The above pipeline looks like it is supposed to work just fine, note
however that adder is not doing any synchronization at all. If you need
that take a look at the audiomixer element from gst-plugins-bad (new
since 1.3).

Could you file a bug about that pipeline not working?

They don't do anything platform specific, so should work everywhere.
