Lenovo Z560 Audio interference - Buzzing sound - How do I rectify the problem?

[balaram_poduri]

Yesterday I updated my Win 7 on Z560.  Also ran check disk using seagate - seatools, installed system mechanic and cleaned system, updated various software including java and deleted K-Lite.

I suddenly noticed that audio is not clear.   There is a buzzing noise while songs are played.  I notice song speed also varies slightly. 

I tried reinstalling VLC, Conexant HD Audio driver, Nvdia update.   Also ran check disk.  But the problem still persists.

Does any one know how do I rectify this?  What is the problem?

Balaram.
