Audio will not work after a Windows 7 upgrade.



I have recently Installed Windows 7 to my Lenovo 3000 N100 Type- 0768, 6XG. Everything works perfectly accept for the sound. I have tried to install different audio drivers to see if anything works. I have also been on other forums to see if this is a common problem. It seems that some people get their sound working and others don't.


Does anyone know what sound driver I should be using? 

Could there be another problem which I don't see?

Is the best bet for me to restore my computer to factory settings!?



Please help me.

Re: Audio will not work after a Windows 7 upgrade.

I have had Win 7 working fine on two different N100s.


Sound can be a problem, if you do not know which

sound chip yours has. Only Vista drivers are available,

but they should work.


Here is the driver matrix, and the two sound drivers

are Soundmax and Realtek.


I am guessing Soundmax. But, just a guess.


Un-install any sound drivers you have installed (if possible)

and download the driver package.

When you "run" the downloaded *.exe package, it will extract

to a folder, usually C:\drivers\audio or similar.

You must then run the Setup program from that location.


Temporarily disable any antivirus program.

Right click it and choose "Run as Administrator".


If it still does not install, you can change the Compatibility

mode to Vista. Right click, choose Properties, Compatibility.


If still no joy, uninstall it if possible, and try the other.

Re: Audio will not work after a Windows 7 upgrade.

have you tried to install drivers manually?

after you locate the .inf file for the driver that you want to install, manually install the new driver. to do this, follow these steps:

- click start, right-click computer, and then click the tasks pane, click device manager.
- if you are prompted for an administrator password or confirmation, type your password or click continue.
- in device manager, locate the device for which you want to install the driver.

note to display hidden devices, click show hidden devices on the view menu.
- right-click the device, and then click update driver software.
- click browse my computer for driver software, click let me pick from a list of device drivers on my computer, and then click have disk.

- in the install from disk dialog box, click browse, locate an .inf file for the device driver that you want to install, and then click open.
- follow the steps in the update driver software devicename dialog box to update the driver
