Thanks all for the help. Sound has started working on my laptop now. 
Thanks for the post Mark. For the benefit of all who are following this 
mail thread pasting the same solution here as well :

I found a solution here: http://ubuntuforums.org/showthread.php?t=452992 
<http://ubuntuforums.org/showthread.php?t=452992>
as toshiba satellite a135-s2386 have the same sound hardware this will work

here the solution if for some reason the site is down:

go to the terminal and:
sudo gedit /etc/modprobe.d/alsa-base.conf

then put this at the bottom:

options snd-hda-intel probe_mask=8 model=3stack

after that kill pulseaudio with this:

killall pulseaudio

after that restart pulse audio:

sudo alsa force-reload

and finally do aplay -l should have something like this:

adamtheo at laptop-satellite:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 6: Si3054 Modem [Si3054 Modem]
Subdevices: 1/1
Subdevice #0: subdevice #0

i guess this may help a lot of people here

Thanks
