Interesting. I also have an AMD CPU (AMD 7950X3D). I use process lasso and give OBS high priority. I also run it as admin and write to an NVMe SSD. Would be interesting if this was an AMD related issue.

I had this issue before on my old setup but after upgrading to a new PC, it hasn't showed its head yet, even after a OBS session for 2-3 hours.
The main difference are:
Intel 6th gen to Intel 13th gen (and new motherboard etc etc)
More ram then before, changing to newer DDR standard.
Windows 10 to Windows 11.
It's possible sample rate settings has changed with audio devices & OBS, since I installed Windows from scratch.
I reckon this is really broad information, but I reckon it'd be useful to document regardless.

TLDR: Try changing the Sample Rate & Bit Depth in the Windows Sound control Panel to a lower setting. Windows usually defaults to something like "2 channel, 24 bit, 48000 Hz (Studio Quality)", the frequency being 48000 Hz. Changed mine to 44100 Hz and haven't had an audio issue since.
As of May, I have a similar setup to @Mundayy and @dan.cormack - AMD 7950X3D, Asus X670E, DDR5 64GB RAM, 2x Samsung NVMe SSDs, RTX 4080, Win 11, stock settings with no overclocks. Previously, I had an Intel i7-7700K system with DDR4, GTX 1080 and wired USB headphones, with the default sound settings I never ran into this issue. However, with my new AMD PC build, games like Red Dead Online, Cyberpunk 2077 and Jedi: Survivor would all kick in with this audio issue after a few minutes of play.
I'm not 100% certain but I think it has something to do with the timing frequency of the audio device you're using for playback. In my case, I'm using the Corsair Virtuoso XT wireless headset. It defaulted to the 48000 Hz frequency I mentioned above. I singled out software updates, drivers and third-party utilities to ensure it wasn't something else being introduced to my machine.
For my setup, I use iCUE software to manage the mouse, keyboard and headphones. Having iCUE installed or not made no difference here, even with the default headphone drivers Windows fetches this problem was still happening. Finally, I made these changes in Windows 11 to fix the issue for my setup:
- Close OBS
- Open Windows Settings > System > Sound
- Scroll down to the Advanced section and choose "More Sound Settings"
- Find your default playback device on the list (green circle with white checkmark) double-click it to open properties.
- On the Advanced tab, note the current setting listed under "Default Format". Use the drop-down to see what other options are available, switch to another 24-bit frequency with a lower value. Press Apply & OK.
- (OPTIONAL) Check to see if you need to make any changes for the default communications device as well, if it's not also the default device. (green circle, white telephone) If it's not shown, your default device is also the default communications device.
- (OPTIONAL) You may want to change the default setting for Windows communication detection, which can lower the volume of your other applications while on voice calls. To modify this, switch to the Communications tab and choose the "Do nothing" option.
- Re-open OBS, try your game again to see if the audio issues continue.
Good luck!

The data corruption happens before* the process_audio_balancing() called:
With balance shifted to R channel (balance applied in the Advanced Audio Properties) at "crackling" part of the track I see this:
both the audio test signal (1kHz sine) and the "crackling" were reduced by similar amount on the L channel (L is top in the screenshot)
Edit *of course if there is no some magnificent random multiplier that applies somewhere later and only to the Application Audio Capture (BETA)...

Who want to "test" MS native solution (there are rumors that Windows itself has "crackling" issue, so nothing to blame OBS for) can do next:
Main route:
github.com
Other route (simpler to use),
similar build of the MS native solution will be here (for about 30 days, as building artifact):
ci.appveyor.com
use this cmd file ("proc_capture.cmd"):
github.com
In short - this is small cmd line util from MS itself (about 50KiB) to record audio of any .exe process to .wav file (uncompressed). If there is "crackle" in the recorded .wav file from this util - feel free to write to MS support.

First row of the cmd file: specify app executable name to capture audio from.
Second row of the cmd file: specify destination folder for .wav recording (this is location of the ApplicationLoopback.exe itself).
Don't forget to save changes.
proc_capture.cmd should be placed next to the ApplicationLoopback.exe (i.e. in one folder, default location "c:\appac").
Recorded "Captured.wav" file will be overwritten without confirmation!!! So, rename it manually after record finished (if needed).

Hello to you all.
Ive been watching this forum for a while.
I run into the same problem once time back at least (half year back)
When i start up streaming on twitch, everything goes well.
When i ran up into OBS win-audio-capture - the audio start crackling and beeing on total catastrofic quality.
Even after that the same issue starts on Discord streams... simply everywhere.
Once i ask some guyz im my close range.. they told that the Windows made an update on win 10 where they put some audio differences (in gamemode scenerio) so the audio between AMD CPU and Windows got into problems.
The problem is.. even if i fully unninstall win-audio-capture - the problems still standing.. the reinstal of OBS with full reset did not work as same as reinstalling my entire PC..
Is there anything to do?

@OnlyMeDarK make sure that the issue is caused by software and not by faulty jack. Then follow the steps (see above) mentioned on github pages. And sometimes virtual devices can solve the problem mentioned in this thread.
