Has anyone had success connecting a SB Live card to a Digital reciever ? I have run into a few problems, perhaps someone can offer suggestions
I have a SB Live! DE 5.1 card, (not Platinum or Value) as well as a nice Surround Amp which can do Dolby Prologic (surround info encoded into a sterio signal), Dolby Digital (up to 5.1 decoding) and DTS (a format newer than Dolby Dig)
At the moment I am running analogue cables (3 x sterio RCA) to the amp, but I would like to run a single cable (either Optical or Coax) and let my nice amp do the decoding.
Problem: When I send an AC3 stream to the amp (bypassing the sound cards 5.1 decoding) everything works great. But when I play games etc, only a Sterio signal is sent to the amp. (Orange connector on the Sound Card). I have noticed that the Front Left/Right is on the White connector, and the Rear Left/Right in on the Red connection.
Aaaaaarrgh ! Is there any way to mix these signals so that I have a single Digital signal sent to my amp? I guess this would probably have to be Dolby Digital 5.1 format. The Creative manuals are very vague on this subject.
My amp also has a fibre optic input. If I shelled out for the Optical Expansion Card (which costs almost as much as the Sb card itself ?!) would I be able to send the full 5.1 digital signal to my amp?
I have the SB Live original with the little daughter card. I also have the Cambridge Soundworks Desktop Theater DTT2500 with the reciever.
I connect the red Digital DIN cable directly from the daughter card to the reciever.
This is the only wire I have coming out of my soundcard. And all works fine. But the only time I get true DD 5.1 is when playing DVDs because games don't have 5.1.
True, Games etc don't encode the 5.1 dolby signal, but they sure DO use all 5.1 speakers (EAX effects etc). If I use the digital connection, then I am limiting my games to only 2 channels, while they actually can use all 5.1 channels.
If you want to get surround without using the daughter card you can get a RCA y-splitter(radioshack) and conect it to both front and rear outputs. This worx great on my Kenwood DolDig tuner. There is no discrete center channel but it does awesome 4.1 surround.
