Hi,
I've got AD1881A soundcard on Intel82801CA/CAM chipset and I'm using
snd-card-intel8x0 (at least it succesfully loads...).
this is the dmesg output after trying to play a mp3 file with mpg123:
PCI: Enabling device 00:1f.5 (0000 -> 0001)
PCI: Setting latency timer of device 00:1f.5 to 64
ALSA pcm_lib.c:180: Unexpected hw_pointer value (stream = 0, delta:
-732, max jitter = 8192): wrong interrupt acknowledge?
ALSA pcm_lib.c:180: Unexpected hw_pointer value (stream = 0, delta:
-730, max jitter = 8192): wrong interrupt acknowledge?
ALSA pcm_lib.c:180: Unexpected hw_pointer value (stream = 0, delta:

ALSA pcm_lib.c:180: Unexpected hw_pointer value (stream = 0, delta:
-992, max jitter = 8192): wrong interrupt acknowledge?
It seems I'm having IRQ problems...
here's a cat /proc/interrupts

I enabled APIC in kernel, could it give problems related to IRQ sharing?
all other devices on irq=9 are working correctly and I already tried to
disable everithing except acpi (it's built into the kernel itself)
here's the dmesg related lines:
Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!
[...]
Using local APIC timer interrupts.
calibrating APIC timer ...
..... CPU clock speed is 994.2689 MHz.
..... host bus clock speed is 132.5691 MHz.
cpu: 0, clocks: 1325691, slice: 662845
CPU0<T0:1325680,T1:662832,D:3,S:662845, C:1325691 >
Can I force the IRQ selection for alsa modules?
thanks in advance
