    Can't get audio to work with new computer[SOLVED](maybe not what you thought)

    If you want to read to the end you can, but the fix was I installed Debian 12 KDE. Sound works. UPDATE:I installed Kubuntu 23.10 and the sound is now working. I also tried Fedora. The sound worked also, but I really don't like Gnome desktop.
    I guess this Chinese computer is just not that easy to work with.
    Any way, thanks for all of your suggestions.


    I have a new computer that has a proprietary MB. I was finally able to get the internet working and now I need to get audio going. Usually it's pretty straight forward, but not with this computer. I've used Ubuntu in the past, but it's been awhile so I'm a newbie with Kubuntu. The reason I'm using Kubuntu with this computer is that it's configured with secure boot and can't be disabled. It was Ubuntu or Red Hat. Now to my problem. I'm guessing I have a driver problem, but have no idea how to find out what driver I need, if in fact I do need a new one. I have external speakers plugged into the audo out port on the computer. When I use Pulse Audio volume control, the status bars show there is audio happening. Just no sound. I am dual booting with Windows 11 and the audio works just fine. Any help with this is very appreciated. Here are my specs:

    You may need to install firmware-sof-signed. It might not hurt to make sure that you have linux-firmware installed as well.

    Are you sure it can't, or is it locked by your employer?
    The distro is sort of unrelated here, Ubuntu and Kubuntu are the same OS, and both support Secure Boot

      firmware-sof-signed was installed, firmware was not. I installed firmware, but no joy. The Plasma volume control gui recognizes the sound card and shows there is activity.

      Secure boot is locked by the manufacturer. I talked with them about it. Can't be disabled.

      I only mentioned Kubuntu because I like KDE as a desktop

          I read through all of that. Most went over my head, but I tried a few suggestions with no joy. I don't believe the OP found any joy either. Maybe Linux can't work with this computer?

            On 'problematic' systems, often trying out a much more current or bleeding edge distro via a live session is warranted.
            There are more moving parts involved, so the latest kernel, audio stack, and firmware often need to go together.
            For example:
            My Lenovo c13 Chromebook (AMD Ryzen™ 5 3500C) has no audio support before a 6.3 kernel, but it isn't as simple as just getting a new kernel - that is easy. All the other sound related parts also need to be a bit more current as well. I can use Kubuntu on that device now, with 23.10, but that didn't help me about a year ago, so I went with Fedora at the time, which has all the things I need.

              Sometimes techs "misconstrue" Secure Boot SHOULD NOT be disabled as CANNOT be disabled, because of Windows.

                On this computer there is no secure boot choice in the bios settings. No, they were correct, it cannot be disabled.

                  I downloaded an Fedora iso to try. It's one distro I've never tried. I hope it works.

                    On some computers, such as my HP laptop, it's hidden behind an admin password.

                      If you want to try a distribution that includes a recent kernel: why not try Kubuntu 23.10 (kernel 6.5.x) and possibly replace your 23.04 afterwards?

                        I'll probably give this a try.
