I was wondering, but first some background, I manufacture computers and laptops. Background finished.
I am running the above mentioned laptop, which we manufacture by the hundreds. In windows the drivers give you the option to configure the type of sound mode the sound card should be run in.
What I would like to know is how to configure my working sound card so that the mic jack is subwoofer/center out and the Line-in jack as the rear surround, and the audio out stays the same, This is so that I can run (brag brag Sorry :) ) my logitech Z5500 sound system. As my PC with SB Live exploded in a storm the outher day ( I was not home) and now I have no usable sound system.
I have had a look at the alsa doc but am not sure what category this falls under.
The archive for this list are searchable so don't blast me if its been asked before.
