Since the 1.0 packaging we automatically set the default pcm control to
use pulseaudio if pulseaudio is running, which makes alsa programs
automatically do the right thing for most people. I need to check if
there is a workaround to be able to handing parameters like the one
you're trying to pass.

A solution for you should be to use device=plughw:1 to play back on your
second device.

In any case lowering the severity to important, critical is far over the
top for this one :)
