At first I thought the files were corrupted but when I transferred the files to my phone they sounded perfect. I assume it's a 'sound driver' or something, but I don't know alot about computers.



Any ideas whats going on or how I can fix It?

I would appreciate any info on how to fix this. Thanks.
