It sounds more to me like some common factor is inducing the clicks in both the intel8x0 and hdsp output. It would be helpful to test on a "known good" machine as many laptops are simply unsuitable for serious audio work (ACPI/SMM issues, etc). > my suggests: get the card working clickfree on native ALSA, then > native JACK (this means an app besides PD). you might need to try > ingo's kernel-branch, play around with buffersizes and samplerates, if > you are using "nvidia" or "fglrx" try "nv" or "radeon" All good advice > , renice your X server to 19, Not good advice - this should not help and may cause problems. > try booting with noacpi or noapic good advice > , and cat /proc/interrupts to see if sound is sharing an IRQ with > something else like video.. Video is not one to worry about - it is high bandwidth, but VERY little work should be done in the video IRQ handler. You want to avoid sharing interrupts with disk and network. But I don't think changing the interrupt will help at all. Lee
