WARN message convert_taps_gint16_c: can't find exact taps and pipeline freeze

[Jack]

Hello,

I have a playing PIPELINE build with Python :

audiotestsrc wave=sine is-live=true ! audioconvert ! audioresample !
queue ! audiomixer ! tee ! queue ! audioconvert ! audioresample ! pulsesink

And I can listen the sound produced by "audiotestsrc" with is-live=true.
So the PIPELINE is working properly.

But, when I connect a Bin to the "tee" element, I get a lot of warning
with the message "convert_taps_gint16_c: can't find exact taps" and the
pipeline freeze.

The Bin connected to the "tee" element is (I don't put the properties of
"shout2send" here but the configuration is OK) :

queue ! volume ! audiopanorama ! audioconvert ! audioresample ! shout2send

Then I use this code to connect the "tee" source pad to the Bin sink
ghostpad :

self.ch_pad = PIPELINE.tee.get_request_pad('src_%u')
self.ch_pad.link(self.get_static_pad("sink"))
self.set_state(Gst.State.PLAYING)

My configuration :
Ubuntu 18.04
GStreamer 1.17.0 (GIT)
Python 3.7


Maybe gstreamer gurus can help me quickly to solve this problem ?
Best!
