After reinstalling/installing an Operating System you can lose the Audio Drivers or sometimes they just corrupt.. Try reinstalling the Audio Drivers from the disk provide with your P.C./Laptop. If you no longer have the disk just visit the website of the makers of your P.C./Laptop or Motherboard and download the Audio Drivers from there, after that install them.
Thumbs up please if this works for you, thanks..
Just dont worry..
install this software and enter the key i gave to make it a full version and scan your system for finding and installing all the drivers you needed. It does automatically the driver installatio process.
some file which needed for the operating of that driver might have got corrupted or is not valid ...
once you try uninstalling and reinstalling the driver this will solve your problem ...
if you already did that & still persist the same problem then there may be some file missing in operating system . this might have happened due to some virus attack or while removal of some virus the file which is needed for the operation of that device might have got deleted accidentally ..
so just reinstall the operating system and then try installing the sound driver this will solve your problem ...
if you still persist the same problem then download the driver from net and install this solves your problem (there may be some problem in the driver which you are trying to install may be some file is missing)
so just following these steps your problem will be solved ...
thank you bye any doubts you can reply me i am always here to assist you rate my solution ....

hi, Actually downgrading from vistas to Xp is not supported these days in the new laptops. 1. If you dont have driver setup for XP. You can try to get the driver setup for other Lenovo models models with a Hit and Trial method. 2. Alternatively you try to find out the video card of the laptop..Nowadays laps are mostly with Nvidia. Nvidia gives driver for all Os. so try to download from the Nvidia Site. it also has a automatic video card detetection software. run it to get the exact drive. 3. For audio ..it might be a High definition audio ... so download the Universal audio architecture from the URL ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33867.exe or try google for UAA of lenovo. then try to download a sound driver like conexant high defintion audio driver. 4. while installing the sound driver it might show u that "media for the device not found" in that case open device manager and install the driver from device manager.
5. last option lenovo now offers a Downgrade to XP CD... for more details log onto .. http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=VSTA-DWNGRD#before
