Writing to /dev/dsp

Hi!

I am trying to decode a mp3 file using libmad's minimad in cygwin.
Does anyone know if it is possible to write the decoded file to dev/dsp
to get a real-time decoding? e.g.:

./minimad <test.mp3> /dev/dsp

I have tried the command above, but all I get from my speakers is
static. Do I have to set the sample size (16 bits), the number of
channels (2) etc.? If so, how can I do this?

Your answers will be appreciated,
Haavard
