Hello,

I am using a quick and dirty workaround for the same issue under -stable : I 
am loading the snd_hda from /etc/rc.local (i.e. late in the boot process) 
instead of via the loader (from /boot/loader.conf)

then, the snd_hda uses the "right" physical device (this is with a 780G-based 
integrated motherboard)

	Cheers
