Hello all! On Skype, I could hear the other people but I couldn't be heard by them. I tried clicking on all sorts of things to do with sound in the control panel but nothing worked. On top of that, I now hear a background computer noise, pings and keyboard tapping. Does anyone know what I did and how I can get it back to normal? Help with the Skype problem would be appreciated too, but this background noise is so annoying when I'm trying to listen to the iPlayer radio. Thanks!
