The recent patch hasn't fixed anything for me.
The source of my sound popping is from ambient sounds, specifically when there are wind sound effects from the weather, zone I'm in, or the "whoosh" sound from riding a mount.
Even in an empty area with ~144 FPS I encounter popping as long as ambient sounds are on. Tried changing sound sources, messing with equalizers, updating drivers, trying out the spatial audio feature, messing with listening position, etc. If ambient is off however, I get no issues whatsoever. Really frustrated and don't know what to do at this point. I've never experienced this prior to 6.0.
