I dont know the name of my sound card is there is any method(any site) or any trick through which i get the name of my sound card without opening cpu

Try the manufacturer's website of your computer and the website of the sound card if you know it.

Get online and got to www.google.com In the google search box type: "Acer Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operating system when requested. Download and install the Audio drivers.

You can also try Driver Guide at:

Try the VLC Player. It comes with drivers and codec. I've seen it solve many sound and audio issues.

Try using VLC as your player. Go to www.google.com and in the search box type "download vlc" (without the quotes). Look for the Video Lan download from site www.videolan.org/vlc Download and install it. It downloads and installs in 3 minutes or so. It's a very fast player, smooth and it can play just about any type of dvd formats and media. It's totally FREE.

I'm not sure why you'd need to know the model number of your motherboard in order to get a USB to VGA converter working, but a utility like http://www.cpuid.com/softwares/cpu-z.html might give you the information that you need? If that doesn't do the trick, please post a little more information about the problem you are having, since someone on this site may be able to help diagnose and solve the problem.

open the CPU, look at the sound for the name and model of the card. go to their site and search for the driver. install it. alternatively, so to device manager under the system application in control panel, and see if the sound card driver is missing. refesh the device manager so that windows can detect it and see if windows have the driver preinstalled.

If you have onboard sound then open bios setup here u will definitely found the model no. & manufacturer of the motherboard. then noted it and download the drivers for this motherboard.

first your pc model second your sound card is integrated or separated one?
if integrated send to me your pc model and i send to you solution, second if it is separated open your pc case and witth a mirror without moving sound card from place try to look at dhe chip the letters and numbers writen there and send to me for a solution too.

Do u have built in soundcard or a bought one? If that is built in, just go to the site of maker of the mainboard, search with the model name of the mainboard, you should get the driver. If that is a bought one, Remove the cover of the CPU, look at the soundcard..look for the name of device part number. google with it..you should find the solution.

I m not able to download sound driver in my laptop

just go to the website of your manufacture.
mostly good companies provide
even if u dont get just go to realtek site and from there you can download the driver.
or atlast go in google search and just search for the driver by completely mentioning the model name,brand name or if ur computer is assembled the type the name of your motherboard.

there is usually a cd with drivers for the sound card. otherwise, you'll need to have the drivers downloaded from the manufacturer's website(which I don't know, without a name for your computer).

also, check your control panel settings.
