If I simply connect ladspa-sine-fcac to autoaudiosink and play the pipeline there is no sound (I checked that the oscillator properties are freq:440, amp:1.0). Do i need another element? Looks like oscillator doesn't push buffers or is not pulled or something. Jakob Leben |

Another detail: when tried it with gst-launch printing out messages: jakob@leptop:~$ gst-launch ladspa-sine-fcac ! autoaudiosink -v -m Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Got Message from element "autoaudiosink0" (state-changed): GstMessageState, old-state=(GstState)GST_STATE_NULL, new-state=(GstState)GST_STATE_READY, pending-state=(GstState)GST_STATE_VOID_PENDING; Got Message from element "ladspa-sine-fcac0" (state-changed): GstMessageState, old-state=(GstState)GST_STATE_NULL, new-state=(GstState)GST_STATE_READY, pending-state=(GstState)GST_STATE_VOID_PENDING; Got Message from element "pipeline0" (state-changed): GstMessageState, old-state=(GstState)GST_STATE_NULL, new-state=(GstState)GST_STATE_READY, pending-state=(GstState)GST_STATE_PAUSED; Got Message from element "ladspa-sine-fcac0" (state-changed): GstMessageState, old-state=(GstState)GST_STATE_READY, new-state=(GstState)GST_STATE_PAUSED, pending-state=(GstState)GST_STATE_VOID_PENDING; And after that it hangs.
