I have slightly different output:

cat /dev/sndstat

I set: hw.snd.default_unit=4 in /etc/sysctl.conf and rebooted the
system. Now sound works fine except that I cannot get "cdcontrol" to
output sound from the CDROM drive. No quite sure why that is. At least
sound does work in KDE4. Whether or not this is of any use to you, I
have no idea.

The fact that it "just works" in Windows 7 is not surprising.
