LOL, yeah you do... We've been over this a thousand times. Have a read back through the entire thread. Myself and a few other associates have it on very good accord from some executives at Apple that there are ZERO exceptions to this issue. To say that there are would indicate a HUGE batch of faulty hardware because Apple internally point blank states that this has NOT been fixed and that it seems to be some sort of HW/SW interaction. Maybe you aren't doing anything to replicate it. I suppose that is possible (not really), but I don't know how when even receiving email and text alerts causes a slight "clicking" sound just a tiny fraction of a second before the alert sound itself. It is difficult to hear, but it's there. Also, it makes a difference if you have your machine set to 44.1 or 48. Apple did make a slight attempt to patch 48 but "forgot" to work on 44.1. Set your machine to 44.1. Put your head close to the left speaker. Have someone send you a bunch of texts in succession and listen for the "click" just before or seemingly at the same time as the alert sound... Have a nice day.
P.S. I do have OCD and I am a total perfectionist. It's a blessing and a curse.
