Thanks that worked fine. This is how did it if someone else is interested. I removed all the error checking code and kept only the significant part. ... GstElement * outputsink = gst_element_factory_make( "gconfaudiosink", "audio-sink" ); GstElement * m_Playbin = gst_element_factory_make( "playbin2", "play" ); GstElement * level = gst_element_factory_make( "level", "gulevelctrl" ); g_object_set( level, "message", TRUE, NULL ); g_object_set( level, "interval", gint64( 250000000 ), NULL ); GstElement * replay = gst_element_factory_make( "rgvolume", "replaygain" ); g_object_set( replay, "album-mode", false, NULL ); gst_bin_add( GST_BIN( m_Playbin ), replay ); GstElement * sinkbin = gst_bin_new( "outsinkbin" ); GstElement * converter = gst_element_factory_make( "audioconvert", "aconvert" ); GstPad * pad; GstPad * ghostpad; gst_bin_add_many( GST_BIN( sinkbin ), converter, level, outputsink, NULL ); gst_element_link_many( converter, level, outputsink, NULL ); pad = gst_element_get_pad( converter, "sink" ); ghostpad = gst_ghost_pad_new( "sink", pad ); gst_element_add_pad( sinkbin, ghostpad ); gst_object_unref( pad ); g_object_set( G_OBJECT( m_Playbin ), "audio-sink", sinkbin, NULL ); g_object_set( G_OBJECT( m_Playbin ), "flags", 0x02|0x10, NULL ); ... This way it worked fine and get the level messages.

The elements need to be linked in the right order. What you need to do, is to create an own bin, add level, replay and the audiosink there, link them and set your bin as the audiosink. You need to add a ghostpad to the bin and set it to the first (yet unlinked) sink pad of you elements. Stefan <div class="im"> > The problem I have is that I dont get the Element messages.
