That sound like a problem with the player or plugin that is used to play the MP3 files.

Is the QuickTime plugin used to play MP3 files?


There are other things that need your attention.

Your plugins list shows that you have the Mozilla ActiveX plugin installed.

  • Mozilla ActiveX control and plugin module

The Mozilla ActiveX plugin is not compatible with Firefox 2 versions and later and you should remove it.

For instructions on how to remove the Mozilla ActiveX plugin see:

I removed the mozilla ActiveX. Which settings? Player Preferrences or Quicktime Preferrences would need to be changed?

Hi Cor-el, I had to reset my playback sample settings to 44.1 instead of 48k to get stuff to play correctly in Quicktime. They play right now. I appreciate your help!
