I've got a Dell 4300 1.6 Pent 250 meg ram with an 80 gig. It came with a standard Sound Blaster card. I tried one of the new Creative Extigy USB cards last night and was real disappointed. I tweaked every setting you can and it still didn't sound any better than the stock card in the machine. Plus it added a bunch of ticks. I thought at first that the ticks were the fault of too many USB devices working so I shut them down. I tweaked the settings for DMA like the instructions said, NO HELP. Well it's going back to circuit city today for a refund. What should I look at to improve my sound?
