Lost lap top volume

For some reason I have no sound from my lap top. I have a Dell XPS 140 and i have checked through the system manager and have not been able to fix the problem. I think I have lost a driver or something. I get no sound from speakers, head phones or CD driverolleyes

 

a mod will be along to move this to the proper forum (hardware)

lets check the obvious first, is mute on? or is the volume turned down all the way? is the volume turned on in the application you're trying to listen to?

yes?

 

yes to all

 

Second step: Is the Windows Audio service running?
Go to Control Panel>Administrative Tools>Services
Scroll down the list of services until you find Windows Audio
Open up Windows Audio by double clicking
Make sure it is running, if not, click on Start.
If the first 2 steps didn't fix the problem.
Third step: Check to see if your Sound Device drivers are OK. Use Device Manager:
To open Device Manager: Start>Control Panel> System. On the Hardware tab, click Device Manager, then click the plus sign in front of Sound, Video, Game Controllers.
In Device Manager, if there is a ? in front of your audio device, that means no audio driver is installed.
A ! means driver installation attempted but with problems.

 

I'm taking a short cut here, so do not download and install this driver, if you say "no" to any of the questions below.

Is your system actually a XPS M140? Is your OS Win XP? Is this your laptop?

If it is, then this is your audio driver.
Read this before trying to install your driver. How do I download and install a Dell audio or sound driver?
SIGMATEL - Driver

If not, we need some more info.
Fourth step: System Information

Thanks,
But I had already downloaded that driver. And I checked all the other things in the divice mananger u suggested.

 

All that is intact. There is a ? sign in front of other devices. When I try to fix it. I get a msg saying can not install, can not locate software. I don't have the disk it is asking for, if this is the problem

 

You might try by loading your chipset driver first, then your other drivers will be able to be loaded. There are two chipset drivers at this link. You didn't give any info about your system, so I don't know if you need one or both of them.
