thanks for your fast answer.
it seems it does not work, it stalls or it gives errors in the flow.
the following is the code i am executing:

void add_sine(){
         GstElement *tsine;

         tsine = get_silence_bin();
         gst_element_set_state(pipeline, GST_STATE_PAUSED);

         gst_bin_add(GST_BIN(pipeline), tsine);


         gst_pad_link(gst_element_get_static_pad(tsine, "src"),
                 gst_element_get_request_pad(adder, "sink1"));

         gst_element_set_state(pipeline, GST_STATE_PLAYING);
}

this brings to a flow error. if i add a :
gst_element_set_state(tsine, GST_STATE_PAUSED);
before adding it to the pipeline, it simply stalls (i never get an  
async-done from the pipeline, that should be the message posted to the  
bus when the pipeline is in playing state again.
just for your information: this pipeline has a tee element outputting  
to two different sink elements (alsasink and shout2send);
any hint on how to get this working?
