Hi Shree.
I will provide you a driver which has worked for lots of people. Try this driver and let me know.
This model of Presario has an audio controller that supports the high definition audio. You need to have Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio installed on the computer before installing the audio driver.    Here is the link for the Microsoft Universal Audio Architecture driver that need to be installed before installing the audio driver:    ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33867.exe  
  After installing the UAA driver reboot the notebook and install the audio driver from the following link:

Conexant CX20549-12 High Definition Audio driver:    ftp://ftp.hp.com/pub/softpaq/sp35501-36000/sp35940.exe
