Alerts Break Volume

Hello, everyone!

I have a tricky problem that I have been trying to troubleshoot for the better part of a month now. Whenever I'm playing anything even slightly GPU intensive (above 50% GPU usage), alerts will start breaking and will usually end up being complete white noise.
I will attach a short recording of this happening in Witcher 3, where I was hovering around 55% GPU usage.
In the video underneath here is me opening up the game, loading in and immediately testing a Cheer alert. Beware, sort of loud because of the volume breaking.


I have been able to successfully reproduce this issue with games like SIFU, Pacific Drive, RoboCop, Dark Souls 3, and many more.

My rig is:
9070 XT
32 GB 3200MHz DDR4 RAM
i5 13600KF (not overclocked)

What I have tried so far, includes stuff like turning off HAGS, turning down game settings (helps a little bit for a while, but not indefinitely), made sure OBS runs as admin - which it does by default, made sure my drivers are up-to-date - which they are, and a ton of Google-fu which so far has yielded nothing that helped.

At this point, I'm rather stumped and I'm therefore here seeking advice.
If anything else needs to be added, feel free to request whatever it is you need.

Edit: Important to mention, I guess, that this does not happen if I'm doing things like playing emulated SNES games or using my DOSBOX, so it appears to be tied to my GPU. I just can't understand why it happens at half max-load.

I finally figured out what it was.

On the off-chance that this helps someone down the line with a random google search, I had the same audio bug happen to me when I joined a Discord call after turning on my headset and switching audio input device in Windows.

Turns out that it was the "Audio Enhancement" setting on my Razer Blackshark v2 headset causing the problems, as Razer's synapse software that handles the THX Spatial Audio (virtualized 7.1) processing does not play well together with OBS. Turning off enhancements, and thus the THX Spatial Audio (I also ticked it back onto Stereo), completely solved the issue.

I have filed a bug report with Razer about this, as I believe this is a problem on the driver-level with Razer Synapse. I am unsure what is the root problem, maybe the driver's bandwidth on audio-in gets overloaded or it just does not like OBS handing it browser source audio. Who knows.

In any case, case closed.
Try turning off audio enhancements.
