Solarmass In Budgie Control Center > Sound > Output Device = "HDMI / DisplayPort - Built-in Audio" and no other selection is possible. The blue bar animates according to music I try to play, but nothing is outputted to the TV attached to the HDMI cable.

      This is the working info from Linux Mint:
      $ inxi -Aaz
      Audio:
      Device-1: Intel Alder Lake PCH-P High Definition Audio
      driver: snd_hda_intel v: kernel alternate: snd_sof_pci_intel_tgl
      bus-ID: 00:1f.3 chip-ID: 8086:51c8 class-ID: 0401
      Sound Server-1: ALSA v: k5.15.0-78-generic running: yes
      Sound Server-2: PulseAudio v: 15.99.1 running: yes
      Sound Server-3: PipeWire v: 0.3.48 running: yes

        Jumpy what about Devices in Raven? Have you tried to activate it from there?

          $ systemctl --user stop pipewire-pulse.service
$ systemctl --user start pulseaudio

          You can certainly try these commands. They take effect immediately and don't persist past a reboot so they're safe to try and test out.

          That at the very least will help narrow down the problem.

            I noticed other issues with my Intel NUC and sent it for warranty repair. I will try to solve the sound issues and repost if needed when I get the unit back.

            4 days later

            I have the same issue. Solus Gnome, and I have used HDMI without any problems until after an update the sound is not working through HDMI (yes, I've checked HDMI is selected as output device).

            Okay Intel replaced my faulty NUC with a new one. But I still have no sound on Solus 🙁 Switching to LTS kernel did not make any difference.

            @kettu Terve kettu. MistÀ pÀin Suomea oot? PitÀsköhÀn vaan ootella jotain uutta pÀivitystÀ?

              Or maybe try installing sof-firmware and adding the snd_hda_intel driver to the blacklist:
              echo -e "blacklist snd_hda_intel" | sudo tee /etc/modprobe.d/blacklist.conf.

              Jumpy kernel alternate: snd_sof_pci_intel_tgl

              maybe this driver will work.
              Then show:

              inxi -Axx | grep driver
lsmod | grep sof
pactl info

                  I'll revisit the kernel config options in a future update. Maybe I made a mistake when I was trying to fix this in the past.

                    pomon After running echo -e "blacklist snd_hda_intel" | sudo tee /etc/modprobe.d/blacklist.conf nothing seems to change as I still get snd_hda_intel:

                      pomon Okay, I tried driver blacklisting again. This time I created the file and folder /etc/modprobe.d/blacklist.conf in Nemo with root privileges instead of using the command line. Now after rebooting, the intel driver is blacklisted successfully.

                      Now the following commands look like this:

                      I have sof-firmware installed, but is it not found?

                        ReillyBrogan How did I miss this?

                        user@user ~ $ systemctl --user stop pipewire-pulse.service
user@user ~ $ systemctl --user start pulseaudio

                        Well I tried it now and have sound. : Thank you and sorry.

                        PS: I have both pipewire and pulseaudio packages installed. Removing the unused package was not necessary. And no reboot was needed (infact you should not reboot) after running these commands for the sound to start working. Now I just need to figure out how to make the change persist a reboot 🙂

                            I was finally able to make the fix permanent like this:

                            $ systemctl --user disable pipewire-pulse.service
$ systemctl --user enable pulseaudio

                            What's the output of sudo dmesg? Upload it to pastebin or a similar site and post the output here.
