[Discuss-gnuradio] synchronization between blocks

Hi all gnuradioers,

I have a problem to adjust delay between two paths in my flowgraph, and thus I have a question. The flowgraph is attached. As can be seen, there are two paths from the input. I would call one signal path and the other would be RSSI path. In signal path, signal is first filtered, demodulated and finally in clk_sync_... block the symbols are sliced. The second path is used only for rssi value. At the moment I have problem to adjust delay in rssi path so that correct rssi value is sampled at the moment of sampling symbol values. The only block that introduces delay is filter and it has 331 taps. So when I set delay to 331, the signal are not aligned. Is delay between this two paths constant during execution or not?
