            Bug ID: 755228
           Summary: audiointerleave: Won't negotiate with alsasink
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: nicolas.dufresne at collabora.co.uk
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Audio interleave in the case the channel-positions property is unset, will
produce in caps channel-mask=0. This won't negotiate with alsasink (but works
with pulsesink).

gst-launch-1.0 -v \
  audiotestsrc ! i.sink_0 \
  audiotestsrc ! i.sink_1 \
  audiointerleave channel-positions-from-input=1 name=i ! alsasink

While with pulse it works:

gst-launch-1.0 -v \
  audiotestsrc ! i.sink_0 \
  audiotestsrc ! i.sink_1 \
  audiointerleave channel-positions-from-input=1 name=i ! pulsesink
