That means when you recorded a video, an electrostatic crackling could be heard in the background when played back at loud volumes.
Sony Ericsson acknowledged the problem and said that the issue would be solved with the roll out of the 4.0.2.A.X.X firmware in October.
But unfortunately that didn't fix the issue, it just reduced the electrostatic crackling. The problem still exists but not in a way to detract the user experience according to SE
Since end of September the hardware is fixed and the electrostatic crackling is not there anymore.
