Dear Ubuntu Support!


A few months ago after an official update the sound on my laptop was not working at all.
I have completely reinstalled, using Ubuntu 24.04.2 LTS and during the install, sound was working, but the first time I connected to WiFi and accepted the builtin "Software Updater" recommended update, it went wrong again. No sound at all. Via Bluetooth headset it is still working.

In Settings->Sound Output section, the "Output Device" is "Dummy
Output". Of course not working by clicking Test button next to it. It
should be "Family 17h/19h HD Audio Controller".

I think the problem is: There should be linux-modules-
extra-6.11.0-26-generic under /lib/modules/ folder. But I can see only
module without "extra". I have seen some info on internet, that kernel
modules are shipped in two packages, normal and extra. Most of the sound
driver modules are shipped in the extra.

I could not install the module, so I can not verify this assumption. (Kernel downgrade also works, but I have not tried.)
I still have a faulty laptop sound. I can not solve this issue.

I have found the most helpful discussion here:
https://superuser.com/questions/1816355/how-to-install-sound-driver-on-
ubuntu-20-04


BTW: During 24.04.2 install I had to disable WiFi, otherwise it was failing without Error message, I could see only some segfault from Python3.10. But this is another bug.


Best Regards,
Gabor
