Re: freebsd hdmi audi

Thank you for a response, it's the first in a decade for this issue.

I have two HP's, a Slimline with an i7, and an Envy with an i7. Both are 
small towers (desktops).

I too use drm-kmod and x11.

dmesg:

hdacc0: <Realtek ALC671 HDA CODEC> at cad 0 on hdac0
hdaa0: <Realtek ALC671 Audio Function Group> at nid 1 on hdacc0
pcm0: <Realtek ALC671 (Rear Analog)> at nid 20 and 27 on hdaa0
pcm1: <Realtek ALC671 (Analog)> at nid 33 and 24 on hdaa0
hdacc1: <Intel Kaby Lake HDA CODEC> at cad 2 on hdac0
hdaa1: <Intel Kaby Lake Audio Function Group> at nid 1 on hdacc1
pcm2: <Intel Kaby Lake (HDMI/DP 8ch)> at nid 3 on hdaa1

kde5 as well as plasma6-plasma correctly identify all three sound 
outputs, but when I press the Test button (in system settings Audio) it 
says there's a driver missing (but it doesn't identify the driver)

X does provide a good kde5 or 6 desktop, but can't output sound to any 
of the three outputs. From the command line, I can output to the front 
or rear realtek outputs, but not hdmi.

    BTW, I've been using FreeBSD since 1.x days.

These same systems give me sound on every output on linux mint, kde 
neon, debian12.

the x11 anomaly i mentioned was regarding a new gmktec k8 (amd w radeon 
780M graphics)

I'm running 14stable, but I've had this issue since 2017 (Dell Inspiron 
3668 (i3).
