Help! I can't believe Dell is telling me this but its been 2 months and this is their final answer: even though my Dimension 4600 shipped with integrated 5.1 audio, it is not true 5.1 and will need a dedicated 5.1 sound card to get true, discreet 5.1. The tech. who spent the most time on this case said that their media edition PC has software that takes advantage of the integrated 5.1 audio but the regular 4600 doesn't. It ships with Cyberlink PowerDVD, which says it does not detect a multi-speaker device, and the tech. says I need to purchase the upgraded PowerDVD to enjoy the surround sound. He even admitted it was a bit ridiculous. I really want it for games, but none of my games dedect it either (obviously I tested the ones that I know support 5.1 sound). One note: when I run the Dell Diagnostics from the CD-ROM that came with the PC (booting to the CD-ROM drive) and run the sound test, it does play 5.1 discreet tones, so I know that this PC technically does 5.1 sound, I just don't know why none of the software takes advantage of it. Anyone have any ideas that these tech. people might not be familiar with? Also, whats a good (cheap!) 5.1 sound card ? The Dell tech. guy was happy to connect me to sales so I could get one, but I basically told him to f*ck off.
