[Voyage-linux] Distorted Sound

Hi,
Difference in lspci-v output is that my soundcard is using IRQ7 (instead of
20) when acpi=off.
But in Ubuntu(which works) it is IRQ20 again, so i postet output of cat
/proc/interrupt running ubuntu (2.6.35-25-generic)
Meanwhile i also testet tiny-core linux which has the same behaviour as
voyage - sound only works with
acpi = off.
strange, isnt it?
