Intel i7 HDMI Audio Support

[pete wright]

Has anyone been able to get audio working on an Intel i7 system using
DisplayPort or HDMI?  Specifically I have the following hardware
configuration:

FreeBSD boomer 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r297692: Fri Apr
8 03:07:13 UTC 2016
root at releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64

[pwright at boomer ~]$ cat /dev/sndstat
Installed devices:
pcm0: <Realtek (0x0233) (Analog 2.0+HP/2.0)> (play/rec)
pcm1: <Realtek (0x0233) (Analog)> (play/rec)
pcm2: <Intel (0x2809) (HDMI/DP 8ch)> (play) default


[pwright at boomer ~]$ sudo pciconf -vl
<snip>
hdac0 at pci0:0:31:3: class=0x040300 card=0x30d017aa chip=0xa1708086
rev=0x31 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Sunrise Point-H HD Audio'
    class      = multimedia
    subclass   = HDA

I have verified audio works in this configuration with Windows and
Fedora/Linux, but I am unable to get audio out of the intel audio
device.

Cheers,
-pete
