Thanks for your time and all these suggestions. Still no luck though.
Seems like you might not be able to have two files ending in alsa-base in the /etc/modprobe.d/ folder. That was the reason for the orange speaker indicator. I had alsa-base and backup-alsa-base, for some reason it was grabbing the settings from the backup.
Anyway, with probe only, orange sound indicator, when doing aplay -l I get
**** List of PLAYBACK Hardware Devices **** card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0
Attached are the requested logs. I tried using the hda-verb command you supplied, the only difference is that upon restarting after setting the command, I noticed the speakers crack, but still no sound. Not really sure what I should be looking for here.

Ok, seems like I have no luck. Here were some general tests that I did and the dmesg results:

This isn't too bad, but...

This seems more serious.

And this is better. So, obviously the problem looks like the communication with the secondary codec.
Now something weird is that when I initially changed to just model=hp-dv5, the mute light on my laptop went from orange to white. But no sound played. Then after the above tests failed, I started to try different models again (such as auto, laptop) and now that light is orange. So I changed back to just model=hp-dv5, and the light is still orange.
Any other suggestions?
OK, first try to load the module with probe_only=1 option. Reboot once after setting this model to restore the original BIOS setup. Then run alsa-info.sh --no-upload, and attach the generated file. If you get errors, try to get /proc/asound/card0/codec#* files, at least.
Then set model=hp-dv5, reboot and get alsa-info output, too.
Also, make sure to use the very latest alsa-driver snapshot, ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz Check the changelogs in alsa-driver*/HEAD and alsa-driver*/alsa-kernel/HEAD files.
The problem could be the invalid BIOS pin setup. In that case, you can try to change the pin control manually via hda-verb program, such as,
hda-verb /dev/snd/hwC0D0 0x0d SET_PIN_WID 0x40
See Documentation/sound/alsa/HD-Audio.txt in the recent kernel (found in alsa-driver snapshot, too).
