aplay -D plughw:1,0 file.wav
this will actually put the output across all outputs, but it should
accomplish most of what you want. to get just the first two channels,
you will need to investigate the mysteries of the .asoundrc file and the
"route" ALSA "plugin".
ALSA "hw" devices are restricted to only formats that the underlying h/w
supports; in this case, 26 channels of mono, non-interleaved, 24 bits
packed into 32 bit samples.
