I can't manage to get an audio interpipe connected

[mlopez-egi]

I can't manage to get an audio interpipe connected.
(gst-interpipe version: 1.1.8)
Using:
gst-launch-1.0 audiotestsrc freq=1000 ! audioconvert ! audio/x-raw,channels=2 ! interpipesink name=loopmonitor

gst-launch-1.0 interpipesrc listen-to="loopmonitor" ! alsasink

I get:

Please, can you help me?

They need to be run in the same process in order to communicate, so you'd need a pipeline like: audiotestsrc freq=1000 ! audioconvert ! audio/x-raw,channels=2 ! interpipesink name=loopmonitor interpipesrc listen-to=loopmonitor ! alsasink for it to work.

If you need to move data between different processes, then you'll need to look at other elements, such as gdppay/gdpdepay and shmsrc /shmsink. If you just want to have different pipelines, RidgeRun's gstd works well for that.
