Sound Device Problem

It's a possible problem with the driver or the sound card may be disabled. To check if the sound card is disabled or drivers not installed,
1. Right click on "My Computer" select "Properties"


2. Click "Device Manager"

3. From the list, you should see a "Sound Controller" and if you click on the drop down arrow beside it, you should see the audio driver installed(ex. High Definition Audio Device... audio driver name may vary depending on the brand of the laptop).

4. Right click on the sample "High Definition Audio Device" then select Properties. If it says device is working properly then there shouldn't be any problem with your audio.

** If the Sound Controller is NOT installed properly you need to download the Audio drivers from the support site of your Dell computer, http://support.dell.com , be sure to select the correct model of your laptop and operating system of your computer. Once you have downloaded and installed the drivers, Audio should work fine not unless it is the hardware itself that is damaged.
**Also don't forget to check if there are other external audio output devices connected to your computer, please do test if working properly.
Hope this helps. Glad to be of service.

Check the device manager for any conflicts with the drivers. There would be "Other drivers" listed if there was any drivers that were not installed correctly. If there is any listed try right clicking on them and selecting to reinstall drivers.
To get to the device manager:
Right click on my computer or Computer > select properties > then click on hardware tab on top then device manager or click on device manager link.

sounds like you need drivers installed for your sound card(if your computer has one, which most do now) ... what kind of computer do you have? Make and model? What Operating System(version of Windows) are you using also? I'll gladly help you find drivers.

My friend, I am glad you have identified your sound card. Remember, when dealing with a computer, it doesn't care what you know about it, the computer must know about it - where ever it is.

Please check your device manager to see if the sound device loaded properly and the driver is running. You will probably have to reload these drivers - get them from the manugacturer of the computer/mother board.

What ever happened was 97% not caused by the power supply replacement.

Thanks for your question at FixYa.com

Need to know your laptop model?
Download drivers from dell or the manufacturer of the sound card/mainboard. As you install these the No device should vanish and it should start working. Also try windows update...custom install...optional updates .look for sound drivers like AC97 or realtek, if they are listed select them and try that.

Try going into device manager
click start
then control panel
then system
they hardware
then device manager
if there is a yellow !mark next to sound then use the properties tab to reinstall the the driver
Hope this helps

go into the control panel and into the sound manager,(start,control panel, sound and other audio devices) then check all the volumes are up and not muted.
If that fails, go into device manager, expand the device tree and right click on the audio device, click properties and check the driver is installed, and if necessary update the driver or roll back the driver.
