I placed a print statement with:

const char *av_get_sample_fmt_name(enum AVSampleFormat sample_fmt);

and the return value for 1.0.6 is s16, while for 1.1.4 is fltp, which I 
assume is float planar.

Does this mean I need to use the swresample library to resample the 
sound to s16 which the audio card can play?
