Hadi,I'm very glad you solved it. It's a good restriction to be aware of and I'll note it in the user guide.
Good work on figuring it out.Unfortunately I use an Audio object from the DirectX.AudioVideoPlayback. library to play all the music and sounds. And so there's nothing I can do to make it play the 320 bitrate files if it does not already.
So I'm afraid you will just have to ensure any music files are in a bitrate that DirectX can handel.
Sorry about that. I'm excited to hear the music you create!All of you are bringing the game to a new level with your creativity and contributions.
