Thanks, the command worked. But if I like to create a C application
that realizes this pipe I get this warning at start time:

(ogg_player:19889): GStreamer-WARNING **: Trying to connect elements
that don't share a common ancestor: alsasrc-source and wavenc-enc

Some code points:

  pipeline = gst_pipeline_new ("audio-player");
  source = gst_element_factory_make ("alsasrc", "alsasrc-source");
  enc = gst_element_factory_make ("wavenc", "wavenc-enc");
  sink = gst_element_factory_make ("filesink", "filesink-sink");
  ...
  gst_element_link (source, enc);
  gst_element_link (enc, sink);

So where is the problem?
