MP3 files are stereo, so you will only get stereo output.
but windows 7 play stereo on 5 .1 output using VLC & am using the same settings & drivers on windows 8 still doesnt work weird ?
Probably had a "Speaker fill" option enabled to copy the stereo output on the other channels from somewhere inside VLC. MP3's are stereo, so thats the only way you'd be getting output from rear speakers.
