MP3 will no longer play back (solved)

[wps]

I have audio recorded several mp3 on the PA5x. In the past they have played back fine. Now they will load into the style, show the length and play but no audio. Everything else play okay. I can play them on my computer from the thumb drive with no problem. What am I doing wrong? Tried restarting but it made no difference Thanks for the help.

Edit:
I figured this one out. Although the volume was turned all the way up on the sliders, somehow within the audio/video setting menu, the volume was set to 0. Have no idea how that happened.
