I'm trying to put together an HTPC. It's a brand new Dell 8200, which came with a SB Live sound card. I'm guessing this card is 5.1 capable. (?) The PC is running WinXP Pro and I've installed the latest SB drivers from the MS website. I've connected the digital out of the card to one of my processor's digital coax inputs via a mono 3.5mm-to-RCA adapter. I've connected the digital and analog outputs of the DVD drive to the sound card. Using the Control Panel applet, I've set the speaker config to 5.1 and selected the "Digital Output Only" option. I've also tried various combinations of muting/unmuting the digital and analog inputs in the volume control applet. PowerDVD (XP 4.0 Deluxe) gives me only 3 choices for audio output: 2 channel, 4 channel, and SPDIF. I do NOT get the 6 channel option as indicated in the manual. (I do have the 6 channel DD/DTS version of PowerDVD, apparently.) Could PowerDVD be thinking the sound card is not capable of 6 channels? When I select the SPDIF output option in PowerDVD, I get NO sound. Zippo. Nada. I've tried every combination of settings I can think of, with no luck. The 2 and 4 channel settings work OK. Can anyone offer some advice on whether I've hooked up the hardware/software correctly? Is this lowest end SB Live from Dell not 5.1 capable? Thanks!
