    You both have stx that have plx bridge. The problem is cards with asmedia bridge. Asmedia is an integrated circuit design company owned by Asus.

        I have a qestion…

        If i have installed my STX (1) on my Board (ASUS X470 F Gaming) my PC start 2 times (only on coldboot).

        (Pc starts, after 1 second it turns off and reboot self after 2 seconds)

        If i have the Soundcard not installed the PC coldboot is fine…

        Is this normal ?, becouse i think it can be the plx pcie bridge

          It’s an issue with the motherboard probably when there are other PCI-e devices plugged in. You could contact ASUS support to let them know of the problem.

            but it is only if i pull the plug from the system, its only the coldboot… after this the system always start without a “break”

    HW:
    Gigabyte X470 AORUS ULTRA GAMING (rev. 1.0)
    R7 2700x
    Asus Xonar D2X
    latest unixfi drivers
    Windows 10 LTSC 1809, Windows 10 1903

    => Instant reboot after playing audio. If i play audio right after reboot and continue to do so, pc keeps running. If you leave it alone and don’t play audio – 99% of the time system hard resets. I am also missing the click of the relay, which the card does on every powercycle, after waking the card up from possible idle (long time no audio)

    can get quite frustrating if you forget that and “just want to turn on some music” and all your vms and open work just closes out of nowhere… Did i mention to better disable all windows sounds? An error sound could crash your pc 😀

      Thank you for the info. If you can, please take a screenshot of devices and their IRQ (guide here) and send it to me via e-mail or upload it somewhere(imgur,imgbb, etc.). Only those (PCI) entries are important and make sure that all (PCI) entries are included in the screenshot.

      Have you tried any of the possible solutions presented in the post above?

        Hi CarvedInside,

        tried all solutions i found on the internet, including yours 🙂
        Here is the requested IRQ pic. The card works best in second pcie x16 slot. IRQ is not shared.
        https://ibb.co/WHsh6Jk

        ATM it seems pretty stable. I am on vacation the next days, maybe i’ll remember to get back here and post my current bios config.
        Last changes i did:
        – changing the psu settings from auto to “new model psu”.
        – Turned of XMP (3000MHz) to custom 2933 Mhz ram clock.
        – SMT and SVM still active as i need these features.
        – onboard sound is disabled.
        – HPET active as my applications perform way better with it enabled.
        – Forcing a specific PCIe version made it worse so its back to auto.
        – F42 BIOS too bad they removed PCie v4 support in this version – but with this kind of issues you update and hope for the best 😛

          Thank you. Which UNi Xonar driver version you have now installed? If it’s v1.71.1, could this be what resolved or mitigated the issues?
          Any information that might be helpful for others is welcomed.

    I’m using a “ASUS ROG STRIX x570-E Gaming”-Board with a Ryzen 9 3900x and installing my good old Xonar D2X in a PCIe-x1 Slot always results in an instant reboot at the drivers installation (1825 v1.81a r2).
    Except when I put it in the second PCIe-x16 Slot. It works there but then my Graphics Card runs only at PCIe-x8. So that’s not really a solution for me. Putting it in the third long PCIe (4x, 2x) is stopping the pc from booting at all.
    I hope this won’t be the end of the D2X, I got it for nearly 10 years. using onboard meanwhile, which is not even remotely as good.

    • CarvedInside29 Sep 2019 @ 22:51

      Thank you for the information. According to these benchmarks you would only lose about 2-3% on a RTX 2080Ti when going in a PCIe 3.0 x8, lower performance cards than that will lose even less. I think it’s definitely worth it if you can still use the Xonar D2X that way.

      • Sascha30 Sep 2019 @ 07:56

        I did exactly that after 2 days of onboard sound. It’s so good to hear the familiar quality again. And of course you are right and I knew that I would not notice a difference in performance in everyday situations….it’s just an itch in my brain. I just upgraded my pc after 10 years and now I can’t use it at peak efficiency. that’s somehow very annoying to me and I think about updating my soundcard too. I guess hoping for a bios / software fix is not really fruitful? But where would I go? I still need analog 5.1 output.
        Well. For now it is working.

        • CarvedInside04 Oct 2019 @ 02:56

          Let us know if run into problems while having the D2X in the 2nd x16 slot.
          Well, probably only other option is a Creative Sound BlasterX AE-5 or better, but as you can see here, that also might not work.
          I would not be hopeful for a solution. It might not be possible for me or anyone else in community come up with a fix. On the other hand, ASUS does not care solving these issues. Unless there is significant community uproar towards ASUS, they won’t do anything.

          For v1.80a and STX II cards you need to download this patched version of Asus Audio Center and copy paste it over “C:\Program Files\UNi Xonar Audio\Customapp\”.

            I tried the UNi-Xonar-W10-1825-v1.81a-r2.
            With this one the Control Center worked properly but when i switched from 2 Speaker to Headphones i had an immeadiitly crash.
            After reboot it worked fine a couple of trys to change fp and rp but than crash again.

              When it comes to your problem, changing between different drivers won’t do much, except maybe v1.71.1 drivers. You will have to try the possible solutions, particularly no. 4 and no. 3.

    Hello to all. I have the MSI X470 Gaming Plus. I recently became the owner of Xonar DX. After installing the drivers, the card confuses the channels. Any channel can play from any speaker. (I have 5.1 JBL-631). Tell me, is this a problem of incompatibility between the motherboard and the sound card or is there a problem in the card itself and is it faulty?

    Reply

    • CarvedInside17 Oct 2019 @ 06:08

      In your case the problem might be from the Xonar DX. Check the instructions that I’ve written at FAQ Q&A 20. Let me know if that fixed the channel problem and if the card works fine or there are other issues.

    Essence STX II is not working on MSI X570-A PRO.

    Known good card (was being used prior to system upgrade). Running on latest BIOS, have attempted a clean windows install, and switching PCIe slots / speeds. Regardless of configuration, any attempt by windows to use the card (including installing the drivers) results in an immediate system crash.

        I have now. Whilst the 1.71.1 drivers haven’t presented any crashes, I cannot get any sound from the card through the heaphone output (and lack the means to test the other outputs).

    Hello everyone, today I bought Asus STX II 7.1, put it in my “PCI_E5” slot with this configuration – AMD R5 2600, MSI B450 Tomahawk, flashed with the last BIOS, reset BIOS settings in advance. The card works stably with official drivers and the UNi Xonar W10 1825 v1.81a r2, the devices switch normally, there is no blue screen. I am glad.

    Biostar X570GT8: Xonar DGX works flawlessly with all Bios versions up to including AGESA 1.0.0.3ABBA/910. With the AGESA 1.0.0.4 Beta Bios the system does not post and the post code LED shows code 97: “Console Output devices connect”. Tested with both a RTX 2080 and a GTX 960 as GPUs.

    My guess: The mainboard tries to use the soundcard as display output. No idea how to change that behavior yet, chipset or CPU lanes make no difference.

    • CarvedInside30 Oct 2019 @ 22:11

      Look in your BIOS for option called “Initial Display Output” or similar, this would allow you to select in which PCIe the main video card is plugged.
      You should contact Biostar and let them know of the situation.
      I am wondering if it’s because of changes that AMD made to AGESA 1.0.0.4 Beta or it’s because of other changes Biostar made to their BIOS. Guess we will see if others report similar issues with other motherboard.
      Keep us updated.

      • Stahlkocher30 Oct 2019 @ 22:57

        I was not able to find an option to set the video output. What I found are options for legacy/UEFI modes. Soundcards seem to start in UEFI mode by default, GPUs in legacy. My GPU does not support legacy, but well. Biostar’s BIOS is a mystery at times.

        I will have some time tomorrow to experiment a bit more.

          Look for Chipset->Northbridge->GFX configuration->Primary Video Device. In the manual it shows it has only options: NB PCIe slot Video (Default) / IGD Video. If even with this new BIOS it still only those 2 options are available, might be worth a shot setting it to “IGD Video” if it was set to “NB PCIe slot Video (Default)” or viseversa, and try it with Integrated Graphics being set to “Auto” and another time with it being set to “Disabled”.

          • Stahlkocher31 Oct 2019 @ 23:56

            The manual is sadly not even remotely comparable to the real BIOS. The current Beta Bios at least only got the Gnb Hd Audio option and the PSPP Policy options available, the other four options of the GFX Configs menu are removed.

            I just checked the 1004B Beta against the 1003ABBA Bios which I still got installed on the second BIOS chip and the Abba Bios also lacked these options already.

            I wrote to the Biostar support and will see if they fix the BIOS. If they don’t I will either have to see about modding the BIOS myself or, if I decide that I do not want the hassle with always modding the BIOS again when a new one comes out, returning the board as defective.

                Have you tried setting “Initial Display Output” to the PCIe slot in which the main video card is plugged?
                Tell us the full name of the motherboard and which Xonar card you have. Did it worked fine before?

                  While Gigabyte managed to fix the 1004 BIOS for some boards to restore compatability with add-in cards like soundcards, Biostar did not manage to do so with the final 1004 release BIOS.

                  Still no boot with the Xonar DGX.
