Yes, I know. I shouldn't be using Lenny, and had in fact already tried to change to Squeeze, but had trouble with my mail, and reverted. But I am soon going to be installing on a new box, so am waiting until then. That's the excuses out of the way. ;-) Sound has disappeared. I imagine that it has got muted somewhere, but can't find where. My utter ignorance of audio systems doesn't help. Has anyone got any suggestions? Each and every one will be valued. Thanks, Lisi
