Two days ago, I started having problems with my wife's PC not recording sound in Skype. Basically on wednesday it worked perfectly well, then the following day it didn't. Neither of us have made any changes/updates to the system. We are running Fedora Core 3 on that machine with kernel 2.6.11. Does anyone know how I could go about debugging this? Please note that I am not in Luxembourg, so I don't have direct access to the system. Mike
