The two cards are assigned to /dev/dsp and /dev/dsp1

When I change the "Audio output device"  parameter from ALSA:defaults to 
/dev/dsp1 I get no sound.
I use digital sound pass through mode.

So if ALSA:defaults is the output form the first sound card. what is the 
output form the second sound card.

In other words what is the equivalent for ALSA:defaults for /dev/dsp1
