It is worth trying the model parameters (table below) for this codec to see if any of those enable your sound to work. It is worth trying any of these which sound feasable, starting with 6stack-dell as that sounds most similar to your machine:

        ALC883/888
          3stack-dig 3-jack with SPDIF I/O
          6stack-dig 6-jack digital with SPDIF I/O
          3stack-6ch 3-jack 6-channel
          3stack-6ch-dig 3-jack 6-channel with SPDIF I/O
          6stack-dig-demo 6-jack digital for Intel demo board
          acer Acer laptops (Travelmate 3012WTMi, Aspire 5600, etc)
          acer-aspire Acer Aspire 9810
          medion Medion Laptops
          medion-md2 Medion MD2
          targa-dig Targa/MSI
          targa-2ch-dig Targs/MSI with 2-channel
          laptop-eapd 3-jack with SPDIF I/O and EAPD (Clevo M540JE, M550JE)
          lenovo-101e Lenovo 101E
          lenovo-nb0763 Lenovo NB0763
          lenovo-ms7195-dig Lenovo MS7195
          lenovo-sky Lenovo Sky
          haier-w66 Haier W66
          3stack-hp HP machines with 3stack (Lucknow, Samba boards)
          6stack-dell Dell machines with 6stack (Inspiron 530)
          mitac Mitac 8252D
          clevo-m720 Clevo M720 laptop series
          fujitsu-pi2515 Fujitsu AMILO Pi2515
          3stack-6ch-intel Intel DG33* boards

For each you would edit the /etc/modprobe.d/alsa-base.conf adding a line for the snd_intel_hda at the bottom something like this:

    options snd_hda_intel model=6stack-dell

You then need to reload the module (rebooting may be simplest) and see if sound is detected correctly. If one of these model parameters does work for you then we can look at getting it detected automatically.
