Lightbulb acipi and ICH7 HD audio prob. SOLVED

I have been suffering with this Acpi=off, Acpi=noirq to get sound (and boot probs) for a while.
first i had to get my machine to boot with acpi. that done i needed sound.

Please note i'm in Suse so with other distros you'll have to 'translate' and hopefully you can find these options.

Now my answer.
with acpi on (no need for noirq or noapic) i went into yast-> hardware->sound and choose edit for the card. there were 3 config options, the second being fix DMA pointer(0=auto,1=none etc.) select this and in the options field below enter 0 (for auto) then save/finish out. Reboot.

that was it. sound and acpi.

This worked on my HP dv8235nr laptop. CentrinoDuo T2300 Intel 82801G(ICH7 family)HD audio controller

I should note, this is from my /var/log/warn from the time i did this

it was repeated several times in the log and upon returning to the Yast sound manager the option is empty again. and i left it that way. Whatever this does/ still works every boot.

Hope that was clear enough.
