Deadlock when calling gst_pad_pause_task going from PLAYING to PAUSE state

I am writing my own plugin for a live audio/video source hardware, it has 1 ALWAYS video pad and 1 SOMETIMES audio pad.
In my test application I connect to an xvimagesink and an alsasink.
When i close the window i exit the main loop and set the pipeline state to NULL.
In my plugin when going from PLAYING to PAUSE i call gst_pad_pause_task on each pad.
The gst_pad_pause_task call for the audio pad is locked in GST_PAD_STREAM_LOCK
The task for the audio pad is locked in gst_base_sink_wait_preroll call within the gst_pad_push call
Shouldnt gst_pad_pause_task be called when changing PLAYING to PAUSE ?
Should i push/send a special event on the pad before calling gst_pad_xxx_task function ?
Is there principle to follow to ensure no deadlocks when calling a gst_pad_xxx_task function ?
Thanks for your help,
