I found a better solution to my problem with my HP N5430 laptop over on the alsa-devel list, my sound had quit working also. The new solution, which was pointed out to me by Henry Yuan was to boot with lapic. I had noticed in the dmesg output that a lapic existed but was turned off by the bios, and a pseudo local apic was being used, this caused problems with APCI and my sound. If you would still like the dmesg I would be glad to send it. Steve
