My husband got a laptop from his sister and she had changed some settings in it to make everything sound like chipmunks well we googled everything to try and fix the problem and nothing worked so in frustration my husband deleted the high deinition audio bus i know it sounds stupid to do that not sure what he was thinking. but now there is no audio at all and im not sure what i need to do to fix this issue when I went to the website to download the driver right from them i got an error after the download. the laptop is a lenovo 3000 c200 any advice would be great

Welcome to Techie7.

With the supplied info so far, the audio drivers would be here;
Lenovo Support - Download Drivers and Software (US)

I went there before I posted this and I downloaded every update and everything and nothing worked. The rescue and recovery is listed only for windows vista and i am running windows xp so when I tried that update it needless to say gave me and error. Not sure what to do next.

Also, when I go to my Device Manager there is a yellow question mark next to other devices when I open it up it says Audio Device on High Definition Audio Bus when I click on that it takes me to a section that has three tabs that say General Driver Details under the General tab it says Reinstall Driver when I click that it tells me "The hardware was not installed because the wizard cannot find the necessary software. ugh! so frustrated

Now that it's known you have XP, I see there isn't much there to choose from. Let's take this approach ;
Here is a link to Everest Home Edition (CLEAN FreeWare)

Alternate link;
|MG| EVEREST Free Edition 2.20 Download

Download, install, and run Everest Home Edition on this machine. (CLEAN FreeWare) Once it's finished loading and running, click the + sign next to;

Motherboard. Click on Chipset. Post the information listed (on the right) after South Bridge exactly as it is listed. (example; South Bridge: Intel 82801GB ICH7)

Multimedia. Post the information listed (on the right) under PCI / PnP Audio exactly as it is listed.

i clicked the link and hit run it says the it cant run it cuz the setup files are corupted and to obtain a new copy of the program. also i dunno if this is related but when i go to volume control it tells me there is no mixer device.
