pinout for s/pdif_out2

Very few users will be able to identify a board DH57M01without the sticker with a made in china statement, DP/N 0G3HR7. That motherboard came out of a Studio XPS 8100.  No Pinouts whatsoever are made public for ANY Dell motherboard.

EVGA is not DELL and Dell does not publish ANY pinouts.

THIS IS NOT FACT ITS A GUESS YMMV. First task is to figure out with meter which pins are ground.  Then where 5v is.  Then its a 50 50 chance on IN VS OUT.

thanks for all responses...that's as far as i could find also ....  i'm pretty sure the second five pin configuration is correct .. is there something i'm missing to turn on the s/pdif_out2? ... doesn't seem to be anything in the bios... the audio settings in the nvidia control panel are setup  ... still no sound.. audio and video drivers are both the most current also

You have to go into audio and configure the output to be HDMI via SPDIF.  I would also DISABLE any onboard Audio other than the HDMI aka windows HD audio bus.
