Do you mean that you installed the deb of #7 in the kernel-rc3, there is no noise, while installed the deb of #7 in the kernel-rc4, still has noise? So looks like it is not the alsa hda driver's issue, since the deb contains the driver exact same as the rc3.
Please help collect two alsa-info.txt:
1) using rc4 kernel, plug headphone, when there is noise, please enable dump_coef and run alsa-info
$sudo
root@hwang4-Vostro-5390:/# echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef
root@hwang4-Vostro-5390:/# alsa-info
Then upload the /tmp/alsa-info.txt.xxx to launchpad.
2) using rc3 kernel, plug headphone, there is no noise, please also enable dump_coef and run alsa-info, then upload the new /tmp/alsa-info.txt.yyyy to launchpad.
Let us see if there is any difference in the two alsa-info.txt.
