Sorry no one ever managed to have a look at this issue until now. Is it still
an issue with current (1.x) versions of GStreamer? If yes, what's the best way
to reproduce it?

Does this also fail:

gst-launch-1.0 audiotestsrc ! audio/x-raw,channels=2 ! alsasink
device=pcm.Filter_RoutingUpmix

? If yes, could you make a debug log like this:

 GST_DEBUG=*alsa*:6,*audio*:6 gst-launch-1.0 audiotestsrc !
audio/x-raw,channels=2 ! alsasink device=pcm.Filter_RoutingUpmix 2>dbg.log

and hit control-C shortly after the distortion starts.
