I think I have fount the problem as to why my .wav voice mails that arrive by e-mail wont play.

On my n810 I installed MPlayer and was able to play them with out a problem, don't now how to use the command line version of Mplayer and KMPlayer doesn't play my Voicemail .wav files.

Excuse my ignorance but cant a codec be added or included with something like the "Extra Decoders Support" Application?
