Did you set up a .asoundrc? Something like:

# ice1712 HW Device (NO FORMAT CONVERSION WILL TAKE PLACE)
pcm.ice1712 {
   type hw
   card 1
}
ctl.ice1712 {
   type hw
   card 1
}
# Automatic sample conversion etc...
pcm.d44 {
   type plug
   slave.pcm ice1712
   route_policy copy
}
ctl.d44 {
   type hw
   card 1
}

I can then do:

# ecasound -i:my.wav -o:alsa,ice1712

but the hw layer requires that we take care of formats matching (use
-f). With the plugin layer we can do:

# ecasound -i:my.wav -o:alsa,d44

and format conversion will be taken care of by alsa. The names I
choose were arbitrary...choose at will. BTW, the ice1712 in your config
appears to be card 1, not card 0. Hope this helps.
