I also tried to call gst_pad_perform_negotiate() for some links, but it always
returns false. it seems that negotiation can not be forced to made, it will
always happen at the first call to gst_bin_iterate().

my idea was to force link negotiation before the chains are build up totally, so
that there are not that long chains to traverse during the negotiation.

as the adder element expects all sources to be of the same audio format, I
expected to force the same format on all elements plugged in to the adder,
one-by-one. this way, all negotiation is done on shorter chains, and then
everything is just added together at the end.
