Audio crackling/popping when I interact with Windows10

I recently started having an audio issue a few days ago, where when I have music playing (either on Spotify or Youtube) and I open the Windows Explorer to view files, open an application, hover over buttons or folders in the Explorer, or do anything on my computer, the audio sometimes pops and crackles, reacting to my mouse movements/actions. It also happens when I'm only listening to music and not moving my mouse. It will crackle maybe once every 2-3 minutes. I've gone through several websites and conducted steps to diagnose my problem, such as:

• updating my audio drivers (no new updates found)
• removing any sound effects on my playback device
• changing the default format on my playback device (tried most options)
• turning/replugging/cleaning/fiddling with the output jacks (I have a front and a rear 3.5mm jack and both of them crackle through my speakers and headphones)
• reviewing DPC latency/audio processing latency checks via LatencyMon (no issue, got the green light)
• reviewing overall CPU/memory/GPU usage (CPU and GPU are single digits and memory is around 30% because of browsers and other caches)
• moving any possible interfering tech out of the way (closest objects are my monitor and keyboard + mouse)
• "power drained" my computer (shut down, turn off PSU, unplugged everything, hold down power button for 20 seconds)

The only thing I can think of that changed with my computer is that I swapped out my graphics card (from a GTX 980 TI to RTX 2080) about a month before the crackling started. I didn't touch anything around the audio jack pin connectors and the PSU supports the increase in graphics processing power.

I'm out of ideas to try, so I'm hoping someone can give me some further advice.
