This only occours when DMA is turned on and there is ide disc access. It seems to be independent of the DMA speed. Also there is the same problem in windows with the manufacturers drivers. Here are my PC specs: Motherboard: Gigabyte GA-7VRXP Chipset: VIA KT333 / VIA VT8233A Onboard sound: Creative CT5880, Sigmatel 9721T CODEC (using alsa ens1371) I have also tried out another sound card (but with the same driver) with the same problems. I have heard that a BIOS PCI Latency setting can help this problem but cannot see this option in my bios. Thanks, Adam
