    I have a problem which started couple versions back then went away without any logical reason. When I boot up my PC I can’t get any sound but the volume bar in windows shows that in fact the sound is processed. When I check device manager I can see two Asus Xonar D1 Audio Device, one with yellow exclamation mark. The only thing that helps is to turn off an on Asus Xonar D1 Audio Device without an exclamation mark but I have to do it every time I boot up the system. Tried reinstalling drivers, remove them, clean registry and this time the problem persists. Win 8.1 x64

      I’ve never seen this before. Really strange. What’s it say under Device Status for the Xonar card with the exclamation mark in Device Manger? By turning off you mean disabling it Device Manager? And what happens to the one with the exclamation mark, does it stay the same?

        This is what I did to fix this: disabled device with exclamation mark and the sound was gone but after rebooting everything’s back to normal and I can see that second device disabled in the manager. Is it possible that my D1 is damaged? I remember I had the same problem on win7 some time ago. The device status is “this device cannot find enough free resources that it can use. Code 12″ Really strange.

          That was what I thought of suggesting to see if it fixes things.
          I would be more inclined to think this is a Windows problem that would go away with a new Windows installation. But if you had the problem on Win7 then that might not be it. It is possible that the motherboard is at fault, make sure you have the latest Bios installed and you could try different PCI slots.
          Maybe you can check your card in another PC (maybe go to a friend) and see if you get the same issue. If you get the same behavior then there is probably something wrong with the card. If not, maybe the motherboard or Windows is the issue.

          This is a long shot, but you could also check if you EEPROM wasn’t overwritten.

            Thanks for help, I will look into EEPROM situation today and try to switch to a different PCI. Cheers

                So EEPROM is OK. Surprisingly after changing slots the the card doesn’t work at all. Even LED doesn’t light up. But when I switched back everything’s back to normal and I don’t see cloned device in the manager (maybe cleaning the dust in my PC helped?). I’ll let you know if it comes back. Cheers

    Hi, I submit a bug in the drivers (Uni Xonar) on the Asus Xonar D2X error occurs in the form of waves and strong at a time when the rumbling bass work I tried to set the function 5.1 Flexbass but nothing, channel or DTS Dolby technology does not change anything , but the problem disappears as 2.0 or 4.0 of the Act or disconnect the cable from the equipment Center / Sub, I returned to the normal drivers, and there is no problem when installing the panel chose C-Media with activated GX Mode.
    He asked me to repair the error because the mods drivers seem to be a much better option, especially due to the C-Media Panel and reduced use of system resources.

    My system is Windows 7 x64

    PS. Sorry for my english but I’m Polish

    Yours

      It’s really hard for me to understand what you wrote. Are you saying that you have a problem with bass coming from subwoofer or center speaker? And that you only have the problem when you install the UNi drivers with C-media Panel (GX enabled) configuration?

      Have you tried installing the UNi drivers with C-media Panel without GX? Have you tried different drivers, like 1.64 for example? Try those if you haven’t.

    Hello!
    First I want to say thanks for the drivers, I’m overall very pleased with them and the sound is great with my STX II card but I have one very strange problem. It’s pretty complicated and a video describing the thing would probably be better and since english isn’t my native language this could get messy, but I’ll give it a shot anyway and hopefully you will understand what I’m trying to say. I will be as thorough as possible so that you may be able to address this problem.
    The problem occurs when I’m listening to FLAC files in winamp, not all songs but quite a few, not in VLC though, so I think this is specific to winamp (hopefully). So, on to the problem; when listening to any of these specific songs I get crackling noise whenever I skip in the songs (move the slider with mouse or keyboard arrows). So far everything is normal except for the crackling, but when I open the UNI Xonar interface and choose Effect and change the equalizer from it’s default state to anything else (presets or just changing one of the bars up or down) the sound completely dies. No error message just completely quiet. This only happens after the crackling sound or when I close winamp, as long as I just let the songs play it’s fine. If I then set the equalizer to default the sound comes back, but if I want to use the equalizer in any other state I have to “reset” the soundcard by changing the analog output to something else and then change it back, i.e. from 2 speakers to headphones and back again. Then everything is back to normal again and I can use the equalizer, until I play one of the songs in winamp again. I have also got two blue screens connected to these crackles, the usual Windows 8.1 bluescreen with a message that says something like “driver_QRL_not_less_or_equal_STXII”, not sure about the QRL but something like that.
    I’m using Windows 8.1, STX II soundcard with Uni Xonar drivers 1.75b, 2 channels, PCM 44.1 Khz, everything else default except the equalizer as stated above, no microphone connected, Winamp v5.666 with allow 24bit enabled.
    I think the problem has gotten worse the last few days or maybe it’s just because I haven’t played those specific songs in a while or just didn’t notice it before. When using my speakers the equalizer is on default so that could be why I haven’t noticed it since it works fine at default. When I’m listening to my headphones I change the equalizer and that was how i noticed it. Maybe it could be after some recent updates in Windows or maybe it has always been there. The computer is approximately 2 months old.

    I’m not experiencing any other problems with the soundcard, everything works fine in games etc. with the equalizer enabled, I haven’t tried any other drivers for this soundcard or any other versions of winamp yet so I don’t know if this is consistent with any other versions, but since this happens to me it could be of interest for you to try to replicate this problem and maybe find a fix (for future versions). Sorry for the long post but I hope it makes sense and that you get back to me. In the meantime I’ll try a different version of Winamp to start with and then maybe some other version of the Uni Xonar drivers, I could also try the official drivers and see if the problem occurs there also.

    Best regards
    Andreas

      Hi Andreas which output plugin do you use in winamp? Try to increase latency/buffer size in output plugin settings. I use Kernel Streaming ouput for my Winamp and experienced the same issue. But after increasing the buffer size one step in the output plugin its completley solved. If u are not using any Kernel Streaming Plugin i suggest u use the directsound output so go ahead and try increasing lateny / buffer size within the plugin and see if ur problem is solved.
