Using Your Sound Blaster Recon3D PCIe 21
Watching DVDs
Your DVDs are encoded with Dolby Digital audio technologies, which have to be decoded to enjoy
multichannel audio on your 5.1 speaker systems.
Decoding with a software DVD player
You can use a software DVD player to decode Dolby Digital encoded signals from your DVDs, and
output multichannel audio through your audio card to your speakers.
To do so, you need to install a software DVD player such as PowerDVD or WinDVD (latest version
recommended).
Decoding with an external decoder
You can pass Dolby Digital encoded signals from your DVDs through your audio card to an external
decoder (for example, an A/V receiver), and ouput multichannel audio to your 5.1 speaker systems.
Some digital speaker systems are also capable of decoding Dolby Digital encoded signals.
To learn more, consult the documentation of your external decoder or digital speaker system.
