Hi,

Some more ideas:

2 channel 16 bit will only work if you turn off bitperfect. The lowest 
number of channels the device exports is 4 for playback. That means the 
kernel will re-format 2 channels to 4 channels always and that is done 
by the PCM feeder. You'll need to check that there is a filter which 
handle that.

You might want to install virtual_oss from ports to handle this device 
properly.
