index_add is correct as originally written.
I suspect that pfb_clock_sync_ccf has a problem in it.
It looks like it only works if the number of output streams is 1 or 4,
but not 2 or 3. It needs to override check_topology to enforce this.
The two occurences of:
if(output_items.size() > 2) {
...
}
should probably be changed to: if (output_items.size() == 4)
It also looks like it's leaking d_diff_filters (should delete in the
destructor).
