Playing vmsg files

Hi All I've finally got vboxgetty to receive the calls that come in, but now I'm stuck on how to play them. And also, the welcome message doesn't play either. I had the whole setup working under 7.1, but now I've upgraded to 8.0 I can't play the messages. susevboxplay gives an error "/usr/bin/aplay invalid option -- u" and thats it. On the old setup the files were *.msg files and could be played. In SuSE 8.0, they seem to be *.vmsg files. How to play these files? The audio system is working (at least for mp3 and ogg files). I've searched the SDB and Google but can find no mention of them. TIA jalal
