Hi Simon,

Good to see you on this list :-).

To answer your questions, basically you just have the setup up /dev/dsp for sample 
rate, channels and bitwidth (ie 8 or 16). then you can pretty much write to it 
and everything should work.

There is a really simple example of playing a sound file using libsndfile at

The part you should be inertested in is the function open_dsp_device().

For more advanced /dev/dsp material have a look at the OSS programmers guide at:
