Sound /only/ via HDMI

Hello, all

I have FreeBSD 14.1 RELEASE on an AC-8 mini-PC:

  <https://bsd-hardware.info/?probe=170341d296>

And am trying to configure the sound card by the Cookbook:

  # dmesg | grep pcm
    pcm0: <Intel Jasper Lake (HDMI/DP 8ch)> at nid 4 on hdaa0

  # cat /dev/sndstat
    Installed devices:
    pcm0: <Intel Jasper Lake (HDMI/DP 8ch)> (play) default
    No devices installed from userspace.

  # pciconf -lv hdac0
    hdac0@pci0:0:31:3:	class=0x040100 rev=0x01 hdr=0x00 vendor=0x8086 device=0x4dc8 subvendor=0x0000 subdevice=0x0000
    vendor     = 'Intel Corporation'
    device     = 'Jasper Lake HD Audio'
    class      = multimedia
    subclass   = audio

Loading all the sound meta driver snd_driver, either from the prompt or
from rc.conf, has no effect, so that only the HDMI output is available,
whereas my PC also has a normal sound card with analog input and output
with 3.5 mm jacks.  Can you please help me troubleshoot this, and
configure the analog input and output the primary sound interface?
