[Bug 237340] Unable to make HDMI sound works with HD630

            Bug ID: 237340
           Summary: Unable to make HDMI sound works with HD630
           Product: Base System
           Version: 12.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: misc
          Assignee: [hidden email]
          Reporter: [hidden email]

I can't make the sound pass thru HDMI port. The involved hardware is:
motherboard Asus H170I-PRO with embedded sound card Realtek ALC887 + processor
i3 7100T (Kabylake). The graphic card used is the HD630 from the i3.

Two hdaa devices are detected (ALC887: hdaa0 and Intel Kabylake audio: hdaa1).
At the base, there isn't any listed HDMI device:

------------------
$ cat /dev/sndstat
Installed devices:
pcm0: <Realtek ALC887 (Rear Analog)> (play/rec) default
pcm1: <Realtek ALC887 (Front Analog)> (play/rec)
pcm2: <Realtek ALC887 (Internal Digital)> (play)
pcm3: <Realtek ALC887 (Rear Digital)> (play)
------------------

I tried to select each of the pcm devices (hw.snd.default_unit=...) but I got
no sound from HDMI.

It's possible to make an HDMI device appear by adding
hint.hdaa.1.nid3.config="conn=jack" (or "conn=Fixed") in /boot/device.hints:

------------------
$ cat /dev/sndstat
FreeBSD Audio Driver (64bit 2009061500/amd64)
Installed devices:
pcm0: <Realtek ALC887 (Rear Analog)> on hdaa0 (1p:1v/1r:1v)
pcm1: <Realtek ALC887 (Front Analog)> on hdaa0 (1p:1v/1r:1v)
pcm2: <Realtek ALC887 (Internal Digital)> on hdaa0 (1p:1v/0r:0v)
pcm3: <Realtek ALC887 (Rear Digital)> on hdaa0 (1p:1v/0r:0v)
pcm4: <Intel Kabylake (HDMI/DP 8ch)> on hdaa1 (1p:1v/0r:0v) default
------------------

But selecting this device does not bring sound to HDMI.

I ain't sure this is a bug but I don't see what I can do more to make it works.
I tried many things and now I wonder if it's not a driver bug.

In the BIOS setting, there is a "SDIF out type" parameter which can be set
either at "SPDIF" or "HDMI". In both cases, there is no change.
