# Basic info <!--- Add commit SHA used to reproduce --> - Float reference: - Encoder (float): de0a9fca93 - Fixed point: - Decoder (fixed): d68c8f8447 # Bug description There is an assertion in frame 420 when BASOP decoder is fed with a bitstream generated from selection test material MASA using float encoder at 32 kbps and DTX enabled. Stack trace:  # Ways to reproduce Box folder: ...\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\issues\issue-xxxx <!-- Commandline or script --> Use this command line with the BASOP decoder and the bitstream provided in Box. ```bash IVAS_dec EXT 48 test_0752.bs 0752_BASOP_Selection_MUSHRA-7ab_s15.wav_32k_48-48___EXT.wav ``` The inputs to float encoder are also in the Box and you can generate the bitstream with ```bash IVAS_cod -masa 2 BASOP_Selection_MUSHRA-7ab_s15.met -max_band swb -dtx 32000 48 BASOP_Selection_MUSHRA-7ab_s15.wav test_0752.bs ``` <!--- Below are labels that will be added but are not shown in description.
