I have AMD FX8350.
Just got on, turned everything up to test the audio. No crackle on zoning; no crackle in my house. Just did a couple 8 man roulettes and some FATEs in Thavnair and have not had any static yet. This is the first day of EW that I can actually enjoy the sound. Gonna probably do a new game+ or push an alt through EW MSQ just so I can hear it as it was supposed to be and actually play it without having a nervous breakdown. One thing I need to remember to do is back out and turn my system bitrate back up. I think I left it on CD quality after they suggested that weeks ago (gross).
