No sound after update on Lenovo X9-15

After updating and rebooting my system, a Lenovo X9-15 with Intel Lunar Lake running Fedora 43 KDE Desktop Edition, the internal speakers are no longer detected.
The kernel was updated to Linux fedora 6.17.8-300.fc43.x86_64.

lspci -k shows the audio hardware:

00:1f.3 Multimedia audio controller: Intel Corporation Lunar Lake-M HD Audio Controller (rev 10)
        Subsystem: Lenovo Device 233b
        Kernel driver in use: sof-audio-pci-intel-lnl
        Kernel modules: snd_sof_pci_intel_lnl, snd_hda_intel

There are bug reports on Ubuntu with the Lenovo X9-14. I don’t know if these issues are related:

I have found a workaround: Booting the old kernel Linux fedora 6.17.7-300.fc43.x86_64 brings back the audio device.

same issue. can rollback to Linux fedora 6.17.7-300.fc43.x86_64 however that kernel has its own stability issues.

Same on my Thinkpad X9 15 - booting 6.17.7-300 solves it for now.

5

Same here, Dell 14 Pro Premium. Rolled back to 6.17.7 for now.

Same on Lenovo Yoga Aura 7i (Lunar Lake). Not only do the interal speakers not show as a device (neither do the hdmi speakers show as a device), but worse: The usb-dock audio out does show as a device, but no audible sound output comes out when selecting this device. All of this is working on 6.17.7. I didn’t bother testing mic-input devices this time, but mic input was also gone in the late Fedora 42 updates, when the audio output was also broken.

Likewise. 9i audio stopped working and it keeps trying to connect to nearby airplay devices for audio. I’ll just get a pop up for “blah’s Macbook volume 0%” on my screen.

Edit: The strikethrough section is a separate bug, though still from pipewire.

Following the steps on this page didn’t work sadly. I think it’s a bug

People in Arch are having the same issue. I think it’s upstream and we just have to wait or use 6.17.7

6.17.9, which I installed today, has the same issue.
I downgraded to 6.17.7 again.

Same here, sadly.

6.17.10 from updates-testing fixes it.

Just updated to kernel 6.17.10 and unfortunately the only sound output is still “dummy” for me on the Thinkpad X9-15

EDIT:

False alarm, there was a GUI option where I had to enable the correct profile in cosmic settings. User error and maybe a bit of unpolished UI from DE still in beta.

Fixed on Yoga 9i with Lunar Lake :grinning_face_with_smiling_eyes:

6.17.12 is affected again on my device. Going back to 6.17.11.

Dang, really? Thank you for the warning; I’ll hold off.
