Hi,
I noticed I did not have sound on my new thinkpad which has a newer
Intel 500 HDA chipset.

Looking at src/sys/dev/pci/azalia.c I noticed making the change in the
below diff corrects the issue with a new kernel build. It seems the
pci subsystem match inclusion may not be needed, but hopefully someone
smarter than I can figure that out (or help me figure that out).

I hope this helps some folks! I apologize that I am using 7.2-stable
and not -current.
Thanks,
