Audio popping issue

[XenophineEX]

Everything with snow has sound issues for me. I am up to the second expansion now. Almost everything required in Heavensward stuttered. I only just got to Stormblood. As far as aoe, as a dragoon I got my first aoe combo at 62. The other 2 have cd's 1 is 30 seconds, the other 3 minutes. I see at 90 I have as much aoe as other people, but should I run any dungeon lower than when I get that aoe, well there you go.
Soundwise everything that involves aoe immediately starts skipping, there hasn't been one major pull with over 6 mobs that it hasn't happened. Sounds like the sound effects got thrown into a fan. and it doesn't stop. The healers with the big aoe circles make it worse.

Keep in mind, processor never goes above's 40%; and fps never goes below 60 fps when the stuttering happens. Processor is also a cool 75 degree's while playing. That is in Fahrenheit.

Mayhap the game isn't using all the cores it could be? I can try changing its affinity.
