After ubuntu 19.04 update, sound card cannot be detected
I have used software update. After then there's no sound. After spending hours reading similar problems I realize that none of them (including reinstalling alsa and pulseaudio) works for me.
Using
lspci -v | grep -A7 -i "audio"
I get the following results:
00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)

It seems that despite the sound card does exits, the system cannot installing a proper driver. Following https://help.ubuntu.com/community/SoundTroubleshooting I tried to instally snd-hda-intel driver but it returns:
sudo modprobe snd-hda-intel
modprobe: FATAL: Module snd-hda-intel not found in directory /lib/modules/5.0.0-29-generic
I then visit https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+packages but I don't know how to install the proper .tar.gz as a driver (possibly for oem-audio-hda-daily-dkms_0.201907080246~ubuntu19.04.1.tar.gz ?) Can someone help me to work it out? Thanks!
Update1
dkms status
returns nothing. Tried sudo apt update
and upgrade
does not solve the problem.
Here is what
lspci -knn | grep Audio -A3
returns:

found this solution here https://superuser.com/a/1509313/1151609
it worked for me
Here is a copy of the original post from hopeseekr
sudo vim /etc/default/grub
Find GRUB_CMDLINE_LINUX_DEFAULT and add snd_hda_intel.dmic_detect=0 to the end
of it. (ex: GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3
snd_hda_intel.dmic_detect=0")
sudo grub-mkconfig -o /boot/grub/grub.cfg
Reboot the system.
