Ubuntu 18.04 - Lenovo Thinkpad Carbon sound card not recognized since firmware update
Solution 1
Thanks to all of you that answered and commented my question. While waiting for an answer here, I found someone on the web with the same problem that was advised to go and look here : https://bugs.launchpad.net/ubuntu/+source/linux-oem-osp1/+bug/1864061/comments/3. The two steps proposed there solved the issue :
- add
options snd-hda-intel dmic_detect=0
in the configuration file/etc/modprobe.d/alsa-base.conf
- add
blacklist snd_soc_skl
in the config file/etc/modprobe.d/blacklist.conf
As this fixed my issue, I do not know if other solutions work as well, but I'm sure they do :). Thanks again!
Solution 2
Edit /etc/default/grub
as root and add the next kernel parameter:
GRUB_CMDLINE_LINUX="snd_hda_intel.dmic_detect=0"
Save and then execute in terminal:
sudo update-grub
And restart...
The latest kernel update (5.3.0-42), while trying to fix things end up breaking them... This should fix it up again....
Ubuntu 18.04 audio disappeared after update

I recently updated firmware on my Thinkpad Carbon X1 (last gen, 7th I guess) and since (I'm not sure it is the cause of my problem, but it happens simultaneously), I only have a "dummy device" in sound configuration panel on Ubuntu 18.04. I tried a lot of stuff suggested around the web and still, the result of
aplay -l
is alwaysno sound card detected
. The output oflspci -nnk | grep -A2 Audio
is :Audio device [0403]: Intel Corporation Device [8086:9dc8] (rev 11) Subsystem: Lenovo Device [17aa:2292] Kernel driver in use: snd_soc_skl
Any suggestion how to fix this ?
