No Sound

Hi,my PC is not giving me any sound either its headphone,internal speaker ,external speakers but my drivers are good it says in device manager "device is working properly" I need help from you guys.

We're gonna need a little more information than that :)

What are your external speakers?
What is your soundcard?
Are your drivers up to date? (not just "good", but the newest version)

And of course check the obvious!
Are your speakers switched on and turned up?
Have you muted sound in Windows?

i have Audionic speakers and i downloaded the sound drivers from providers site.

Ok, a few of my questions left unanswered there.

i have hp xw4600 workstation i have downloaded the audio drivers of that model from hp site and installed it and says "device is working" so i think drivers are ok

@oxymoron02
speakers are powered on and plugged in the right position
sound is not muted

Down next to the clock you should have a little speaker symbol. Right click this and then click on Playback Devices. You might see a few different things on the window which pops up, but one should be called Speakers. Make sure that beneath this it gives both the name of your soundcard, and also that it says Default Device.

It says "High Definition Audio Device"

Right click on "Speakers" and then click on Set as Default Device.
