Hello Everyone,

I have above component in my laptop and lack the expertise to add it to to 
patch_realtek.c myself. 

I think I have collected all the relevant information if one of the developers 
wants to give it a try.

My Notebook: Medion 98300 (a.k.a. WAM2030)
(Please note: Medion is not an OEM. The board is nVidia based, OEM thought to 
be Wistron. Apparently rarely used sound component?)

Internal speakers
Internal mic - unknown
three jacks: headphone, mic, SPDIF(dual use jack).
Jack Sensing under Windows.
5.1 surround (sounds like the setup should be supported by 3stack-6ch-dig)

lspci:

Currently the only thing working is output via the internal speakers. 

Thank you very much, B.
