I have installed xp launch manager driver in my acer aspire 4520 laptop but it's not working

Hi sunshines803...

I think you have a corrupted audio driver..
You did not say what your operating system was so you will have to pick your driver from the list to work with your operating system...7, Vista, XP.
Note: Download the newest driver available for your operating system.
Go to the following webpage and download and install the audio driver for your Acer Aspire 4520.
