No sound devices after fresh install

Issues & Assistance
21

Can you try installing sof-firmware as some other posts have suggested? Run sudo mkinitcpio -P after and reboot

Also, run sudo cachyos-bugreport.sh and send the link here so we can take a look at your system logs.

22

Sof-firmware is installed. 2024.06-01

Oh I see it now. Try using an updated kernel like the default. sudo pacman -S linux-cachyos, you seem to be hitting a kernel regression same as Missing sound outputs on a fresh install - #7 by acceleration3

edit: The LTS kernel is also affected, thats why it is also broken.

Edit 2: rt-bore seems to be updated to for 6.11.

24

Had I seen this thread I would have shared my findings sooner.
I can confirm 6.11+ kernels fix this issue.

25

My forum account was blocked yesterday for too many posts. So I had to wait for 20+ hours to continue.

  1. I got this issue right after the fresh install on the DEFAULT kernel.
  2. I tried bore 6.11 kernel, LTS kernel, Arch Linux kernel - and the result was negative, The issue was still here.
  3. I installed pulseaudio, the installation process automatically removed pipewire-pulse, and IMMEDIATELLY I saw all my AUDIO devices, and got sound on every kernel. I use 6.11. bore kernel right now.
  4. I donā€™t like the solution with removal of pipewire files. But found no other solution in the Internet.
  5. It is useless to read manuals, wiki, etc, if kernels are really broken.
    So what is the right way to get rid of the issue? What is its reason? Shall we set up pipewire manually right after the installation? Or what?
26

No. At least for me.

UPD
Newly fresh install on the main SSD (Sata) to be used as a main distro.
My kernel is now:
āÆ uname -a
Linux cos 6.11.0-1-cachyos #1 SMP PREEMPT_DYNAMIC Tue, 17 Sep 2024 14:37:39 +0000 x86_64 GNU/Linux
The same issue! No sound devices.

28

Iā€™m on a FRESH install now. Just right after the installation.
I use KDE, default kernel. I touched nothing. It is newly fresh not to break anything by myself.
āÆ uname -a
Linux cos 6.11.0-1-cachyos #1 SMP PREEMPT_DYNAMIC Tue, 17 Sep 2024 14:37:39 +0000 x86_64 GNU/Linux

Not only no sound. NO DEVICES visible. I can resolve this issue by installing pulseaudio, I wrote this above. But I want to know the real reason of the issue and resolve it in the right way.

speaker-test
speaker-test 1.2.12
Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 128 to 2097152
Period size range from 64 to 1048576
Periods = 4

Weird. I got Endeavour OS on the same PC, and it works smoothly out of the box on KDE.

34

No sound. I hear nothing.

36

Maybe there is a need in the developers help. A person said above that kernels are broken. Maybe kernels, maybe pipewire+KDE - who knows?

38

My PC is a DESKTOP.

40

How to send a bug report? I have no idea.

42

It is about AUDIO Devices, not speakers. They are registered in the OS but now showing up. I published all the info above. No errors.

44

I FOUND THE ALMOST solution!

  1. I ended my Wayland Session and changed to X11 Session.
    MIRACLE! All the devices are back in System Settings and Taskbar!
  2. I ended X11 Session and changed back to Wayland.
    EVERYTING WORKS! Speaker test also works.
    But this solution doesnā€™t mean there is no bug. The BUG is still alive. Dear developers, please, kill it! The couple - KDE - Wayland is still buggy!
    SOMETIMES IT WORKS, Sometimes - NOT!
46

The issue is still here. Sometimes everything works, sometimes not.

49

What I see, KDE is a bit unstable on cachyos kernels, Wayland or no wayland. The desktop loads too long, the taskbar can be distorted, apps can unexpectedly freeze. Double icons in the task bar. Why? Seems the idea is good but the implementation is weak. But speed is good. ) Too small a team. Too many desktop environments. Letā€™s see what will come out of the venture.

50

I have external speakers. Donā€™t forget, I have Endeavour OS installed. It works smoothly. The bug is inside the OS.

52

Without any logs or equal, nothing can be done. sudo cachyos-bugreport.sh

53

Logs are published here (Sorry, it seems, I posted them in the wrong place):

What is moreā€¦ Live media (before installing CachyOS on a hard drive) doesnā€™t see audio as well.
