Comment (by qyot27):

 Building with --disable-yasm = decoding works

 Commenting out scalarproduct_float = still silent
 Commenting out butterflies_float_interleave = still silent
 Commenting out both lines = still silent

 Forcing SSE2 by changing line 35 of libavcodec/x86/sbrdsp_init.c from
         if (mm_flags & AV_CPU_FLAG_SSE) {
 to
         if (mm_flags & AV_CPU_FLAG_SSE2) {

 makes decoding work, but I don't know if that's the 'ideal' solution here.
