This should do it, but again, this is for the 5.11 kernel:

Code: Select all

grep CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH /boot/config-`uname -r`

After reinstalling a 5.11 kernel, I tried this command : no help, unfortunately

PROBLEM (half) SOLVED

So I figured I'd try these procedures on a fresh Ubuntu 20.04. I installed it, then ran

Code: Select all

apt install linux-oem-20.04
Which installed the 5.6 kernel as planned.

Then I just had to select this kernel as default (using this method), reboot, and everything was working fine, nothing more !

Thank you so, so, so much for your precious time, MrEen !

Nicely done Kalytis! :D

I can only guess Ubuntu messed up the 5.11 kernel that should have fixed this. It may get straightened out soon-ish.

And thanks for mentioning the kernel only was enough for you. Next user with that system we'll try the same with first.

Hi !

Can't help but notice that you've been quite discreet on this forum recently, MrEen, I hope everything is going good for you !

Anyway, just an update. For some reason, I stopped getting any sound with my 5.6.0-1056-oem kernel, installed from "apt install linux-oem-20.04". I figured I'd pop an eye on the thread with a similar problem from mine, and noticed hglee mentionned a compatible 5.10 default kernel.

Unsure of the outcome, I went "apt full-upgrade", which installed a 5.10.0-1029-oem kernel. Then went in my /etc/default/grub, and set GRUB_DEFAULT to 0, as explained on this website that I mentionned earlier.

Rebooted, and my sound worked again ! Now running a 5.10.0-1029-oem kernel.

Hope this can help other people whose computer stopped producing any sound !

Hello Kalytis,

I have the same hardware, same kernel but no sound. There should be something else different...
Could you help me finding these differences ?

do you have the list of things you installed, ... ?

thanks
