It seems to cover all 2GB, 4GB and 8GB models and none of the reports mention the sound coming from previous generation models. This has lead some to speculate that the noise is caused by a new component. Engadget decided to test it out with a 2GB model but could only hear a whining sound literally if the player was right beside their ears.
One owner, russgra, claims that the noise is the first thing he noticed when he got his 8GB Nano, whereas Energie said he would not have noticed if he didn't see the problem mentioned in the forums. This makes you wonder how many people have an actual "problem" with their model and how many are just unnecessarily whining.
