Hi, I'm new to computer audio and I just purchased a new Pioneer N50 network audio streamer audio with Dlink NAS. Now my problem is I can stream aiff, flac, mp3.... but can't playback the wav file, once selected wav file to play, the N50 will come out a message "file not supported". Now I'm figuring out will this my Dlink NAS problem or N50 problem, but I suspect that probably will be the dlink problem because I have no problem playback wav file via USB.
