Alright, I have a pair of headphones that I use at night so I don't wake everyone in the building up, and during the day I normally have a set of 2.1 logitech speakers. Right now they are connected with a in-line Y to split the audio. But I'd like to hook up a second pair of 2.1 speakers behind me so I can have 4 channel sound during the day. I'm wondering if there is any software out there to have 4 channel on the speakers, and 2 channel out to my headphones without having to rewire/configure it every day.
