Low buzzing noise in headphonesHi all, this is my first post here so bear with me as this was the closest topic area I could find to get some help on a problem I have noticed. When using headphones on my W3J, there is a slight buzzing noise that is really only noticable when music is off, but it does affect watching a movie as it is noticable there. I found that it actually gets worse when having a USB device plugged in such as a mouse, which leads me to believe that it is some sort of electrical interference that is occuring...similar to the noise interference that you might notice in a poorly set up car stereo system (if anyone is familiar with what i am talking about). Has anybody else noticed this at all while sitting in a quiet room with no music on? I am downloading the driver update mentioned above to see if that has any effect. Anybody have any ideas?
