I made the mistake of thinking that the problem would get resolved with a firmware update, which unfortunately never came.
If you have the speaker "pop" issue take care of immediately, so you can take advantage of the Apple Care support.
Unfortanetly for me, my initial coverage lapsed, due to my hectic work schedule.
However, I just signed up for the extended Apple Care and will have a technician come out tomorrow to "fix" the issue.
They are bringing parts to replace the speaker, which I have a fealing won't solve the issue, according to the posts in the thread, but I'll at least be one step closer to a full replacement, which seems to be the only solution to this issue.
What a hassle...
