Dell :: Check Your Headphones Jacks

I got a system exchange for my inspiron 1520 that had clicking/popping noises anytime audio was played, and my new m1530 has the exact same issue. (What I hear is a clicking/popping right before audio is played, and right after it stops for all my audio players. This also happens when it is paused.) I am wondering if this is just bad luck or if this is some mass hardware issue. So I pose the question, do you guys get clicking/popping on your 1520/1530's?

How to reproduce clicking/popping:

1) Plug in headphones

2)Turn volume down to less than 15% of the max volume (any higher and you risk ear damage)

3) Close media players, etc (not just pause, close them).

4) To try to standardize the tests, try running sounds directly from windows:
Right click the speaker icon in your tray, hit sounds. Select one of the sounds and try using the test button. The most noticeable clicking/popping are at the bottom under "windows speech recognition" as the pop at the end is about 1/2 second delayed on some of them. Device connect, device disconnect, and the logon/logoff sounds are also very noticeable.

What is odd for me is that each sound has different clicks/pops, and that they are consistent for each one. I also don't think its my headphones either, as I have three pairs (One Sennheiser, one creative, one sony) and they each produce the same clicking/popping pattern for each sound.
