You mostly tried the wrong model options.
According to the diagnostic script your Lenovo has a CX20549. I believe
that used to be known as a Conexant 5045 which means according to the
HD-Audio-Models.txt file the options to try are laptop-hpsense,
laptop-micsense, laptop-hpmicsense, benq, laptop-hp530.
This is from that referenced file:
Conexant 5045
=============
laptop-hpsense Laptop with HP sense (old model laptop)
laptop-micsense Laptop with Mic sense (old model fujitsu)
laptop-hpmicsense Laptop with HP and Mic senses
benq Benq R55E
laptop-hp530 HP 530 laptop
test for testing/debugging purpose, almost all controls
can be adjusted. Appearing only when compiled with
$CONFIG_SND_DEBUG=y
Your alsa sound driver version, at version 1.0.21 is old.

I'm running Ubuntu 10.04, and sound plays fine to the headphone jack
only - no sound from the internal speakers on this laptop.
I've tried following the normal diagnostic path, and tried
model=lenovo, model=laptop, and model=test but none help.
Here is the output from alsa-info:
