For licensing and copyright protection purposes, soundcard manufacturers are effectively prevented from adding DD/DTS decoders to their products. The reasoning is that the only legal use of DD/DTS decoders is for playback of licensed soundtracks from DVD movies. In your PC, a DVD player software must decode your DD/DTS soundtrack, NOT the soundcard.
Many customers have asked us how to use the S/PDIF Digital Input to decode surround sound from external players such as the Microsoft Xbox 360, standalone DVD players or other computers. Because of the above-mentioned licensing and copyright protections, this is not possible.
However, you can use a home theater receiver, or one of the new Home Theater. In a Box (HTIB) powered speaker systems from Logitech, Samsung and others.
Both of these product types have built in DD/DTS decoders, so will accept an incoming data stream from the Digital Out of Turtle Beach PCI soundcard and USB sound products.
NOTE: The Micro II driver does not contain Dolby Digital Live (DDL) capability. DDL is required for Dolby Digital 5.1 surround output from PC games. The Micro II optical output can send the Dolby Digital signal from DVD movie discs or other pre-encoded sources (pass-through).
MONTEGO DDL ONLY:
Our Montego DDL *encodes* game audio to the new Dolby Digital Live format, so you can hear positional audio from your PC games. It DOES NOT decode DD/DTS soundtracks. Again, you need a DD/DTS decoder, either a software version or a hardware decoder in your home theater receiver or Home Theater in a Box.
