Why can't i access /dev/dsp or /dev/snd on my XO

On a normal PC I can read data from the sound device by doing from the
command line,  -

cat /dev/snd | od -x

(Using od just for readability)

On my XO I tried

cat /dev/snd/pcmC0D0c | od -x

and the error that I get is -

cat: /dev/snd/pcmC0D0c: File descriptor in bad state

I can't figure out why this is happening. (I vaguely remember being able to
do this on an XO long back.)
