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 speakersInternal mic - unknownthree 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:00:10.1 Audio device [0403]: nVidia Corporation MCP51 High Definition Audio [10de:026c] (rev a2)Subsystem: Wistron Corp.
