The FAQs have been reorganized. The new location of this question is FAQ#How can I tell ALSA to swap the left and right stereo channels on my soundcard?

This is supposed to work, although it doesn't for me. Add this to your /etc/asound.conf... 

pcm.swapped {
    type route
    slave.pcm "hw:0"
    ttable.0.1 1
    ttable.1.0 1
}

Then instruct your program to play to the ALSA PCM device named "swapped".

Maybe you need to have slave.channels 2 in there too?
