Hello again Mrstenter, Sorry for the delay, been really busy.
I have tried the system restore, and everything else I could think of, but still no sound.
Then, I turned off the wi-fi for some reason I can't now remember, and lo and behold......sound!
So now I know that the sound doesn't work if I am using wi-fi. Which really doesn't make any sense to me. How about you?
I look forward to hearing from again but I may just drop the notebook off at our local repair shop in a few days if I have no luck.
Yvonne
