i need help to solve this issue????

First, please don't double post.

Second, you haven't given anyone enough information to be able to even begin to help.

Read this:

Then read this:
https://help.ubuntu.com/community/SoundTroubleshooting
I'm going to go out on a limb and assume you're using Ubuntu. Even if not, much of that info is applicable.
