No sound on fresh Kubuntu 25.10

[smilingmonkey]

Hi everybody !

Ubuntu Version:

$ fastfetch -s Host:OS:Kernel:DE --logo-type none
Host: HP SpectreXT Pro 13-b000 PC (0782100400204E00000330100)
OS: Kubuntu 25.10 (Questing Quokka) x86_64
Kernel: Linux 6.17.0-5-generic
DE: KDE Plasma 6.4.5

Problem Description:

After a fresh install of Kubuntu 25.10 on my laptop, I don’t have any sound. The Plasma applet says that no input device has been found.

Please note that Ubuntu Desktop 25.04 (GNOME) was previously installed on this laptop and the sound worked fine.

Relevant System Information:

It seems that my device is detected by the driver is not loaded :

$ inxi -A
Audio:
  Device-1: Intel 7 Series/C216 Family High Definition Audio driver: N/A
  Server-1: PipeWire v: 1.4.7 status: active

$ lspci -nnk |grep -A 2 Audio 
00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)
        Subsystem: Hewlett-Packard Company Device [103c:1888]
        Kernel modules: snd_hda_intel

$ lsmod |grep snd_hda_intel

What I’ve Tried:

I tried to load the module but got an error :

$ sudo modprobe -v snd_hda_intel
insmod /lib/modules/6.17.0-5-generic/kernel/sound/soundcore.ko.zst 
modprobe: ERROR: could not insert 'snd_hda_intel': Exec format error

$ sudo dmesg |tail -n 1
[ 3169.137978] Invalid ELF header magic: != \x7fELF

I don’t really know what to do next and would need some help to go forward.

Thank you !

Exec format error

This is extremely weird and indicates that this module was not built for the CPU architecture you are running, did you download the file separately from somewhere or anything similar?

No, I just installed Kubuntu

Based on your message, I reinstalled the package “just in case” with :

sudo apt --reinstall install linux-modules-6.17.0-5-generic

And the sound now works after reboot ! Sorry, i should have tried that before posting

Thanks for your time and message @ogra
