The FD BWE memory updates in the function `wb_pre_proc_ivas_fx()` are missing due to a bug in the following condition: ``` IF( ( NE_16( st_fx->extl, WB_BWE ) || ( EQ_16( st_fx->extl, WB_BWE ) && EQ_32( st_fx->total_brate, 0 ) ) ) && !ppp_mode ) { .... } ``` The bug is that `st_fx->total_brate `is in reality never equal to 0. Comparing the BASOP code to FLP, the `st->extl_brate` should be used instead of it. <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them.
