Hello,

I realize this isn't mythtv specific, however it is happening on my box which is used specifically for mythtv.

I have a weird issue where when I don't use the machine for awhile (say the whole weekend because I'm gone to the cottage) when I return, I have a Knotify message up on the screen telling me that the kernel has disabled IRQ #7 (Which I believe is the interrupt for the sound card). Then, when I try to watch any recordings or live tv, I get no sound.

A reboot always fixes the problem (until the following weekend when I go away again).

Anyone know why this is happening????

I remember doing battle with this issue when I switched my frontend to FC3 from gentoo. Now I have put everything into the master backend (PVR350, PVR500MCE) and it has appeared again, and obviously rebooting every time it happens is not an option for a general server/master backend.

The frontend was an Asus Pundit (SiS chipset) and the server is some generic Intel mainboard with a P4, so this may not work there, but I think I "solved" it last time by
 1) Disabling the printer port in BIOS, and
 2) Adding "parport=0 noapic nolapic acpi=off" to the kernel line in grub.conf.

Can't remember if that was what actually did the trick, will check when I get home tomorrow... =)
