Bug 2483179

1. Please describe the problem:
Microphone doesn't work at all on Thinkpad X1 Carbon Gen14. There is no detected sound, even though the microphone device itself is visible, e.g. in gnome-control-center. I see the following error messages repeatedly appear in journal while trying to use the microphone:

May 29 10:42:21 chronos kernel: snd_soc_sdca_class_function snd_soc_sdca.SmartMic.0: PDE 11: power transition failed: 3
May 29 10:42:21 chronos kernel: sof_sdw sof_sdw: ASoC: POST_PMU: cs42l45 PDE 11 event failed: -110

May 29 10:42:36 chronos kernel: soundwire_intel soundwire_intel.link.3: intel_stop_bus: cannot stop clock: -110


2. What is the Version-Release number of the kernel:
kernel-7.0.10-200.fc44.x86_64

Firmware versions:
UEFI version:  N4OET47W (1.10 ) 03/30/2026
System version: N4OSG16W  (1.16)
EC version: N4OHT37W (1.07)
ME version: 21.0.2.1482

Machine type model: 21V8ZDJLUS

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 :
No

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Run gnome-control-center or any app trying to record sound, you get no input signal

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``:
Yes. Tested with kernel-7.1.0-0.rc5.260527geb3f4b7426cf.37.fc45.x86_64 .

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.
