I did that and it worked, thanks very much.
I prefer Chrome but the Pavilion came loaded with Explorer and I had resisted the temptation to download another browser because when I've done this on my other computers, I get overloaded with toolbars, add-ons, more intrusions, crashes and on and on. Another tech gave me this solution for a different problem on a different brand, and Firefox made it even worse.
But I am glad to have my sound back, thanks very much
