  74 This element lets you adjust sound input and output levels with the
  75 Open Sound System (OSS) version 4. It supports the GstMixer interface, which
  76 can be used to obtain a list of available mixer tracks. Set the mixer
  77 element to READY state before using the GstMixer interface on it.
