I just put together a new PC and the motherboard came with onboard sound that is labeled different than I have ever seen before. The wiring in my case is labeled ( Ground, Return L, Return R, Spkrout L, SpkrOut R, Mic In, Mic Bias)
The labeles on the new motherboard are (Port1L, Port1R, Port2R, Sense_Send, Port2L, Ground, Presence#, Sense1_Ret, Sense2_Ret)
Which connectors go where?
Before anyone flames me... I know Ground goes to Ground.
