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.
