Thank you all for your help and all the information you have given. There is a lot to read!
I agree that webcams are a minefield. In my experiments, I have found that mine works with some programs but not with others. Different distros give different results. There seems to be no consistency. Pulse Audio seems to have made things worse! I can only get sound working if I uninstall PA. Cheers and thanks again.
