The Notebook Review forums were hosted by TechTarget, who shut down them down on January 31, 2022. This static read-only archive was pulled by NBR forum users between January 20 and January 31, 2022, in an effort to make sure that the valuable technical information that had been posted on the forums is preserved. For current discussions, many NBR forum users moved over to NotebookTalk.net after the shutdown.
Well all I can say is mine doesn't have this problem. Typically such noise can be heard if there is anything magnetic around it, perhaps something magnetic damaged the microphone/headphone jack?
Its not a common problem, and the majority of people don't get it... have you tried using a different pair of headphones other than the one dell provides? If the same thing happens, you might want to consider getting a replacement if it is too annoying.
Oddly i used to have this problem but after sending my 1520 to Dell for an unrelated repair I got it back and I haven't had the problem. FYI they changed my heatsink and fan. It is possible its a known issue and they are told to just kill two birds with one stone and fix the problem.
PS: I discovered it was fixed right after reading your post!
