My sound card, is a SoundBlaster Live Value. Whenever sound support is compiled in the Kernel, performance takes a huge hit, X runs about the same as on a P2 300 or so. But If I boot to a kernel that is configured exactly the same, the system is very responsive. I first had this issue with 5.1-Release. I then CVSuped to -CURRENT, and still have the same issue. I also tried swapping the card into a diffrent PCI slot, but that didn't help. Any ideas? Thanks, Matthew
