Lubuntu Rythmbox Fix for AutoAudioSink and GStreamer

TLDR;
sudo apt-get install gstreamer1.0-alsa



FWIW, this is what happened to me installing Lubuntu 14.04 from a USB stick.

Did you install Rythmbox in Lubuntu and find that you can't use it because you get an error that says "Couldn't start playback" - "Failed to create autoaudiosink element; check your GStreamer installation" instead?

I did, and it was annoying. Couldn't find any real help anywhere no matter how much I searched. Eventually I stumbled across a bug report for it when I used the correct combination of magical keywords (not the autoaudiosink/gstreamer error). Hopefully you find this post faster now and it solves your problems.

The short version of the bug report is that Rythmbox isn't installed by default so they shouldn't support it by default and it acts differently than the audio players they do support, so ¯\_(ツ)_/¯ for now.

Rythmbox is trying to find an interface to output the audio. It knows that GStreamer has been installed and it tries to use it. Lubuntu's installation of GStreamer and fails trying to grab an autoaudiosink, whatever that is.

So you just need to give GStreamer a little something else to play with. Install the ALSA driver (make sure you restart Rythmbox) and go about your buisness.
sudo apt-get install gstreamer1.0-alsa
