The problem is that some of the demo code (like mono_tone.py) set the default
audio device to be hw:0,0 which only works for ALSA. Try setting the device to
/dev/dsp using
./mono_tone -d /dev/dsp
The code should not default to hw:0,0 since that only works on some machines.

The same thing applies to audio_copy.py -- it defaults to trying alsa.
