I'm not sure if the two issues are related at all. I have tried booting with iommu=soft, still no sound.[1] http://marc.info/?l=debian-user&m=122797497510015&w=2
I may be getting closer to the solution. I did get sound out of the machine a few minutes ago. I found this entry in /var/log/messages when the sound was working:
Jan 11 02:04:28 moe kernel: [ 6431.540366] ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16 Jan 11 02:06:39 moe kernel: [ 6578.403702] hda-intel: Invalid position buffer, using LPIB read method instead.
After a reboot and trying to use the sound, I see these messages in /var/log/messages:
Jan 11 02:16:20 moe kernel: [ 354.828388] ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16 Jan 11 02:16:20 moe kernel: [ 354.858407] ACPI: PCI interrupt for device 0000:00:14.2 disabled Jan 11 02:16:29 moe kernel: [ 364.409661] ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16 Jan 11 02:16:29 moe kernel: [ 364.437812] ACPI: PCI interrupt for device 0000:00:14.2 disabled Jan 11 02:17:12 moe kernel: [ 410.171457] ACPI: PCI Interrupt 0000:00:14.2[A] -> GSI 16 (level, low) -> IRQ 16 Jan 11 02:17:12 moe kernel: [ 410.203559] ACPI: PCI interrupt for device 0000:00:14.2 disabled
So it would seem that my sound is not getting (for some strange reason) an interrupt because it is disabled. Note, nothing was changed in the BIOS during this reboot.
Thanks for any clues, Mike -- Don't diddle code to make it faster; find a better algorithm. 02:25:01 up 14 min, 1 user, load average: 0.00, 0.04, 0.06 Linux Registered User #241685 http://counter.li.org
