For the time being, I am able to listen to by using an earphone, but still problematic when using internal speaker..

Any idea?

what do you mean by "problematic? Do you get any sound at all through the internal speakers? Or does it come and go? Is this recent? What make is your laptop/pc, as it may be a hardware issue with Linux. Might be worth also looking to see if the BIOS has options for sound.

"Problematic" in my case means it works with earphone/headphone but it doesn't work with internal speaker. This happens after I reinstalled my ubuntu. Before ubuntu reinstallation, both ways (internal speaker+earphone) work out of the box..

Thanks anyway..Any idea?

Thanks a lot for the concern, everything[(internal+external) (mic+speaker)] is now working out of the box after upgrading to the latest linux kernel today :-)
