Hi I have a small-form factor PC (KingYoung brand, model S645), which has 3 jacks connected to a Realtek ALC888 chipset. I have confirmed with the manufacturers the pin outs: 1) The front panel left side phone jack : Codec Line2-L & Line2-R (pin 14 & pin 15) 2) The front panel right side phone jack : Codec Mic2-L & Mic2-R (pin 16 & pin 17) 3) The back panel phone jack : Codec Front-L & Front-R (pin 35 & pin 36) I would like to update patch_realtek.c in alsa-drivers, to output 5.1 surround using these 3 jacks. Can someone give me some guidance on how I can do this? I have looked and studied patch_realtek as much as I can, I just need some help in getting started.
