Problem porting a gst plugin from 0.10 to 1.2.0: pipeline in GST_STATE_PLAYING state, but no audio.

I am providing more details. It looks like that after the pipeline is set
to "GST_STATE_PAUSED" state, "gst_base_src_loop" in gstbasesrc.c stopped
being called. And it doesn't come back after the pipeline is in "PLAYING"
state. "gst_base_src_loop" is initiated by gst_pad_start_task(), but I
don't see either gst_pad_pause_task() or gst_pad_stop_task() called. Under
what other circumstances will the task stop calling "gst_base_src_loop"?
Note that souphttpsrc's activitiy also stopped when "gst_base_src_loop"
stopped being called.
I am attaching some debugging messages below.
Regards,
Lei
