how do you get the sound on for the vidoes.

Not all of them have sound so you may have just chosen one that didn't. Just watch closely if they don't have it.

I don't get sound on any of them. I used to back in Apr.

I don't mean to sound smart-alecky, because I've done this myself, but do you have the sound turned up properly on your computer? (I have often left mine muted and thought there was a problem with a website).

Also, is it just these videos, or do you have that problem with other websites as well?

I will check some other sites and see. thanks
