Pop! _OS, Intel sound card does not work after updating Linux kernel

This article was first published in 2020 on my previous blog. I’m re-posting it here as part of migrating old content, since kernel-related issues like this can still be relevant.

The problem

If your intel sound card does not work after updating Linux kernel you can revert back the kernel.

In my case, the sound card stopped working after installation the kernel linux-image-5.3.0-7642-generic

These steps can help you to revert back the kernel

Check your current kernel version

uname -a

Check the list of available kernels

ls /boot

So, my previous kernel is linux-image-5.3.0-7625-generic

Let’s revert back the previous kernel

sudo kernelstub -v -o "quiet loglevel=0 systemd.show_status=false splash" -k /boot/vmlinuz-5.3.0-7625-generic -i /boot/initrd.img-5.3.0-7625-generic

sudo reboot

Check your kernel version again

uname -a

It should be your previous kernel.
After that, the sound card should work.

I hope this problem will be fixed in the next kernel version.
