Fresh manjaro KDE install - no sound card detected

Support Sound
1

Hello everyone, I just joined a new company on Monday and they have provided me with the new Lenovo laptop (T15) with the latest version of manjaro KDE (fresh install from monday).
I have no knowledge of Linux and after a day of research I allow myself to come and ask my question here.

I have a sound card in the computer but it is apparently not recognized at all by Manjaro KDE, the only time I managed to have sound on my computer is the time I used a headset with a usb plug.

When I don’t connect anything to my computer the volume icon in the bottom right corner is crossed out and when I click on it it says “no input or output device found”.

I tried a lot of commands but nothing worked.

Does anyone have an idea where the problem comes from and possibly a way to solve it?

Thank you all in advance,

Yours sincerely,
Florian

PS: 3 peoples in my company have the exact same problem, same computer, same Manjaro KDE version.

Hello and welcome,

You will need the 5.8 kernel installed and the newest version of pulseaudio-git from AUR.
http://aur.archlinux.org/packages/pulseaudio-git

See this comment and the first one in this discussion:
https://bbs.archlinux.org/viewtopic.php?pid=1922755#p1922755

The T13, T14 and T15 models from Lenovo seem to have the same Realtek ALC257 chip … so, it should help.

Hello and thanks for your quick reply !

As I mentioned in my topic i’m fairly new to Linux, i checked my Kernel version and it is :
5.7.17-2-MANJARO

I’ve already done a lot of configuration with the help of my team and I’m wondering if upgrading to version 5.8 would erase what I’ve done or cause a problem?

Thanks !

There can be multiple Kernels installed on the same machine. None will change any other configurations done by the user, nor delete them, just add the specifics of that kernel when booted with it.

Ok !

I found this command on the manjaro documentation : sudo mhwd-kernel -i linux419
I guess i need to change the linux419 by something else ? You told me to install kernel 5.8 so i suppose i need to run sudo mhwd-kernel -i linux58 to add the kernel ?

After that what do I need to do ?

Thanks in advance and sorry for the amount of questions, i’m really new to Linux and i don’t want to do anything wrong while changing this kind of things because that’s not my computer.

All good. It should boot into the new kernel right away, after reboot. If not, and the Grub Boot Menu is not visible, press Shift or Esc right after the BIOS loaded, and you will be able to select one or the other Kernel to boot into the system.

Neither we don’t want that :slight_smile:

So that’s the command to install kernel 5.8 ? And after that I do run “reboot” in my terminal and the newest kernel should be loaded by default ?

Ok so everything went fine with the kernel installation !
I know have this output :

[florian@florian-20s6cto1ww ~]$ mhwd-kernel -li
Currently running: 5.8.3-2-MANJARO (linux58)
The following kernels are installed in your system:
   * linux57
   * linux58

I can’t find pulseaudio-git on install/remove software menu,
I tried using pacman :

[florian@florian-20s6cto1ww ~]$ sudo pacman -Syu pulseaudio-git
[sudo] Mot de passe de florian :
:: Synchronisation des bases de données de paquets…
core est à jour
extra est à jour
community est à jour
multilib est à jour
erreur : impossible de trouver la cible : pulseaudio-git

Any idea ?

Update : I successfully installed pulseaudio-git and replaced the pulseaudio package by it.

I rebooted but still not audio, i’m not sure what should i do next !

Thank in advance

I edited my reply, thanks a lot

First of all, pulseaudio doesn’t seem to be running. Please run pulseaudio --start and see if audio works.

15

Did it, returned nothing and audio is still not working, “no input or output device found” when i check my audio icon

Btw thanks you for your kind help !

Could you run lspci -k and journalctl -b 0 | grep snd_?

lspci -k : https://pastebin.com/ZDYD2fmH

Please start journalctl -f, and then run sudo rmmod snd_sof_pci && sudo modprobe snd_sof_pci and see if anything is printed by journalctl.
