I have been having this strange problem with PS3. Whenever i download 320KBPS New Hindi Songs and play it on the PS3 i get a hissing sound on the vocal. It sounds as if the file bitrate is low or the speakers are tearing. Anybody facing this similar problem. My PS3 is connected to Sony MUTEKI DDW-5000. If i play my older 128k mp3's it works fine.
