How to modify the pipeline in test-onvif.c to stream a wav file

I'm trying to modify  this example
to play audio on a capable IP camera. I managed to compile the example and
got it working with the rednoise. What's the right way to pass an
appropriate (or any) wav file to the backpipe in

I tried the following but didn't play any sound:

backpipe = gst_parse_launch("filesrc location=output.wav ! wavparse !
audioconvert ! audioresample ! mulawenc ! rtppcmupay ! appsink name=out",

Any ideas?
