System: NetBSD themobe 3.1 NetBSD 3.1 (THEMOBE) #9: Sat Jul 7 22:43:26 EDT 2007 root@themobe:/usr/src/sys/arch/i386/compile/THEMOBE i386

Unable to get audio to work either with native driver or with OSS Audio. I've had private communications from a NetBSD user using a very similar high definition audio controller from Intel with no problems. He suggested i test -current, which did not help.

If no one has time to handle this or pull a fix into 3.x and / or 4.x, if someone could point me at the right resources, i'd be willing to spend some time on it. I don't currently have time to find those resources and if someone knows, i'd appreciate the links.

from dmesg:

azalia0 at pci0 dev 27 function 0: Generic High Definition Audio Controller
