dmesg

Hi,

I have a Intel NUC PPYH:
https://ark.intel.com/products/87740/Intel-NUC-Kit-NUC5PPYH

I don't get any audio from the HDMI connected to my LG HDTV (video is working
fine). Tried firefox (youtube) and kodi. No audio is coming out from TV
speakers.

At "/boot/loader.conf" I have:
snd_hda_load="YES"

At "/etc/rc.conf" I have:
kld_list="/boot/modules/i915kms.ko"

"cat /dev/sndstat" gives:
Installed devices:
pcm0: <Realtek ALC283 (Analog)> (play/rec)
pcm1: <Realtek ALC283 (Front Analog Headphones)> (play)
pcm2: <Realtek ALC283 (Internal Digital)> (play)
pcm3: <Intel (0x2883) (HDMI/DP 8ch)> (play) default
No devices installed from userspace.

So, at "/etc/sysctl.conf" I have:
hw.snd.default_unit: 3

My user is in group: video

Currently, I am using the intel Xorg driver. I have also tried the modesetting
Xorg driver, still no sound. I have also tried "drm-stable-kmod" with same
results.

System is: FreeBSD 12.0-RELEASE r341666 GENERIC  amd64
Pkg is: drm-fbsd12.0-kmod-4.16.g20181215

I am attaching the dmesg output.

Since I am planning to use this NUC as HTPC, having no HDMI audio is a no-go
for me... :(
