My computer has no sound out of the desktop speakers or the monitor speakers. I check the cables and sound settings but the sound only come out of the small speaker inside of the computer. Any idea?

Hi there and welcome to PCHF, have you got your sound drivers installed? If not right click My Computer and click Manage, then click on the hardware tab at the top and click Device Manager. now click on the + sign next to Sound Video and Game Controllers, and you should have something like AC97 Audio Device.

thanks for your responce ^^
i did what you said and hers what it says under the sound video and game controlers

audio codecs
creative sb live! series (wmd)
creative sblive! gameport
legacy audio drivers
legacy capture devises
media control devices
realtek ac,97 audio
video codecs

but the realtek ac'97 has a yellow circle with a ! in it

That means that the proper driver isn't installed..thus you don't get any sound through the soundcard...
Ehm..you can download the driver here: Realtek
good luck!
