Hi Mister_x158,
Yes, you do need to reinstall your audio driver and here's how to get the driver and install it:
1. Go to
www.consumersupport.lenovo.comNote: If it's your first time, it will ask for your country or region. Please select the country/region where you are located.
2. You can either do Option 1: Enter a serial number. You can find your serial number at the bottom on a Lenovo sticker and it will say S/N which usually starts with EB followed by 8 digit number
3. Or Option 2: Select a product. For Brand, select Notebooks. For Family, select Ideapad S12. For Type, just select All types.
4. Click Search and you will have the list of drivers for your system. Scroll it down to Audio and select the proper one.
5. To know which one is the correct driver, look at the applicable OS. For example, your OS is windows xp then select the 5th driver on the list.
6. Click on the driver and it will bring you to the next page.
7. Look for the Download Here and click on the exe file
8. You will get a pop-up for License Agreement so click on I Agree
9. Then it will give another pop-up to either run or save the file.
10. Continue on installation, click Yes to all top overwrite existing file.
