Hello. i have a toshiba satellite p100 [model pspa3c-sd300e] i installed windows 7 and the audio does not work after the install. i cannot find the proper driver update for the sound device.

Yes,....good Ol' Windows updates. Known to knock a system partially out of commission.

Windows has lost the address to the Audio drivers. The reason it states Audio is working properly, is because Windows is full of it.

The Toshiba Satellite A25 series of Notebook PC's, did not come with Windows 7. It came with Windows XP. You, or someone else installed Windows 7.

The updates knocked the audio driver address file to the curb.
All you have to do, is install the Win7 installation disk again, and perform a Repair.
(Non-Destructive Installation)

OR, use the Restoration Disk, (Backup disk)

Toshiba eSupport does not provide audio drivers for Win Vista, or Win 7, for this model. Only Win XP,

{Do I think going to Device Manager, and rolling back the audio driver, or upgrading it, will help? NO }

Go to this website and select windows 7(32) or (64) depends on what version you are using then on the categories select sound and click Realtek Audio Driver for Windows 7 (32/64)(v6.0.1.5904; 09-03-2009; 60.61M) then click the red download now button to start downloading the driver. After downloading, install the driver that you have downloaded to update the sound driver of your laptop. If prompted for a restart, restart your computer then check your computer for a sound.

If the driver you downloaded will not fix the audio problem, you have to return to it's original operating system (windows vista) of your laptop by reformatting from a clean installation using windows vista installer.

Installation of Windows 7 is not supported by Toshiba for laptops made prior to 2007. Have a nice day.

Hi,

If you are asking if you can upgrade your laptop video card the answer is NO. Your laptop came with an INTEGRATED Intel Video card. Not possible to upgrade or install a different graphics card

You could try using the vista display driver from toshiba, or there is a driver for your Geforce go 7600 chip from nvidia here http://www.nvidia.co.uk/object/geforce_notebook_winvista_win7_179.48_beta_uk.html

do not know

Im sorry to tell you this mate but the driver needed is not supported by windows 7 its just one of those glitches that new OS's have give it time the driver will come out

http://www.softwarepatch.com/windows/uaa-bus-driver-patch.html download n install after that install ur audio driver,

Did you do the install by clicking on the setup file?
The other way of installing is to do from the Device Manager and click on Update drive and direct it to the location where the driver file is stored on your computer.
If that doesn't work, get it to search the driver off the Internet.

i see well then try this

did you go to toshiba and see if they were listed on their website?
If so let windows put in their own drivers.
uninstall them from device manager and scan for hardware changes.
