1. Please describe the problem: Audio stops working. Sounds card not visible. 2. What is the Version-Release number of the kernel: 6.17.8 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Yes. Worked on 6.17.7 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Update to 6.17.8, reboot, sounds stops working. Reboot with 6.17.7 and sound works. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Reproducible: Always

This also happens to me, Fedora 43 / Lenovo Yoga 9 Aura / Intel Ultra 7 258V Kernels 6.17.7 and earlier work, but 6.17.8 does not. Looking at dmesg, in working configurations, after the topology file is selected, there are many lines related to "cs35l56", [ 11.901861] sof-audio-pci-intel-lnl 0000:00:1f.3: Firmware paths/files for ipc type 1: [ 11.901868] sof-audio-pci-intel-lnl 0000:00:1f.3: Firmware file: intel/sof-ipc4/lnl/sof-lnl.ri [ 11.901869] sof-audio-pci-intel-lnl 0000:00:1f.3: Firmware lib path: intel/sof-ipc4-lib/lnl [ 11.901870] sof-audio-pci-intel-lnl 0000:00:1f.3: Topology file: intel/sof-ipc4-tplg/sof-lnl-cs42l43-l0-4ch.tplg [ 11.902431] sof-audio-pci-intel-lnl 0000:00:1f.3: Loaded firmware library: ADSPFW, version: 2.13.0.1 [ 12.151661] sof-audio-pci-intel-lnl 0000:00:1f.3: Booted firmware version: 2.13.0.1 [ 12.181728] cs35l56 spi-cs35l56-left: supply VDD_P not found, using dummy regulator [ 12.181771] cs35l56 spi-cs35l56-left: supply VDD_IO not found, using dummy regulator ...

Happens to me too. Dell 14 Pro Premium Intel Ultra 7 258V 6.17.7 is fine, 6.17.8 broke it.
Want to give https://koji.fedoraproject.org/koji/taskinfo?taskID=139136604 a try and see if that fixes it?
(In reply to Justin M. Forbes from comment #5) > Want to give https://koji.fedoraproject.org/koji/taskinfo?taskID=139136604 a > try and see if that fixes it? Give it (6.17.9rc2) a try, but doesn't fix the issue.
Kernel upstream commit e5d527be7e6984882306b49c067f1fec18920735 seems to be the cause here. This made it into 6.17.8 and 6.18RC5
Are there any plans to backport the fix to version 6.17.x kernel?
Want to give https://koji.fedoraproject.org/koji/taskinfo?taskID=139342035 a try and see if that works for you?
(In reply to Justin M. Forbes from comment #9) > Want to give https://koji.fedoraproject.org/koji/taskinfo?taskID=139342035 a > try and see if that works for you? This worked. Installed, rebooted on the 6.17.9 build from the link provided and audio is back to working again. Thank you, kindly.

(In reply to Michael Cronenworth from comment #11) > This does not work for my Lenovo Yoga 9i Aura. Had to downgrade again. Sorry, Justin. I saw the package name was the same as the F43 update and incorrectly assumed it was the same. Your scratch build *does* fix audio for my Lenovo. Thank you.
This is the commit that was reverted in Justin's scratch build. I would not have guessed it was the cause. https://github.com/torvalds/linux/commit/25decf0469d4c91d90aa2e28d996aed276bfc622
Fixed with the Fedora 6.17.10 update. Thanks.
Speakers does work with 6.7.10 but the headphone jack while getting detected does not output anything with 6.7.10. Both works with 6.7.7. Is this the case for others?

Sorry, there was a typo in my comment I meant kernel 6.17.x. Headphone jack output do not work in 6.17.10. My laptop is Yoga 9 2-in-1 14ILL10 and uses Lunar lake.
Still not working in 6.17.10 unfortunately. headphone jack output does not work, Dell Pro Max 16
Fortunately, USB-C earphones are working fine. but hopefully this bug will be fixed.
Still not working in 6.17.12-300.fc43.x86_64. headphone jack output does not work, Dell Pro Max 16
Issue is still present in kernel-6.18.3-100.fc42.x86_64, Yoga Slim 7 14ILL10
(In reply to Mihai Harpau from comment #22) > Issue is still present in kernel-6.18.3-100.fc42.x86_64, Yoga Slim 7 14ILL10 Came here to report the same on kernel-6.18.3-200.fc43. This was fine from 6.17.10 to 6.17.12 (F43 did not get 6.17.13), but has returned with 6.18.3.
Thanks for the update. I reverted the patch in 6.17 but assumed that the additional fixes required would have made it to 6.18. Let me see what's going on. I can certainly do a revert again, but that just puts off the problem of a proper upstream fix.
Is the revert included in 6.18.4?
Great news! Issue seems to be fixed in kernel-6.18.4-100.fc42.x86_64, Yoga Slim 7 14ILL10 Lunar Lake: - sound is back as in 6.17.7 - also headphone jack output is working again
(In reply to traxtopel from comment #25) > Is the revert included in 6.18.4? Yes, the revert is included in 6.18.4
