        I just noticed that the alsa control panel the HDMI was randomly setting itself to mute. I happened to catch it in mute, unmuted it, and now it works.

        Now to figure out what is muting the device without my permission…

        ETA also the sound device keeps switching randomly as well.

          If you do a general search for “hda ati hdmi” you will get lots of reports of problems with the HDMI port. For some reason, seems lots of Arch users have had similar problems. Not sure if their suggestions for fixes can give you some clue, but it’s worth checking out if you haven’t.

            Fn+F11 should be the mute keys

              Yes I know. I tried it when you first suggested it.

                Yeah, unfortunately, I’ve been trying fixes posted various places for the past two days. I think maybe it’s time to accept that this distro is just not going to be the one for me.

                  It’s a shame. Can’t think of a distro that will be as efficient on your box. Here’s a long shot: When I run Ardour (digital audio workstation) in Linux, I run the JACK audio server, which connects all the various audio software. It’s not geared towards the casual user, but you could have a go. If you install and run Qjackctl, you should have everything you need. I also use a program called Cadence to set up JACK audio, but not sure it will be helpful.

                    I know! It’s super frustrating. I did the live boot of AntiX and my first thought was “This is perfect. It’s super smooth and fast.” None of the other ones I’ve tried have even come close.

                    Hmmm ok, I will give it a try when I’m less frustrated. Thanks!

                        Do you have auto-mute enabled in alsamixer?

                          Hi amaroq,

                          You probably have heard this…audio is one of linux’s most problem prone pieces. Switching inputs and outputs with alsa is often tricky.

                          Alsa has a “tendency” to have things muted by default. anticapitalista mentioned how to fix this. You also have “automute” enabled in the internal sound card. I am not sure that it affects HDMI, but you can try disabling that with (I am told) the down arrow when you have moved to that choice.

                          I am a low level user and use a “helper” program that attempts to manage sound switching better than just using alsa. There are two available ones for the nonexpert audio user: PulseAudio (the current standard) and Pipewire, a presumptive replacement that is supposed to do better and has video roles also.

                          Both use Pavucontrol as a easy way to change the inputs and outputs and control the volume.

                          However, it sounds like you tried installing PulseAudio (you mentioned using Pavucontrol), so neither of those might help.

                          I had a problem with getting a USB connected headset detected by alsa and Pipewire/Pavucontrol – when using a “regular” debian version of a kernel. Using the closest antix kernels, the headset is detected fine. So you might try a different kernel (make sure it is labeled antix or nosystemd).

                          If that doesn’t work, you may need to “fix” the default sound card using instructions from the alsa project (https://www.alsa-project.org/wiki/Setting_the_default_device):

                          Setting the default device
                          Jump to: navigation, search
                          
                          Find your desired card with:
                          
                             cat /proc/asound/cards
                          
                          and then create /etc/asound.conf with following:
                          
                             defaults.pcm.card 1
                             defaults.ctl.card 1
                          
                          Replace "1" with number of your card determined above.

                          If THAT doesn’t work, unfortunately there are many other things that you might need to try before succeeding <g>.

                          There is more information on sound card selection at https://alsa.opensrc.org and at linux question answering sites such as unix.stackexchange.com or linuxquestions.com

                          If you find a solution, a post with the details is always highly appreciated.

                            Well, I went and tried a few other live distros, but they just suck! Is there a kernel you recommend retrying? (The download I tried was labled “antiX-21_x64-core.iso” if that helps.)

                            Do you have auto-mute enabled in alsamixer?

                            I’m not sure, how would I check that?

                            Thank you for the suggestions. I will try.

                              Go to antiX menu, Control Centre>>Software tab, then click the Package Installer button and install the newest 4.9.0 kernel. Afterwards you need to reboot and select that kernel to boot with.

                              BTW, its just a guess to run the older style kernel for an older laptop. I searched the Forum here for dv6 kernel to find what others were using. If it doesn’t work there are others here that are much more knowledgeable, but probably sleeping now…

                                  Oh, I see it now. Disabling it does not affect the behavior.

                                  Ok, I tried this, and it did not help my issue.

                                  I’m officially giving up. For now, I’ll be sticking with Ubuntu since the only other one I could get working was puppy linux and it was just… well… yucky.
