The system will have DSP panic while loading sof-soundwire driver on Intel LNL platform. There will be no functional audio input/output devices. [Fix] Only firmware-sof v2.13 on Noble needs to update the signed ipc4-lib binary files for the DSP FW of the Intel LNL platform. The firmware-sof on Questing are already in sync with tthe upstream version v2.13.1 which already copy the required ipc4-lib to the correct path. [Test Case] 1. Boot up the laptops powered by Intel LNL platform with sof-soundwire driver 2. Open settings->Sound->Output Device/Input Device 3. Check if there's valid input/output device instead of Dummy devices. [Where problems could occur] The ipc4-lib files are now for Intel LNL platform only and the updated v2.13 ipc4-lib is only for the updated v2.13 DSP FW. No regression expected at the current stage. ====================== original bug report ========================== [Summary] During the machine setup in the lab, I found audio test failure on 2 HP laptops. They are hp-elitebook-x-g1i. https://certification.canonical.com/hardware/202504-36592/ https://certification.canonical.com/hardware/202504-36591/ [Reproduce steps] 1. enable proposed 2. apt install firmware-sof-signed 3. reboot [failure rate] 1/1 ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: firmware-sof-signed 2023.12.1-1ubuntu1.8 ProcVersionSignature: Ubuntu 6.11.0-1027.27-oem 6.11.11 Uname: Linux 6.11.0-1027-oem x86_64 ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 CasperMD5CheckMismatches: ./casper/initrd ./casper/minimal.standard.live.hotfix.size ./casper/minimal.standard.live.size ./casper/minimal.manifest ./casper/minimal.standard.manifest ./casper/minimal.standard.size ./casper/minimal.hotfix.size ./casper/minimal.standard.live.hotfix.squashfs ./casper/minimal.standard.hotfix.squashfs ./casper/minimal.standard.hotfix.size ./casper/minimal.hotfix.squashfs ./casper/minimal.standard.live.manifest ./casper/minimal.size ./boot/grub/grub.cfg CasperMD5CheckResult: fail Date: Tue Sep 2 07:14:27 2025 Dependencies: DistributionChannelDescriptor: # This is the distribution channel descriptor for Ubuntu 24.04 for HP # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-stella-noble-oem-24.04b-20250407-101 InstallationDate: Installed on 2025-09-02 (0 days ago) InstallationMedia: Ubuntu OEM 24.04.1 LTS "Noble Numbat" - Release amd64 (20250407) PackageArchitecture: all ProcEnviron: LANG=en_US.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color SourcePackage: firmware-sof UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firmware-sof/+bug/2121849/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
