I have purchased the NVIDIA Purevideo Decoder version and would like to use my Creative Labs Audigy2 sound card to decode DVD Dolby Digital/DTS audio to output to my computer speakers.  How do I perform this?


The NVIDIA Purevideo Decoder plug-in enables the industry's highest quality DVD and MPEG-2 playback with ruch surround sound audio for Microsoft Windows Media Player and Windows Media Center Edition.  NVIDIA provides three different versions of the NVIDIA Purevideo Decoder, the Platinum, Gold and Bronze editions.  These versions differ in the audio features provided by decoder.  The NVIDIA Purevideo Decoder Bronze version only provides Dolby Digital 2 channel audio decoding however it can also do SPDIF passthrough to an external receiver which can decode Dolby Digital 5.1 and DTS.  The Creative Labs Audigy 2 family of sound cards is capable of decoding Dolby Digital and DTS in hardware.  If your computer users a Creative Labs Audigy 2 sound card, you may use its audio decoding capabilities to output to 5.1 analog speakers connected directly to your Audigy 2 sound card.  To do this, first you will need to set your Purevideo Decoder audio properties to output via an SPDIF cable:

Second, you will need to enable Dolgy Digital Decode from your Creative Labs Audigy 2 sound card properties.  Go into your AudioHQ settings inside of the Creative Labs folder and open the Device Controls panel.  Click on the radio button labeled "Dolby Digital (AC-3) Decode" from the Decoder tab and then click on the Close button.
