- * This element outputs audio to a
- * <ulink href="http://www.pulseaudio.org">PulseAudio sound server</ulink> via
- * the @pulsesink element. It transparently takes care of passing compressed
- * format as-is if the sink supports it, decoding if necessary, and changes
- * to supported formats at runtime.

- * <refsect2>
- * <title>Example pipelines</title>
- * |[
- * gst-launch -v filesrc location=sine.ogg ! oggdemux ! vorbisdec ! pulseaudiosink
- * ]| Decode and play an Ogg/Vorbis file.
- * |[
- * gst-launch -v filesrc location=test.mp3 ! mp3parse ! pulseaudiosink stream-properties="props,media.title=test"
- * ]| Play an MP3 file on a sink that supports decoding directly, plug in a
- * decoder if/when required.
