Q:  Does this Soundcard decode Dolby Digital/ DTS Surround:

A:  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.

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 will need a DD/DTS decoder, either a software version or a hardware decoder in your home theater receiver or Home Theater in a Box.
