However the "cat /dev/urandom > /dev/audio " version should as MrCode says, produce white noise. I presume your sound works OK for "normal" stuff, like playing music or YouTube etc. If it does, then you haven't got much to worry about on the audio front, believe me.

sudo cat file.wav > /dev/dsp The reason you continue to get "permission denied" is that your shell first tries to open the /dev/dsp device for output, before running the command (which is sudo).
