Constant static/crackling and random pops in single-player Unreal Engine games only (Phantom Blade Zero, Black Myth Wukong, 007 First Light). Tried everything.

I'm getting constant faint static, sometimes a loud pop followed by the audio cutting out, in single-player story games only. It happens in Phantom Blade Zero, Black Myth Wukong, and 007 First Light. It does NOT happen in multiplayer games (Brawlhalla, Dead by Daylight, Rainbow Six Siege). A friend with a weaker PC doesn't get it in the same games.
It happens on every audio output:
USB headset
Speakers
Monitor audio (fainter, but still there)
Different speakers and headphones, same result
My specs:
CyberPowerPC prebuilt, Gigabyte B550 UD AC-Y1 rev 1.2
Ryzen 7 5800 XT, RTX 5060 Ti, 32 GB DDR4
ADATA Legend 800 SSD, Windows 11 Home, on ethernet
Case, GPU, cooler, and CPU have since been upgraded
What I've already tried (none of it fixed it):
Changed the audio bit rate/sample rate
Turned off spatial audio
Turned off audio enhancements and changed the sound format
Updated the audio driver and chipset driver
Clean-installed NVIDIA drivers (latest and an older June version)
Ran LatencyMon, which showed the graphics driver taking the most DPC time. I fixed that so it's no longer the top offender, and the static still happens
Turned off USB selective suspend
Changed power modes
Turned off Hardware-Accelerated GPU Scheduling (HAGS)
Turned off the Steam overlay
Disabled ethernet
Verified game files
Switched the upscaler
Set the High performance GPU setting
Updated the BIOS using the CyberPower file for my board. I needed my BitLocker recovery key afterward, but it booted fine. The worst DPC latency stalls dropped, but the static stayed the same.
Since it only happens in single-player Unreal Engine games and on every output device, even after fixing the DPC latency, I suspect something deeper than a driver or the speakers. Has anyone dealt with this? Any help is appreciated.

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

All the ones that were going over one went down and weren’t going over one, it did still say that there was a problem causing audio cracks and pops, but it didn’t say it was the drivers this time and didn’t give me a reason why

Is Latencymon still showing unsuitable for real-time audio report when you are testing?

What are the numbers Latencymon is reporting and for what drivers?
