Is there still a kde-freebsd group?

I tried to subscribe to kde-freebsd@kde.org, but got no reply.

Here's my issue:

Audio problem with Intel HDMI/DP

System Settings correctly identifies all three channels, .i.e, Rear 
stereo, Front stereo, and HDMI/DP 8ch.
When I try any of the 3 Test buttons, it claims:

Error trying to play a test sound.

The system said: "No such driver"

dmesg shows three pcm devices:

dmesg|grep pcm pcm0: <Realtek ALC671 (Rear Analog)> at nid 20 and 27 on 
hdaa0 pcm1: <Realtek ALC671 (Analog)> at nid 33 and 24 on hdaa0 pcm2: 
<Intel Kaby Lake (HDMI/DP 8ch)> at nid 3 on hdaa1

None of the rudimentary steps in handbook Sound chapter work, i.e., beep 
-d /dev/dsp2.0, etc.

What driver does KDE believe is missing?

This is a fresh install, installed software from packages, but switched 
to ports trying to find audio solutions.


I put hw.snd.default_unit=2 in /boot/loader.conf Still no sound from hdmi.
