I'm trying to get my soundcard(i82801CA(ICH3)) to work
correctly on my Sony Vaio PCG-GRV516G with NetBSD
1.6.2. The device is successfully registred at irq 9,
shared with device fxp0 and usb(mouse).

The interresting part: If i move my usb-mouse around
or my fxp0 is doing something(downloading), the sound
is playing. Verified with 'vmstat -i -w 1', the
counter for irq9 is incrementing.

With fxp0 and usb disabled, there is no interrupt at
irq9 if i'm moving something to /dev/audio!

I compiled a lot of differnent kernel
configurations(and different version(2.0)) and played
with:
options   PCIBIOS
options   PCIBIOSVERBOSE
options   PCIBIOS_ADDR_FIXUP
options   PCIBIOS_BUS_FIXUP
options   PCIBIOS_INTR_FIXUP
options   PCIBIOS_IRQS_HINT=0x0a00
options   PCIBIOS_INTR_FIXUP_FORCE
options   PCIBIOS_INTR_GUESS
options   PCIINTR_DEBUG
and also options AUDIO_DEBUG

Disabled all devices at irq9 except auich in the
kernel configuration and had same effect after
compiling and restarting(no interrupt).

I'm new to NetBSD: I think the ISR for audio should
point to the address where int auich_intr(void *v) is
located and not when i'm moving my usb mouse around.
Read a lot of Sony Vaio and buggy BIOS
implementations.

Any suggestions?
