------- Comment #9 from Stefan Kost (gstreamer, gtkdoc dev)  2007-05-21 17:04 UTC -------
I thought that queues should help, so I've tried this:

that of course works:
gst-launch audiotestsrc wave=2 freq=200 ! tee name=t ! volume ! adder name=a !
alsasink

this hangs (this is what I reported initialy);
gst-launch audiotestsrc wave=2 freq=200 ! tee name=t ! volume ! adder name=a !
alsasink t. ! volume ! a.

this still hangs:
gst-launch audiotestsrc wave=2 freq=200 ! tee name=t ! queue ! volume ! adder
name=a ! alsasink t. ! queue ! volume ! a.

It already hangs during linking (thats why the queues won't help):
