I upgraded to 14.04 and now gstreamer is not working. What I am trying to accomplish is to hear the audio input on my computer coming from a ham radio. This is the command that I am using: gst-launch pulserc ! pulseink. This is the error message that I am receiving:
ERROR: pipeline could not be constructed: no element "pulserc". I think that I may be missing some plugins. I have been trying to investigate and found this troubleshooting website.
In it, I found this information. First I downloaded gstreamer-properties with sudo apt-get install gnome-media. Then I typed gstreamer-properties and a configuration page came up. 
With these configurations I clicked on "test" and was able to hear what was coming from the radio through the computer. But I am still coming up with the same problem when typing gst-launch pulserc ! pulseink. I found another clue- pulseink also gets a "no element" error message. Thank you again everyone for all of your help, I appreciate it.
Maybe you have spelled incorrectly in your question? or maybe you're spelling incorrectly in your command. You are missing 2 s ie., should be pulse
