    [DESKTOP] Is there a way to revert linux kernel version?

    Hello,

    Earlier this month my motherboard died. My computer build at the time was almost 10 years old so decided to buy new parts; I now have i7 10700k on a MSI MAG z790 Tomahawk. I also bought a 1TB m.2 drive for my linux install

    The problem is that after installing Kubuntu, the speakers stopped working. I see a "Dummy Device". I found a sticky on this forum where someone mentioned that a kernel update broke a lot of sound devices. Running the version of Kubuntu live from USB doesn't break the audio device. The kernel version on that is 5.4.0-26-generic. My current kernel version is 5.11.0-27-generic. I think that during installation it downloaded the recent update of the kernel.

    My knowledge of kernel isn't that advanced yet. Wondering if it's possible to revert the kernel version back or is there an easier fix?

    Thanks

    You *should* have the option to boot to the original 5.4 kernel in your grub menu, so testing the original kernel should be quite simple.


    Code:
    $ apt search linux-image | grep installed

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

linux-image-5.11.0-25-generic/focal-security,focal-updates,now 5.11.0-25.27~20.04.1 amd64 [installed,automatic]
linux-image-5.11.0-27-generic/focal-security,focal-updates,now 5.11.0-27.29~20.04.1 amd64 [installed,automatic]
linux-image-5.4.0-81-generic/focal-security,focal-updates,now 5.4.0-81.91 amd64 [installed,automatic]
linux-image-generic/focal-security,focal-updates,now 5.4.0.81.85 amd64 [installed,automatic]
linux-image-generic-hwe-20.04/focal-security,focal-updates,now 5.11.0.27.29~20.04.11 amd64 [installed,automatic]

    If you don't have a 5.4 here, just install the linux-image-generic package, which will pull in the 5.4 kernel and modules, etc.

    sudo apt install --install-recommends linux-generic
    If you are happy, and do wan to get rid of the 5.11 kernels altogether
    Code:
    sudo apt remove --purge linux-generic-hwe-20.04 linux-oem-20.04 linux-hwe-* linux-oem-* linux-modules-5.1* linux-modules-5.8.0-* linux-modules-5.6.0-* 
sudo apt autoremove
    I don't recommend this, as it is a good idea to keep the current kernel in case the problem is not the HWE kernel at all, and to have a good fallback

    Updating normally will keep both the 5.4 and the 5.11 with all the security updates and fixes. Down the road, the 5.11 will be upgraded to 5.13, however. The 5.4 will stay put.

      The thing is my speaker doesn't get detected at all unless I use 5.4. Is there a way to boot into 5.4 automatically instead of 5.11 without deleting any of the kernels?

      I still don't know why my speakers don't work in 5.11.0.27-generic, what should I look into fix this?

        When you say "speaker" are you actually referring to your audio chip? You can plug different kinds of speakers into the audio out jack on the side of your computer.

        You can determine IF your audio chip is being recognizes by looking for the "multimeida" section in the "sudo lshw" output. Mine shows:
        Code:
        [FONT=monospace][COLOR=#000000]  *-multimedia [/COLOR]
             description: Audio device 
             product: 7 Series/C216 Chipset Family High Definition Audio Controller 
             vendor: Intel Corporation 
             physical id: 1b 
             bus info: pci@0000:00:1b.0 
             version: 04

             clock: 33MHz 
             capabilities: pm msi pciexpress bus_master cap_list

             resources: irq:34 memory:d3610000-d3613fff
[/FONT]

        and shows my audio driver to be snd_hda_intel. Yours may be different. If you cannot find an audio section in your lshw listing then you can assume that your audio chip wasn't recognized and hence neither will any speakers plugged into your audio out jack work.

        Using lsmod I can show my audio chip driver, and drivers dependent on it, are installed and working:
        $ lsmod | grep snd

        If I use the modinfo command I can list the snd_hda_intell driver and the params (parameters). It also lists the snd driver.

        I can add or edit the snd_hda_intel.conf and snd.conf files residing in /etc/modules.d directory to control how the kernel reacts to the modules when they are loaded. These conf files are where you make adjustments to the "param" settings listed in the modinfo output.

        $ modinfo snd_hda_intel
        Code:

        You can use "modinfo" to show params for what ever driver is listed for your audio chip in the lshw listing.

        To the best of my knowledge all audio chips require the snd module.

          I still don't know why my speakers don't work in 5.11.0.27-generic, what should I look into fix this?
          You can install and use Grub Customizer.

            Thanks GreyGeek, I guess I meant to say audio chip instead of speakers as the speakers themselves work fine. They worked before the upgrade, and they worked fine when I run kubuntu from a live session. Which leads me to encountering to another problem; I said earlier that I was able to get audio when kernel version 5.4.0-26-generic is used. This however isn't the case and it seems like I may have a completely different issue instead, since loading kubuntu to use that kernel version from grub doesn't fix my audio issue at all.

            These are the devices I'm seeing in Audio Volume Settings:

            The DisplayPort 2 is just a monitor that's connected to my graphics card and doesn't have any speakers. Whenever I play video I notice the Digital Output bar animating indicating that sound is being played but I can't hear it; my speakers are turned on and the volume dial is up. As another test, I tried running kubuntu from USB and everything worked fine, I can play hear audio through my speakers.


            I did run the lshw command and found two devices with the snd_hda_intel:

            I haven't tried tweaking the conf file as I'm not sure what to tweak or what's causing this problem, so left it at that to avoid breaking anything else. However, given all that is said, everything should be working given that my audio chip drivers are being listed, right?

            Edit: So I loaded Kubuntu from live USB again and noticed that the audio output was named differently. It was called "line out". After installtion I don't see this "line out" option anywhere and it's instead replaced with what's currently called Digital Output. I've found some solutions online that suggested to edit the alda-base.conf files and to remove timidity daemon and neither solutions have worked so far

              Decided to try and plug the speaker cable to the headphone jack at the front of my PC. I can now hear audio again! PulseAudio detected it as headphones being plugged in. Ideally I would prefer to have the connection be at the back motherboard ports so that the cable is out of the way. However this will have to suffice for now until I can find a fix. I'm guessing that there's some incompatibility somewhere with regards to my motherboard's audio input connections.

                Instead of using digital stereo, try switching to analog stereo (configuration). I remember having that problem once and that's how I fixed it.
