If you use libsndfile it will let you read in the data in whatever format
you like. http://www.zip.com.au/~erikd/libsndfile/
sf_read_short() will give you 16bit data regardless of the .wav file
NB. most people dont use OSS anymore though, its not a very good API, JACK
and ALSA are much better, though may require kernel modules to be added if
your running an OSS only system.
