No Sound (HP Envy x360 15)

[filiusDei]

Hey everyone,

after installing the current version of Kubuntu on a new notebook (HP ENVY x360 15-ey0157ng) unfortunatley there is no sound at all. Headphones are working though.

cat /proc/asound/cards
​

says

0 [Generic        ]: HDA-Intel - HD-Audio Generic
                     HD-Audio Generic at 0xd05c8000 irq 91

                     HP-HPENVYx3602_in_1Laptop15_ey0xxx-Type1ProductConfigId-8A31

Any help or tips would be very much appreciated.

Have you checked System Settings > Audio and clicked the Test button? You can also verify that the Speakers volume isn't set to 0%.

[Schwarzer Kater]

Welcome!

Did you already check in System Settings -> Audio that everything is correct there?

You could also post your Kubuntu version and the output of e.g.
the whole Audio device: section of lscpci -v or just lspci -v | grep -Ei 'audio|snd'
and
pactl info

Yes. The test buttons are not working and volume is set to 100 %

Thank you

The Speaker test buttons in the System Settings are not working.
It's the latest version 23.04 and here's the ouitput:

lscpci -v Command 'lscpci' not found, did you mean: command 'lspci' from deb pciutils (1:3.9.0-4) Try: sudo apt install <deb name>

typo, the command is actually lspci, someone left a stray letter in there

A quick search dive seems to indicate that audio for this hardware isn't well supported before about kernel 6.2.3-ish, and even then may require patches -- the so-called Ubuntu "mainline" kernels likely may not work.
So any Ubuntu-based distro ourtside of Pop OS won't have a new enough kernel and audio stack, at least until 23.10 comes out.

A thing to try would be a live session of Fedora 38, Endeavour, Pop OS, or similar setup with a more current kernel. At least you would be able to tell fairly quickly.

I don't know if it is related or not, but my 'converted' AMD based Thinkpad Chromebook only got sound support with a later 6.2 kernel, and even then it took extra configuration and custom things above my head. Audio is working for me ootb in Fedora 38 KDE (Kinoite, to be precise). It also worked ootb from an Endeavour OS (Arch) live ISO. Not sure if this is peculiar to the SoC nature of Chromebooks, but the audio hardware seems quite similar to what you have. Renoir AMD, snd-sof stuff, and even Intel kernel modules.

Oh-oh… Mea culpa.

The sentence should have been:
… [could post] the Audio device: section(s) [only] of lspci -v …

(-> you could copy such ouputs and put them within CODE tags in your post)

[…]

Thank you so much. This information is really helpful, but also kinda unpleasant and except for the sound, everything works perfectly. In this case, Fedora 38 could definitely be worth a try. We'll see how it works

Audio is working for me ootb in Fedora 38 KDE (Kinoite, to be precise)

There's a Spin called "Fedora KDE Plasma Desktop 38" and the mentioned "Fedora Kinoite 38" available. That's a little confusing, because both are using the KDE Plasma Desktop, aren't they? Do you know what's the difference and you would recommend Kinoite right?

[Schwarzer Kater]

Fedora Kinoite is an "immutable" distribution (https://distrowatch.com/search.php?o...=Active#simple).

To test if your audio hardware works with a newer kernel I would suggest the standard Fedora KDE Spin - if you really want to use Fedora…

Thanks. "immutable" means that it's not possible to make any changes, right? Is this the case for Fedora at all, not only for Kinoite? Your link doesn't mention Kinoite, but only Fedora in general and here as well: https://distrowatch.com/table.php?distribution=fedora

The desire is definitely to use Kubuntu, but without sound it doesn't makes sense. So a temporary solution will probably be needed until 23.10 is available.

Update: Unfortunately, Fedora doesn't work ootb as well

[filiusDei]

If Kubuntu 23.04 does not work with your audio hardware, you could also try TUXEDO OS 2 (Ubuntu-based with KDE Plasma and a recent kernel) or openSUSE Tumbleweed KDE (rolling release like Arch/EndeavourOS with very recent kernel) - or Fedora KDE as mentioned.
Personally I would prefer them especially to Pop!_OS (a GNOME distribution…)- and they are all easier than Arch/EndeavourOS for newer-to-Linux-users. Or try Garuda KDE for an Arch-based distribution.

Thank you. So you would recommend TUXEDO OS 2 or openSUSE Tumbleweed to newer users, right?

[claydoh]

Thanks. "immutable" means that it's not possible to make any changes, right? Is this the case for Fedora at all, not only for Kinoite?

No, it is possible to make changes, but it isn't a system-tinkering type of system so much (though that is exactly what I am doing with it at the moment, lol).
I should not have mentioned it anyway, as it does not have a live ISO iirc, and just add confusion.

Any Fedora 38 live image, or any other live iso with at least a 6.3.x kernel is worth trying, for your specific audio hardware, to give a test run before actually installing.

r openSUSE Tumbleweed to newer users, right?

No, and yes on this one. it is always 'bleeding edge", a so-called rolling release with much more constant level of updating, and the potential bugs and oddities that this comes with. That may or may not be what you might enjoy. But it will have a bit better hardware support for the newest stuff. Tumbleweed is much more like Arch Linux.

Fedora (the normal one) is more like Ubuntu, it is just enough ahead, in terms of kernel versions at the moment.

[claydoh]

you could also try TUXEDO OS 2 (Ubuntu-based with KDE Plasma and a recent kernel)

Tuxedo is using KDE neon's Plasma packaging, and for the OP's purpose, the kernel is not new enough, methinks. Still worth a checkout, though.

Any Fedora 38 live image, or any other live iso with at least a 6.3.x kernel is worth trying, for your specific audio hardware, to give a test run before actually installing.

Alright, thanks. Fedora 38 KDE isn't working. It shows all the audio devices and even the bar moves when listening to something, but there is still no sound. Maybe this integrated Bang & Olufsen audio stuff needs additional drivers to work? HP is offering those only for Windows though.

Edit: Same with EndeavourOS and Pop!_OS. What's left to try? OpenSUSE Tumbleweed and Garuda KDE? Anything else?

Does it make sense to post this issue in the askubuntu forum as well? Because we probably can't solve it with Kubuntu anyway, right?
