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: prepare clock stop 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.

As a workaround, I tried to put headphones+microphone into the Jack socket on the laptop, but that seems to be completely ignored. I see no new input/output devices, there's no new message in journactl on connection, just no-op. I tried multiple headphones (TRS and TRRS), no change. The kernel problem with the sound card seem to affect the Jack socket as well. And interestingly, I can't even make headphones+mic work through Jack socket in a docking station (connected through usb-c), also no-op. Another option would be native usb-c headphones, but I don't have any, so can't test that.
Hi Kamal, Sorry took so long to get to this (still travelling - back home on Monday) I believe we need to update your FW - there are some settings missing in the version you have. I'll figure out what to get you (I was doing a scan of emails and there have been some updates whilst I was away, so want to make sure I get you the right version). Once updated I think it will fix it. Mark
