I have a similar problem too the one mentioned, but a bit different:

src->decodebin->audioconvert->audioresample-\
src->decodebin->audioconvert->audioresample-*->adder->osssink
src->decodebin->audioconvert->audioresample-/

the "-*->" arrow symbolizes that there lines are all linked to the adder. The
problem is that i want to add more audiosources dynamicly, after the playing
has started.

Does this mean i should block the adder src-pad, or should i block all the
audioresample-sink-pads?

cheers,
