I have some MP4 files that I'm transcribing, and yesterday when I downloaded them I listened to all of them briefly to be sure there was sound on them. Today there's no sound on ONE of them - but if I pull up that same file in windows media player it plays with sound.
I've also tried to convert this file to mp3, but there's still no sound.
Other files are fine, my computer plays sound elsewhere fine, just this one file that was fine yesterday and is not playing sound today.
Any ideas?
Thanks!
