This error stream contains two elements (CPE and CCE). Because the stream is an erroneous for CCE at the time of initialization number of channel is 1 and at the time of execution it is 2. So code is modified to populate memory based on MAXIMUM CHANNELS allowed for SBR Bug:112711350 Test: poc Change-Id: Ia4b75694ae29d025289d0f85123ce2b24f9c1022
