OK I got some life from GStreamer and my RPIv2 Install amixer modprobe snd_bcm2835 (or presumably use an image with audio built-in) amixer cset numid=3 1 (to set output to audio jack) gst-launch-1.0 audiotestsrc ! alsasink I get a tone out of the audio jack. So some kind of audio routing defaults issue. Alex
