Hello, the audio chip Cannon Lake PCH cAVS ALC892 does not get recognized on my system. Only the HDMI devices are recognized. lspci shows the following audio device: 00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10) dmesg only shows: [ 189.559786] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_exit [i915]) [ 189.581395] input: HDA Intel PCH HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input20 [ 189.581503] input: HDA Intel PCH HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input21 [ 189.581628] input: HDA Intel PCH HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input22 [ 189.581711] input: HDA Intel PCH HDMI/DP,pcm=9 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input23 [ 189.581849] input: HDA Intel PCH HDMI/DP,pcm=10 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input24 ALSA-info file: http://alsa-project.org/db/?f=96102ee84f258d1cac83ed33795356550181511c There is a workaround availble: echo auto | tee /sys/devices/pci0000\:00/0000\:00\:1f.3/power/control echo 1 | tee /sys/devices/pci0000\:00/0000\:00\:1f.3/remove echo 1 | tee /sys/bus/pci/rescan unfortunately this doesn't work for me. The device never shows up. Sound on winX works fine on this device btw. I'm happy to assist with any attempts to make the sound work.
