Optical on the gigabyte

hey there is a SPDIF connector on the actual board , a black socket should that connect up to something? maybe that is where the cd rom connects to the motherbaord? cd roms need a special cable sometimes. maybe not that helpful.

i did give a fair few suggestions about the optical out ..skip back a few posts to one of mine. did you read it ? or am i being to obvious with the suggestions i gave????
