From what I was able to decipher, 0x1e is a jack, external rear, with spdif out default output and optical connection. It is black. The same physical socket is used for the last 2 surround channels. Could you please clarify? Thanks in advance.
Take a look at Block Diagram of alc892 datasheet
http://www.realtek.com/products/productsView.aspx?Langid=1&PNid=24&P...
if you can confirmed the internal mic, mic jack ,line in , line out and internal speaker work as expected
the only pin complex which can be connected to rear [Audio Output] 0x0d is 0x15
seem that the pin complex for 4 jack 8-ch notebook are different from desktop with 6 jacks at rear panel
a 10 channel codec is able to provide volume control for internal speaker and 4 jacks
Thanks to Raymond's advice I was finally able to make the sound come out of the copper part of the spdif/side surround jack. I am pasting the diff created with hda-analyzer, please let me know if this gives you enough information to add proper 7.1 sound support for this laptop. Here is the alsa-info.sh with all jacks playing sound: http://www.alsa-project.org/db/?f=8f23e499727ec612ed925b81d3f38928e8f6aebb Of course, there is still no specific volume control for the side channel.

Upon further investigation I discovered that with the volume on the 0x17 can be controlled with center/lfe in alsamixer. I don't think it is the intended behaviour.
Is it with the very latest alsa-driver snapshot?
