I'm trying to get UPNP streaming to work. Rygel runs fine, however, all I get is a mono stream, even if the input is stereo. Doing some debugging, I replicated Rygel's gstreamer pipeline with
gst-launch-1.0 pulsesrc device=upnp.monitor num-buffers=100 ! audioconvert ! lamemp3enc target=quality quality=6 ! filesink location=test.mp3
where the problem is also apparent:
mp3info -x test.mp3
...
Media Type: MPEG 1.0 Layer III
Audio: Variable kbps, 44 kHz (mono)
...
Where does this pipeline lose the second channel? How can I debug this?

You never ask for stereo:
gst-launch-1.0 pulsesrc device=upnp.monitor num-buffers=100 ! "audio/x-raw,channels=2" ! audioconvert ! lamemp3enc target=quality quality=6 ! filesink location=test.mp3

Add a -v to the launch-line to see all the caps negotiated on all pads of the pipeline. Look for "channels" and see where it goes from 2 to 1.
