My processor-Intel Celeron (D) CPU 420@1.6 GHz,

OS-Ubuntu 9.10 [safe graphic mode],

I have also installed ubuntu-restricted-extras,

  Any one can fix the problem?

Hi Chandrasekar R,
Try installing "linux-backports-modules-alsa-karmic-generic" (then reboot). A number of audio problems on laptops have been resolved by installing this package. Also please ensure there are no extra "alsa model quirks" in your /etc/modprobe.d/alsa-base.conf.

I forgot to mention that you may also need to un-mute some audio channels using alsamixer. See the following question for details on how to do that.
