           Summary: [pulsesink] should not block in open() if audio device
                    is in use
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: t.i.m at zen.co.uk
         QAContact: gstreamer-bugs at lists.sourceforge.net
      GNOME target: ---
     GNOME version: ---


When e.g. the flash plugin is hogging the audio device, trying to play a movie
in totem or with gst-launch-0.10 playbin2 will just preroll and hang before
starting to play, because pulseaudio seems to be blocking in the open() call or
whatever, waiting for the plugin to release the device.

Instead, pulsesink should post the appropriate RESOURCE BUSY error and get on
with things (so that autoaudiosink can skip to the next audiosink and try that,
like alsasink in this case).

Totem just hanging at the first frame without any explanation at all is not
very nice.
