Just for the record:

Today I found the time to fiddle with the various BIOS settings. It
turns out that if you set the field "Resources Controlled By" to
"Manual" in the "PnP/PCI Configurations" menu and then set IRQ 5 to
"Reserved" in the sub-menu "IRQ Resources" the sound output is okay
even if I use an ACPI enabled kernel.

auvia0 is now on IRQ 7 (used to be IRQ 9); if ACPI is disabled auvia0
is on IRQ 5.
