every time i go to youtube the sound does not work but my speaker work cause when o go to my itunes and play a song and it works

what do i do to fix this

hmmm
i guess u have checked the volume button underneath the video when its playing????? sorry had to ask.

d.load and install the latest version of flashplayer.

errr you could also try Firefox 3 if ure on IE6 or 7
and vice versa.

also if u r using IE go to tools and manage add ons/enable/disable and check that flash player and other players are all enabled

the bar under the video shows how loud the sound is if thts not the problem get new speakers you could just have a malfunction!?!?!?

There is a sound button in the process bar under the video. Click on it and raise the volume up, that is most likely the problem.
