Playing multichannel audio files

Hi all sox users.

I have a multichannel audio file: suppose three channels.  What I want is to
listen to that file by listening to each of those channels through a different
loud speaker.  In order to do so, I imagine each channel being sent to a
different sound card.  Can sox perform that, and how?  In sox manual I couldn't
find an answer.

Thanks for any help.

Rodolfo
