WPF MediaElement: SpeedRatio not working for .m4a files?
原标题:

I m working with a simple mediaplayer based on this msdn example where the user can control volume, playback speed (SpeedRatio) and seek (Position) using 3 sliders.

Everything works correctly when I play .mp3 files, but as soon as I play an .m4a file the song playback speed, controlled by the MediaElement.SpeedRatio, is ignored. Volume and seek still works and the audio is working.

Questions:

  • Are there any logical explanations for this?
  • Any known solutions/workarounds to this problem? The speedratio is essential in my application.

Thanks, Avada
