o When using the slider to move to a different part of the song, the
  spectrum analyzer freezes.  I think this is a problem with  the
  get_output_time or get_written_time functions.  Please send me a patch
  if you can fix it.
o Pausing a song or stream will throw away the number of audio frames
  specified in the buffer configuration dialog.
o The output device you specify in the configuration isn't actually used
  or saved yet.
o Doesn't call alGetParamInfo(res, AL_INTERFACES, ...) to get a list of
  interfaces supported by the output device.
