Hi. I don't know how your audio got lost, but here are a couple of things you can try to do to get it working again.
Try this first.
Click your start button, then run this program:
type in: services.msc
This will bring up the services subsystem box
go to the bottom of the list, and it will say windows audio
click it one time.
If the service is not running, then there will be an option to "start"
If the service IS running, then it will have 2 choices :stop" and :restart service"
If it only says start, then click it, and it will attempt to start the service. If it works, then your audio should be restored.
If it says stop, and restart, then first stop the service.
Let it shut down the service, then try to start it up again. If it works, then this should get your sound going again.
If it starts your service, but you still have no sound, then you will have to run device manager.
To open it, open control panel, then system, then click on the hardware tab, and then click device manager.
Device Manager console will open.
This will show all the components of your computer.Look to see if there are any triangles with exclamation points. If so, and if it audio relayed, then uninstall those items one at a time, then right click in the open area of the info box, and select refresh.
You may have several items that need this done, or you may not have any at all that show the exclamation mark.
Next, you will want to click on sound, video, and game controllers.
There should be one that says something like ac'97 audio controller.
This is the one that you keep trying to install, but with no success.
double click it, an the controller properties box should open.
Click the driver tab, then click update driver.
click, no where it asks if it an connect to windows update, then click next
Click install automatically.
Wiindows will install the most compatible driver for your audio subsystem
then reboot your computer. This should fix your audio problems.
If not, then you have an onboard audio chipset failure caused bu a fault in the ac'97 controller portion of your system chipset.
Sometimes, this is a bios problem, where a glitch can disable onboard audio from within bios, so you will also need to check your bios settings,under system devices, or whatever it is called in your bios program.
Make sure onboard audio is enabled, if that option is there.
When I say this, I'm not talking about the built in pc speaker, that uses direct audio stream from the processor, so it wouldn't give you what you want.
I hope this has helped you some on fixing your audio problem.
