Bug ID: 267817
Summary: No sound with Intel Comet Lake PCH-LP cAVS sound card
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me

Hello everyone,
With FreeBSD 13.1-RELEASE-p3 on a PC which has an Intel Comet Lake PCH-LP cAVS
sound card the sound doesn't work.
>From the hardware ID returned by pciconf -lv | grep -B3 multimedia , and in
accordance with this file
(https://github.com/freebsd/freebsd-src/blob/master/sys/dev/sound/pci/hda/hdac.h)
I have the impression that the card could be taken into account
(HDA_INTEL_CMLKLP).
# pciconf -lv | grep -B3 multimedia
hdac0@pci0:0:31:3: class=0x040100 rev=0x00 hdr=0x00 vendor=0x8086
device=0x02c8 subvendor=0x1e39 subdevice=0xb993
vendor = 'Intel Corporation'
device = 'Comet Lake PCH-LP cAVS'
class = multimedia
Here is the return of cat /dev/sndstat:
# cat /dev/sndstat
Installed devices:
pcm0: <Intel Kaby Lake (HDMI/DP 8ch)> (play) default
No devices installed from userspace.

And here is the line I have in /etc/rc.conf:

I don't know what other information might be relevant, but feel free to ask me
if any other information might be useful.
