I have an asus tf300t, My wife has a nexus7. Both are supposedly able to play wma files. When my wife is out of her office her voice mail goes to an email attachment, which she is supposedly able to access via email. The message is attached to the email, but won't play. According to the manuals wma files are supported. Specifically stated in the manual for the TF300T, it lists WMA, WMA pro LBR, WMA LOSSLESS. So I am confused as to why they won't play and why there is so much on forums that state that wma is not supported, even though the manual says it is. Any thoughts?
