Ambient audio drop-outs periodically.

[Kauffy]

I've noticed this happening only recently (the last week or so), but periodically, the ambient track of the audio disappears for a moment, and then resumes. Other sound-effects still occur, but this background noise disappears.

The sound I'm referring to, for example, is the kind of high white-noise whooshing sound of the outdoors when you're outside (not during a blizzard). This track disappears for about a second, and then pops back in again. It's as if there's a gap between iterations of the same loop. The other sounds aren't affected by it-- I can still hear my footsteps, etc. It's very jarring because the ambient soundtrack is so integral to creating the illusion of a massive world outside of you.
