I was just playing through things here and there. And eventually realize that tweeking alsamixer is solving the problem upto some extent. but we have to do it with every reboot.
command : "alsamixer -Dhw" or "alsamixer -c0"
try increasing all the playback volumes in it specially with the one with "front" tag.
This is giving quite a good volume in headphones.
