When playing a song and using alsasink as output, I get the following 
assertion failure when trying to seek back to GST_FORMAT_TIME offset 0: 
 
GStreamer-CRITICAL **: file gstelement.c: line 922 
(gst_element_set_time_delay): assertion `time >= delay' failed 
 
and the seeking doesn't work. The seek event is dispatched like this: 
 
	ev = gst_event_new_seek (GST_FORMAT_TIME | GST_SEEK_METHOD_SET | 
GST_SEEK_FLAG_FLUSH,  
	                         (guint64) newtime); 
	 
	(void) gst_element_send_event (play->priv->audiosink, ev); 
 
Works fine for other audiosinks, and for any offset != 0. 
 
Stack trace (let me know if there's anything useful to look up): 
 

+ Trace 47222
