs to connect the soundcard

    Thanks for the help!

      With Coaxial or S/PDIF you use the Philips HTS 5540 DAC. It isn’t possible to use Xonar DAC with digital connections (coaxial and S/PDIF).

    Hello All,

    I would like to know how to make my Essence ST with H6 board output 2.1 stereo with Bass Management Enabled (as in i have 2 front speakers on Left and Right RCA’s and separate Sub Woofer connected to H6 board’s sub output RCA) so that when i watch 5.1 Movies/Games the voice isn’t on the Center speaker but front Left and Right speakers and Sub Woofer still plays all the low frequencies…

    Thanks a lot Guys.

    Hello I bought and installed windows 10. I had problems with the on board sound card drivers so bought the xonar gaming card. It works great except I have sound every where but team speak 3. I tried a few things including installing your drivers. Any advice you can give me or maybe a work around?
    Thanks
    Bud

    Hello,

    Thank you for these great drivers! I have an issue though. For some reason the output isn’t recordable. I can hear audio fine but any recording program doesn’t record it.

    What might explain the issue is this: When I go to Playback devices > Playback I cannot see any green bars being filled when I listen to music despite hearing the audio. When I do “Test” it does show audio being played though.

    Do you know what can be wrong?

      You need to set 2 channels on Input and 6 channels on output of your audio panel (asus xonar or cmedia panel).
      Close the app before you change the setup, and after open it again.

    Thx for all your hard work!

    I just got upmix running again (after uninstalling v1.72 and installing 1.75a, even standalone wasn’t helping anymore) and everything is fine with that. BUT is there a way to stay on 6 channel output (to have surround in games & dvds) and at the same time have upmix enabled for stereo sources? Or do I have to manually change between these?

    Cheers & thx again

      I would also like to know if there is a solution to this problem, I know this sounds like a minor issue but it’s really not as it requires changing multiple settings depending on the program used for playback and on the desired output (headphones vs speakers)

      Fortunately my headphones are connected to a separate headphone DAC so any fiddling I do to the Xonar drivers will not affect headphone playback, but it does mean however that options are limited when it comes to enforcing upmixing in Foobar or MPC-HC as an error will appear when trying to render more then 2 channels on that particular stereo device.

      One solution for Foobar playback that does not require enforce upmixing via DSPs is by using the WASAPI output coupled with the “Re-enable stereo upmix to 5.1” option in the UNi Xonar driver installer. This will upmix any stereo files to 5.1 during playback on my speakers, will correctly render 5.1 files (L to L, LS to LS, etc..) and has the added benefit that it does not break headphone compatibility and will correctly output stereo files on headphones by simply changing the renderer.

      Of course, the above works only for Foobar, as playback from MPC-HC, Games, Firefox, etc.. will still not fill the unused channels if the drivers is set to the 6CH mode, and of course if I set it to 2CH, games, movies and surround albums stop working. I could enforce upmixing in MPC-HC, but that’s more of a hastle, and of course, it will break compatibility with headphones output, especially on movies with only 5.1 audio tracks as the mixdown will no longer be performed.

      It’s… really a hastle, and the fact that the drivers ARE capable of stereo to 5.1 upmixing even on 6CH via WASAPI makes me hopeful that a solution might be available for DirectSound.
      And before you ask, yes, I double checked in Foobar: DirectSound Speakers output is limited to Front L and R on stereo files, wheres WASAPI will clone the sound to the Rear/FC speakers, all other settings being identical.

    Any idea what’s going on here. I’ve had this problem since I’ve had the card. Sometimes after a fresh install of windows, I’ll install the sound drivers and the sound will be absolutely fine. But other times, like recently I’ve just gone from Windows 7 to Windows 10, the sound volume is reduced a lot, and music sounds quite shallow and a lot less ‘punchy’ – is the best way I can put it. When the sound is OK, I can play music at 3%-5% and it’s really loud and sounds really good, but when it decides not to behave, I have to set it at 20%-25% to get anyway close the same volume, but yet it doesn’t sound the same.

    In both cases I’ve had the settings the same, headphone gain on +12db. I’ve tried both official Asus drivers and Unixonar drivers, reinstalled multiple times, reseated card and swapped out 12v molex for a different one.

    It seems like it’s a power thing, like the amp isn’t getting enough power to drive the headphones. But I don’t undertand, because it can’t be a hardware problem when all I’ve done is reinstall Windows and not touched the card.

    Hello! I had a problem with the volume of the front right channel. Sometimes it reduce to very low lvl ONLY at right front channel and i need to restart my PC to get it back.

      I’m having the same issue, restarting the card from control panel fixes it. It gets quieter and quieter until only left channel works. Win 7 64bit
      If you can’t restart the card from device manager, go to sound playback devices, and disable speakers first. This operation will crash xonar audio center.

    I’m running the Xonar Essence STX on Win 10 64 bit.. I’d like to try the Uni Xonar drivers. What is the best way to uninstall the existing drivers and remove all the crap?
    Thank you

      Uninstall current drivers. Restart. Install UNi Xonar drivers with “Run driver cleaning before install” option checked.

        Thank you CarvedInside. It went smoothly and all sounds good!
        I’m using SPDIF out to a M51 DAC and Adam A8X powered speakers. The headphone option is from the M51 DAC to a Violectric HPA V90 Amp and Sennheiser HD800 phones.

          Glad it worked out smoothly and thank you for the donation.

          Regarding your setup I may have some advices. I’m not sure if you know but using the Xonar with SPDIF output is no different than using the onboard audio card SPDIF output or by connecting the M51 DAC directly to the USB port on the PC. Xonar STX DAC and op-amps are completely bypassed and there is only the digital signal (1’s and 0’s) that gets out to the M51 DAC. M51 DAC does all the sound processing. To actually use the Xonar STX card you would need to use the soundcard’s analog connections (like connecting the Violectric HP Amp to the card).
          Now the DAC and op-amps included in M51 DAC are probably better than those in Xonar STX. If you are unsure you could find out by testing each with Right Mark Audio Analyzer. You would have to check the Xonar STX analog output connected to the microphone input. For testing the M51 DAC you could either use the current SPDIF connection or the USB connection and connect a cable from M51 DAC output to Xonar STX microphone input. If you do these tests I’m interested in seeing the results.
