A different "NO SOUND"

[jly!tica]

I have no audio. But contrary to the other posts, my computer does recognize the drivers and the devices. It acts like it is playing the videos, or CD or mp3, but no sound comes out of the speaker, or the headphones.
I've updated all drivers. Nothing is muted in volume control. All seems to be working just fine, except there is no audio coming out.........
Any and all suggestions are welcomed.

Maybe wrong connection of cables? What does your media player says when you lauch it? if nothing - that means everything is OK, but is either incorrectly connected, or sound disabled in BIOS (some motherboard allow it).
