For Xmas I had some Creative 5:1 speakers. Knowing that they would not work very well on my existing sound card I went and got a soundblaster PCI 512 card because it was cheap. I have downloaded the latest drivers but cant get the rear speakers to work, it says that I have to load the AUDIO HQ from the disk to switch the rear speakers on, thats ok and all the speakers work until I shut my pc down. Then next time I boot up there are all sort of driver problems and the speakers do not work. I am now using the up dated drivers. Under the change speaker settings in XP control panel the rear speakers do not work when the 5:1 speaker option is selected. The only way to get the rear speakers working is to select the Quadraphonic setting. Am I losing any sound quality my using this rather than the 5:1 option if the rear speakers were to work ?.
