HP Pavilion DV3 (dv3510nr) and HDA Intel : IDT 92HD7187X audio issue

Hello everyone
I really want to became a Ubuntu user, but unfortunately I'm having problems to get my audio working. Basically I'm trying the all troubleshootings possible to get it done, but I already had to reinstall the Ubuntu three times because the damages I already had trying things.
Now I'm running 9.10 version with ALSA v1.0.21 in my HP Pavilion DV3 series (dv3510nr).
I could find many others user of HDA Intel : IDT 92HD7187X with similar problems around the forums. The ones I tried, that I can remember, were:
https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/14434
https://answers.launchpad.net/ubuntu/+question/71735
http://bbs.archlinux.org/viewtopic.php?pid=502741

And others.
I checked the mute to be sure I wasn't doing anything stupid. Actually the microphone meter shows me that it is working. But the audio is ZERO.
I tried to add in the “etc/modprobe.d/alsa-base.conf” the lines below, changing the model to many different, but nothing came up.
Lines added:
# Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=3stack-dig
options snd-hda-intel enable_msi=1
options snd-hda-intel single_cmd=1

I checked user and root groups as pulse, pulse-access, audio, and video, but I couldn't find the pulse-rt, which maybe is missing at 9.10.

I ran the alsa.info.sh, which gave the follow result

I don't know what else I can do. This is the only limitation that is holding me out the Linux world. Without audio there is no way to have Ubuntu as my primary OS.

I would be more than thankful in having some help. I'm not the limited guy ever, but I'm not the best hacker ever.
