It took me quite a while to figure enough of the .asoundrc format to do what I wanted - bundle 2 channels into 1 stereo channel for use with my receiver and my headphones. Therefore, I have put in on this page for you to use/get inspired from.
So feel free to use this config or any variants you might create and please forward then to me so I may learn from them.
