1.	Solve : YouTube Problem?
Answer» No sound. How is that possible? Has the sound been switched off? I did not do that. But if switched off. How can I switch it on? I was on YouTube. I was watching a contribution. But I did not get a sound. The movie was playing, but I heard nothing. I have got a Dell laptop computer. The type is VOSTRO. I don't know a number. And starting TODAY it is very slow. All of a sudden. Is sound OTHERWISE working? Have you checked the sound button on youtube? It's the SPEAKER icon that is displayed on all youtube videos. Check your sound playing a something from your hard disk. If sound is OK, check the volume button in youtube below to playing video.
