- * act in passthrough-mode if no conversion is necessary).
- *
- * <refsect2>

- * |[
- * gst-launch -v audiotestsrc ! audioconvert ! volume volume=0.1 ! oss4sink
- * ]| will output a sine wave (continuous beep sound) to your sound card (with
- * a very low volume as precaution).
- * |[
- * gst-launch -v filesrc location=music.ogg ! decodebin ! audioconvert ! audioresample ! oss4sink
- * ]| will play an Ogg/Vorbis audio file and output it using the Open Sound System
- * version 4.
