wavelab pro 9.5

I recently install WAVELAB PRO 9.5. Everything run smoothly except the autoplay mode at the FILEBROWSER tag. I cannot prelisten any of the known audio file types. I use the RME UFX audio card. The problem is that the specific function works perfectly on WAVELAB PRO 9.1 which is also installed on the same PC.
Any thoughts ?

Known bug for encoded files. Will be fixed in next patch.

thanks
