I just made an account to also state that I am also having this problem, I had this on my old setup including a I7 2600, 7970, Asus P97 (not sure which it was, but asus), cougar 700w psu and crucial 16gb ballistix ram, win 7( not sure if it really occured on win7 but definetely on win10)
 
New setup is
Asus maximus viii ranger
i5 6600k
gtx 1080 (was a 970 for some time problem still occured)
16gb HyperX fury ram
cougar psu 700w
Win10
 
Luckily in my case the problem seems to occur only once every month or so maybe even longer intervals, rarely in shorter intervals. I primarily encounter this when watching youtube videos and today it happend when I shut down my pc and got an error message, triggering the windows error sound. The issue comes close to causing hearing damage I think but luckily I am able to rip off the headset fast enough to prevent that so far.
 
Either way I am considering selling this soundcard despite its awesome qualities but can anyone recommend a soundcard that is able to compete with the STX? Maybe the creative ZxR? Also does this problem affect the STX II equally or does it occur less frequently on that card?

I can't test this because I rarely trigger the noise but for people who get it more often, do me a favor and try this:
 
Go into Power Options (I just go Start -> type power options)
Change what the power buttons do (on the left)
At the top click "change settings that are currently unavailable
On the bottom uncheck "turn on fast startup"
 
My Skype has been giving me errors on shutdown and apparently others have been getting this. One post suggested that disabling fast boot could solve that problem. This got me thinking, maybe this ****s with other aspects of our drivers? I don't know, worth trying and literally nothing to lose.

That's not it because I have a SSD so the fast startup is always disabled on my PC. As someone suggested I'll post my setup:
 
Asus P8P67 Pro
Intel Core i5-2500K
Nvidia GTX 980Ti
G.SKILL DDR3 2x8GB 2133MHz RAM
OCZ Vertex 460 120GB SSD
Chieftec 14CS 600W PSU
Windows 10 x64

Disabling fast boot both on W8.1 and W10 doesn't help with the issue, it was never enabled on my system that was running the DX.

So I had this happen again. I reported previously that it went away with windows 10 after I opened a crap load of new audio instances just to specifically look for this bug (literally hundreds). Now, it may be because of the anniversary update, which happened after I did my tests, but it could also be I just managed to be unlucky and not find it. 
 
It does seem to only affect the xonar sound cards with asus branded processors and not cards like the dgx with a cmedia brand processor. And it only affects the analog output, not the spdif output on these cards.

I'm using windows 10 64 bit and had this issue several time even with windows 7. I'm using the official asus drivers for my asus stx II + sennheiser hd 650. a few minutes ago it happened again since a long time. my ears are still ringing. I was using firefox and was watching a youtube video and wind forward to the end. that triggered the distortion. my ears are still ringing. that's not healthy. the only thing the eventviewer showed me shortly after is this: I don't know if it's related but now I'm scared again while watching youtube videos. this sound is so loud, I'm hitting my headphones off my ears within a splitsecond just to stop the sound by playing a mp3.

i have the exact same reaction, @evvil, i toss my headphones off and play a song to make it go away. i dunno, i might try to sell my card if this problem only affects the minority of us. maybe the new owner's rig wont trigger it.

I did not see this thread, wish I had sooner. I get the same problem with a Xonar DX. Does anyone know how to recreate the problem consistently? And has anyone tried disabling Intel SpeedStep? It's been a good while since I had this problem and the only change was turning off Speedstep on my ASUS P8Z78-V Pro's BIOS. I'm not saying turning off SS worked but it's seriously been at least a month since I had it I think. I'd still like to solve it permanently somehow though.

 

[evvil]

Hello,
 
I was not able to recreate it by now. I was using firefox, windows 10 64 bit, youtube and I fastforwarded a youtube video. I've tried it several times ofc without wearing my headphones but was not able to trigger it again.

No screeching for me since june, last tricks I tried were disabling C6 state in bios, and core parking in Windows (https://bitsum.com/parkcontrol) + setting the soundcard to 192Khz.
Those settings may affect DPC latency and help with this issue. I admit it's quite random, but it's worth a try.
 
It was quite easy (5-10min) for me te reproduce this bug by skipping madly a html5 youtube video with Firefox - which seems to be a frequent trigger for a lot a people. I also use a little plugin to force Youtube to play video in flash.

Still was not able to trigger it again but one thing for sure. I'm still kinda scared back in my head while watching any youtube Video.

 

[evvil]

Aaaaand it happened again. Can't find anything in the event viewer but who cares, I'm deaf anyway.

yea im thinking of selling mine and just staying away from all ASUS products. this is not how you treat your flagship product(s).

For @evvil and @Aray:  As I reminded @racofer and @kittinzaa in Post 264, the problem is an incompatibility of the C-Media® CMI-8788 with the Vista audio stack; even ASUS® engineers have been hard-pressed to replicate the 6 kHz scream that I encountered on rare occasions in Win 7, and the Microsoft hotfix didn't address the issue for everybody.  I transferred my XONAR® STX to a LinUX box prior to dist-upgrading the ASUS® CM1630-06 from 7.0.8001 to 10.0.10586 and have zero problems with ALSA snd-virtuoso in Ubuntu® 16.04.1-LTS (LinUX Kernel Family 4.4).
 
I have found the XONAR family perfectly safe to use in any LinUX system with the driver snd-virtuoso in ALSA 1.0.27 and later.
