Two different soundcards, and three devices, seem to be detected:

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: Generic [HD-Audio Generic], device 0: ALC662 rev3 Analog [ALC662 rev3 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 2: ALC662 rev3 Alt Analog [ALC662 rev3 Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Device [USB Audio Device], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

If I could have sox (or any other software) send different channel outputs to
different soundcards, I could think of plugging a loud speaker into each
soundcard and so getting sound out to three separate places...

I normally use mplayer to play sound.

Thanks,
