hi, i know this SC is software configurable, default is 5.1 speaker system, how do i change it from the default (5.1) to 2.1 in linux ? Edit: i know its a software configurable speaker output type, cos in XP, i had to configure the speaker system i was using, looked on net but can't find anything to configure the output type (7.1, 5.1, 2.1) Edit: when amp is turned on, it sound very bassy, like SC set to 5.1 speaker system, but instructions say to connect 2.1 speaker system and set to 2.1 speaker system, how in linux (kubuntu) ?
