Hum... that could mean the headjack is at least detected and sound gets 
properly routed to the correct ouput but audio level is very low. Have 
you checked the general hardware volume control slider of the laptop? 
Or by using "alsamixer"?

Have you tried by enabling the "[x] mute" switch? Sometimes the options 
are reversed ("on" is "off" and viceversa).

Do not modify nothing under /sys/class/sound*, that's atomatically detected 
on every booting.

Then, according to the "HD-Audio-models" list mentioned above you should 
use either of "options snd-hda-intel model=vaio" or 
"options snd-hda-intel model=auto", try with both options and don't forget 
to restart the system on every change (or restarting alsa service 
"/etc/init.d/alsa-utils restart").

As a last restort, you may also be interested in updating your alsa version 
to a newer one but I'm not sure what would be the easiest way to achieve this
in a "debian-way", maybe someone can tell :-?
