I am getting 5.1 sound on my Abit NF7-S in linux but in order for the sound to come out of the correct speakers, I have to swap the black and orange analogue sound leads over.
I need to swap back again when using 4 channel sound.
The colours of the speaker leads in windows where all works well do not correspond with the correct sockets (I have an Abit NF7-S).
Black lead ...... Orange Socket
Orange lead ... Black Socket
When working in linux this arrangement works fine until 5.1 sound is used.
But with linux nforce audio and 5.1 sound the plugs go in the correct colour sockets. Weird. And this leads me to the conclusion that the 5.1 part of the linux audio driver was written by a guy with an Abit NF7 who rigged up the sound leads colour for colour and proceeded to get the sound working "properly".
The socket colour mismatch is Abit's mistake as changing the windows audio driver for a generic realtek makes no difference to the mapping.
