# Basic info <!--- Add commit SHA used to reproduce --> - Fixed point: - Decoder (fixed): 496d928d46719161bc5c05600fc4de510d684e6e # Bug description There is a bit weird piece of code in initDiffuseResponses_fx(), see below ```c /* Diffuse only to horizontal plane IF enough loudspeakers */ IF( GT_16( num_horizontal_speakers, 2 ) ) { exp_var1 = 15; move16(); Word16 num_horizontal_speakers_isq = ISqrt16( num_horizontal_speakers, &exp_var1 ); // q15-exp_var1 num_horizontal_speakers_isq = shr( num_horizontal_speakers_isq, negate( exp_var1 ) ); // q15 assert( 0 ); /*No stream hitting*/ FOR( i = 0; i < num_channels; i++ ) { diffuse_response_function_fx[i] = mult( diffuse_response_function_fx[i], num_horizontal_speakers_isq ); // q15 move16(); } } ``` This is a pretty rare special case of custom loudspeaker output when transported signal is from horizontal loudspeaker layout and output has enough horizontal speakers present. Regardless, this is very easy to reproduce. # Ways to reproduce <!-- Commandline or script --> ```bash ./IVAS_cod -mc 5_1 32000 48 scripts/testv/stv51MC48c.wav debug.bit ./IVAS_dec scripts/ls_layouts/16ch_8+4+4.txt 48 debug.bit out.wav ``` <!--- Below are labels that will be added but are not shown in description.
