|You must install the right "drivers". |
The correct sound "drivers" are in the downloads for your model on the Dell web site, or on the Dell Drivers and Applications CD or similar that may have come with your model when it was new.
NOTE that sometimes the resident module(s) of anti-malware programs - a part that runs all the time scanning for suspicious activity - will interfere with the proper installation of third party software, the software will not install properly, and you may get no indication of that at all while installing the software.
To avoid that possibilty, you should always DISABLE the resident module(s) of anti-malware programs, BEFORE you install third party software (software other than most Microsoft Updates, etc., that did not come with Windows ), especially when it's a major or complicated software package.
E.g. if you are using the free or paid version of AVG, you should disable the Resident Shield in AVG's 's settings in Windows. In Norton (Symantec) products, there may be several things you need to disable, or set so they don't load for a specific short amount of time.
If you don't know how to do that, tell me which anti-malware software you are using.
When you are sure the software has installed correctly, re-enable the resident module(s).
People often install sound "drivers" incorrectly.
Sound and video "drivers" always have associated files that must be installed properly along with the actual drivers. If you install only the actual drivers, it's likely the device will NOT work properly.
Unless the instructions for installing a device tell you otherwise....
(this ALWAYS applies to video and sound adapters )
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.
The same applies no matter when Windows finds New Hardware !
If you DID install drivers that way,
(The following also applies if you want to un-install previous software, or re-install the same software)
- for video "drivers"....
- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting, let the desktop screen fully load.
Install the video software properly by running the proper download you got from the web, or if you have the CD that came with the video card that's in a slot, or if you have the CD that came with the brand name computer that has the Drivers on it, run the video software installation from the installation program on that.
for sound adapter drivers...
- go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting.
- go to Device Manager.
(e.g. RIGHT click on My Computer - Properties - Hardware - Device Manager)
If the sound adapter is still listed, RIGHT click on it and Un-install it.
If that was there, and you un-installed it, Reboot at least once.
DO NOT install drivers while booting.
Install the sound software properly by running the proper download you got from the web, or if you have the CD that came with the sound card, or if you have the CD that came with the brand name computer that has the Drivers on it, run the sound software installation from the installation program on that.
