Jacius Rubygame → 2.6

MP3 playback will default to mono and in some cases play at the wrong bitrate.

Test program:

require "rubygame"
song = Rubygame::Music.load("test.mp3")
song.play()
while(song.playing?)
end

When running this test program, SMPEG prints "Warning: incorrect audio format".

The problem seems to be in rubygame_music.c at lines 196-200 and in rg_music_load:

static int rg_music_play( RG_Music *music,

                       int fade_in, int repeats, double start_at )

{



  / Open audio if it's not already. Return -1 if it failed. /
  if( ensure_open_audio() != 0 )
  {

return -1;

  }



 ...
}

static int _rg_music_load( RG_Music *music, char *file )
{
  RG_WrapMusic *wrap = _rg_wrapmusic_alloc();
 
  int result = _rg_wrapmusic_load( wrap, file );
 
  _rg_music_associate( music, wrap );
 
  return result;
}

I think the audio device needs to be opened in rg_music_load() in order for SMPEG to set the correct properties for playing the song. Adding this line to rg_music_load() fixed the problem for me:

  if( ensure_open_audio() != 0 )
  {
    return -1;
  }
