            Bug ID: 797052
           Summary: [alsasink] Changing the device property has no effect
    Classification: Platform
           Product: GStreamer
           Version: 1.x
                OS: Linux
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gst-plugins-base
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: ceppofrancy at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Trying to change the "device" property of an alsasink element, after the
pipeline is set to "READY", has no actual effect on the used ALSA device.

I've briefly looked at the gstaudiosink.c source, and as far as I can tell,
in the "gst_alsasink_set_property" function, the property value
(GstAlsaSink->device) is changed,
but the real ALSA device reference (GstAlsaSink->handle) is not.
