If you decode aac, then you might get hit by the change to planar format, which happened November 16, 2012 in the ffmpeg sources (although the effect is usually not a 'frying pan noise').

The change happened between ffmpeg-1.0.6 (which works fine) and ffmpeg-1.1.4 (which does not).
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?
