Doc , I'm not sure if your 100% there , on all the systems Ive had So far , its always been Green for Front left and Right, even on 2 channel Sound cards, on the Last 3 Surround sound cards its Been, Green Front Left and Right , Black Centre and Bass, Orange For Rear left and right, Pink for Mic, and Blue For line in
and i had 5.1 Sound Blaster
Then a 7.1 AC97
Then a 7.1 AC97 High Def.
Edit : i just noticed , on that Pic you posted , Black is for Surround Left & Right, that's not Regular Left and right. Green is normal Left Right, Even tho it says Front.
