           Summary: Resources are not being freed when using
                    alsasink/pulsesink
    Classification: Platform
           Product: GStreamer
           Version: 1.6.2
                OS: Linux
            Status: NEW
          Severity: major

Hi, using Gstreamer 1.8.3 and gst-python 1.6.2 in Ubuntu 16.04 I see that
launching a pipeline with audiotestsrc and alsasink or pulsesink doesn't free
resources correctly.

If I check the /proc/<PROC_ID>/fd of the python script, I notice that the
opened files list grows each time I restart the pipeline.

If I use the C bindings instead of Python it works correctly.

I tried to create the pipeline in three different ways, and all seemed to give
the same result.

Gist with all the scripts used for testing.

Tested in Python 2.7.12 so far. We will test it in Python 3 next week.
