Please provide a runnable, as simple as possible testcase for your
problem.

If the problem is that pads are not linked, check the code where you
expect them to be linked. Check if linking actually succeeds or if it
fails for some reason (which?).

If all is linked and the pipeline just does not preroll, check up to
which point in the pipeline data is flowing. Which sinks do not receive
data, where does it get stuck?
