No idea, due to lack of hardware. This probably not entirely the fault
of sound driver.

1) Try disabling acpi or apic, or both.
2) Try using driver from , and tell us the

The worst thing you can do is try installing FreeBSD 5.x i386 (yes,
HP nx6325 + SB450, listen up!) and get 5.x modules from

There _is_ a reason why I keep updating the modules even for 5.x.
Several nx6325 users (probably others too) reported that using 5.x +
