Sound not working after update Lenovo Legion 7

Question

After I updated my software some weeks ago the audio of my device Legion 7 16ACHg6 is not working anymore on Ubuntu 22.04.3 LTS x86_64.

There has been lot of discussion about this problem in past times (bugzilla thread #1, bugzilla thread #2, lenovo thread, etc.) but since few years the problem was resolved and it is showing up again. It seems to be possibly related also to the fact that i am dual booting with Windows 10.

Some internal specs

Answer 1

A possible option would be to downgrade kernel to the version where audio was working, e.g. 5.19.x.

Answer 2

How are you doing?

I have experienced the same error with version 6.2.0. I tried to fix it but I couldn't fix it at all in this version. So I was forced to change the kernel version. In the following web kernel we can see the stable kernel versions, as I didn't want to go back to 5, I saw that the long term version was 6.1.55.

It is very important that when you install the new kernel version, when you reboot the computer, enter the recovery menu and make sure to boot with the kernel version installed. When the computer boots to make sure you are on the correct version, open the terminal and run the following command to find out what version you are running:

uname -r

Once you know you are running on the correct version, just stabilize it with the drivers, test most of the apps you use daily and if all goes well, I would advise you to delete the kernel versions that were malfunctioning, so you have a clean environment to continue with your tasks and avoid any eventual initialization of some version that was running wrong.
