This would be the info from avcodec.h for avcodec_decode_audio2

 * @note You might have to align the input buffer \p buf and output buffer \p
 * samples. The alignment requirements depend on the CPU: On some CPUs it isn't
 * necessary at all, on others it won't work at all if not aligned and on
others
 * it will work but it will have an impact on performance. In practice, the
 * bitstream should have 4 byte alignment at minimum and all sample data should
 * be 16 byte aligned unless the CPU doesn't need it (AltiVec and SSE do). If
 * the linesize is not a multiple of 16 then there's no sense in aligning the
 * start of the buffer to 16.
 *

Will cook up a patch for the pre-release.
