I get no sound, even though the driver seems to load and cat /dev/sndstat

Try setting hw.snd.default_unit=1 in sysctl.conf. Most likely the order of the devices has changed.

---------------------------------------------------------------------------
------------------------------------------- FreeBSD Audio Driver (newpcm:
 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Analog Devices AD1981HD PCM #0 Analog> at cad 0 nid 1 on hdac0
 kld snd_hda [MPSAFE] (1p:1v/1r:1v channels duplex default)
pcm1: <HDA Analog Devices AD1981HD PCM #1 Digital> at cad 0 nid 1 on hdac0
 kld snd_hda [MPSAFE] (1p:1v/0r:0v channels simplex)
---------------------------------------------------------------------------

This looks like the output from the working configuration. Note that the first device is the analog output, the second is a digital output. When you load snd_hda using loader.conf, the order is likely different on your machine and the digital output is listed first. hw.snd.default_unit=1 would then direct the sound to the proper (analog) output.

Richard,
I am sure that this is what I did to my machine to get snd_hda to work.
