### Basic info - Commit SHA: 8e40fa166bea8fa2b3c42077a80f21a70c7ab97f - Platform: all ### Bug description JBM has a function that determines the number of transport channels that need to go through the time scale modification. In case of MASA with DTX and decoding to STEREO with the first frame beeing a sid frame, it tries to access the first CPE handle which is still NULL at this point. ### Ways to reproduce Run the following command line with this VoIP bitstream [masa_nws.192](/uploads/639953da11eab66a74c438074f9b9d30/masa_nws.192) ``` IVAS_dec -voip STEREO 48 masa_nws.192 masa_nws_dec.wav ``` <!--- Below are labels that will be added but are not shown in description.
