you would need an ~/.asoundrc file that defines a "route" "plugin
device" that explicitly has only 1 (or 2) channels that are mapped to
the relevant channels of the real card. i'm afraid i don't have the
time or memory to provide an example - google will help, for sure..
then tell aplay to use that device instead of "default:Card=DSP"
