Hi, First, let's be sure that the sound card is on IRQ7 cat /proc/interrupts
If IRQ7 is the correct interrupt then typical reason that interrupts will get disabled is that the interrupt controller is receiving spurious interrupts on that channel. The interrupt happens, the interrupt service routine goes to read all the chips on that IRQ and finds that no chip says it generated the interrupt. Normally after a few of these the system will shut down the channel and interrupts for all devices on that channel are hosed. There are typically a few normal reasons for this stuff: 1) The system has some design problem. Internal noise messes with IRQ line on the motherboard. 2) A chip is bad or going bad. This could be the chipset of the sound card. Possible solutions: a) If the sound card is sharing and interrupt with other cards or devices then try to isolate the sound card on it's own interrupt. Try placing it in a different PCI slot. b) If this is an onboard sound ship then ensure that no other decide you have control over shares the interrupt. I.e. - if the sound card is sharing an interrupt with a PCI Ethernet adapter then try moving the NIC to another slot. c) If the above ideas don't work and this is a PCI device then try another sound card d) It is possible hat the problem is on the motherboard itself. The solution for that is not pretty. e) All of this can be caused by bad programming of the chipset. Investigate other kernels or distros for this sort of problem & potential solutions. Some distros add patches, some don't. Try a kernel.org kernel instead of a prepackaged kernel. Good luck. I've struggled through this a couple of times over the years. There are usually solutions but they are not (in my experience) always easy to find.
