Inspiron 1520 Headphone Jack Static/Buzzing

When using the headphones on my new Inspiron 1520, there is a buzzing/static noise.  It is consistent with all types of headphones and external speakers.  User groups I have found online confirm that this is a known problem inherent with this model.  It sounds like I'm listening to the morse code-like innerworkings of this machine as it performs tasks.  I primarily use this laptop at night for music and web-surfing and the use of headphones is important to me so that I don't disturb my sleeping family.  This static/buzzing noise is unacceptable. 

The motherboard has been replaced TWICE, the sound card has been replace TWICE and the hard drive has been replaced.  The sound is also there when the wireless card is removed.  After these repairs proved unsuccessful (and actually the first repair caused a hard drive error) I have since contacted customer service TWICE to let them know that the problem has not been resolved.  All I'm offered is for more parts to be replaced which will simply be a futher waste of my time as, according to all the information I have found, this is an issue that can not be fixed. 

Each time I call ends up taking about 40 minutes since I'm forced to start explaining my situation all over again to someone who apparently has no authority to do anything to fix my situation.  I am completely dissatisfied with Dell's inability to resolve my problem that I first reported on 1/17/08 along with the total lack of customer service I've received.  At this point, I believe I am simply being ignored since my calls are not being returned. I'm very disappointed with the poor service I've gotten out of the call center that I presume is in India.  I've had a couple of agents whose accents I can't understand.  I've had agents that put me on hold for several minutes only to come back and ask me the same questions I've already answered.  This has been a very frustrating experience.

This is the 2nd Dell computer I've purchased for my personal use, but I have purchased over 12 machines from Dell for my business.  I want this issue resolved with as little further disruption and time required on my part, as I've estimated that I've already spent more than 15 hours of my own time between making phone calls and reinstalling programs and tweaking settings after having this laptop hacked up twice.

My suggestion to customer service reps on the phone has been to replace this system with a comparable system that does not have the headphone issue.  As long as I have the same technical specs and XP Pro as the operating system, I don't care what model is substituted with this one with.  Seems simple enough to me, but apparently my problem is falling on deaf ears with the folks in Bangalore.  If Dell is unable to make this right, then they've have lost a faithful customer forever...one who has purchased at least 14 systems in the past.

I have sent this note directly to customer service, but I plan to broadcast the details of my experience to as many outlets as possible until the issue is resolved.
