Sony Vaio VGC-JS2E no sound through speakers with Kernel 3.3.1

Hi guys.
I've unfortunately, since the upgrade to 3.3.1, started experiencing an old problem of mine with the speakers of my computer. Sounds plays fine and clear through the headphones, but there is no way to have playback through the main computer's speakers. I haven't touched any values in alsamixer, the configuration is the same as the working one with Kernel 3.2.13-1. I was experiencing the same problem with earlier 3.2.x kernels (see: https://bbs.archlinux.org/viewtopic.php?id=133952) but the problem had gone away for Kernel>3.2.5... unfortunately it's now back.

For the moment I'm running with 3.2.13, but since my google-fu seems to find a desert out there regarding this specific problem with snd-hda-intel, I am not sure it's a real bug and I want to be sure I'm not screwing up something myself here on my system before reporting it (and hopefully see it fixed).

Onto the information about my config and logs.

Card Info:

$:> cat /proc/asound/cards
0 [Intel          ]: HDA-Intel - HDA Intel
HDA Intel at 0xf9ff8000 irq 43

$:> lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller

$:> head -1 /proc/asound/card0/codec#0
Codec: Realtek ALC889

lsmod:

lsmod | grep snd

soundcore               5018  1 snd

/etc/modprobe.d/alsa-base.conf is as such:

# Working with 3.2 not with 3.3
options snd-hda-intel model=sony-vaio-tt

optionally, it works even as (the alias lines seem to make no difference):

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=sony-vaio-tt

ALSA stuff installed:

$:> pacman -Ss alsa | grep installed
extra/alsa-lib 1.0.25-1 [installed]
extra/alsa-plugins 1.0.25-1 [installed]
extra/alsa-utils 1.0.25-2 [installed]
extra/pulseaudio-alsa 2-1 [installed]

Logs from alsa-info.sh:

• Speakers & Headphones working OK (Kernel 3.2.13-1): http://pastie.org/private/wwiju4e4wevdjrlr0lg3q

• Headphones working OK, Speakers NOT WORKING (Kernel 3.3.1): http://pastie.org/private/hejlaudxdplgekga7zoa

I'll be happy to provide any other additional information needed. I really want to be 100% sure this is a bug in ALSA or the Kernel before submitting a bug report there, and not something I'm doing badly wrong. It's something that is really bugging me, so any help will be greatly appreciated
