Interesting— while I’m still one of those people that would not exactly characterize this issue as “popping” (it’s more like the sound of something vibrating that is loose, and only on the left speaker) — I AM a person who, in the timeframe where I experienced the issue, may have used both Teams and Zoom.
However, it is suspect that the issue carried over into the Mac restart sound, which one would think would be not affected by software incompatibilities.
I would caution readers: I think there are multiple problems readers are reporting here.
