Here's a better workaround, i.e. both speakers as well as microphone work properly (tested on a Lenovo Thinkpad X1 Carbon Gen 12 with a TPM backed FDE setup running Ubuntu 24.04.3):
apt download firmware-sof-signed dpkg-deb -x firmware-sof-signed_*.deb extracted sudo mkdir /lib/firmware/intel-extras sudo mv extracted/lib/firmware/intel/* /lib/firmware/intel-extras/ Now you just need to append 'firmware_class.path=/lib/firmware/intel- extras' to the kernel boot cmdline. Unfortunately, in these hybrid setups (snap kernel + classic ubuntu) which is the case when using TPM backed FDE, there doesn't appear to be a straightforward way to modify the kernel cmdline. grub-mkconfig breaks grub since grub is managed by snap in these setups, and the snap setting 'snap set system system.kernel.dangerous-cmdline- append="firmware_class.path=/lib/firmware/intel-extras"' only works on Ubuntu Core. So, the hacky solution is to manually edit /boot/grub/grub.cfg and add 'firmware_class.path=/lib/firmware/intel-extras' to the boot cmdline. This is not reliable since updates can overwrite grub.cfg, but the hack is relatively simple to restore should grub.cfg get updated. If anyone knows a less hacky way to modify the kernel boot cmdline in these setups, please do tell. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to firmware-sof in Ubuntu. https://bugs.launchpad.net/bugs/2092363 Title: Missing (but referenced) SOF firmware in pc-kernel – No Audio Status in canonical-kernel-snaps: Confirmed Status in pc-kernel-snap: Invalid Status in apt package in Ubuntu: Invalid Status in boot-managed-by-snapd package in Ubuntu: Invalid Status in firmware-sof package in Ubuntu: Confirmed Status in linux package in Ubuntu: Invalid Bug description: I am encountering an issue with the pc-kernel snap on my HP EliteBook 840 G11 laptop running Ubuntu 24.04.1 LTS with the new TPM+FDE feature. Despite testing multiple kernel channels, the system fails to detect any audio devices. However, when booting into a live session of Ubuntu 24.04.1 LTS, audio functions as expected. This suggests the issue may be related to the pc-kernel snap. Right now I'm on channel 24/stable (version: 6.8.0-50.51), but I have tried 24-hwe/stable and 24.10/stable as well. For reference, I have first tried to seek help in the support section over at Ubuntu Discourse, and I was encouraged to file a bug report here against the linux package on Discourse: https://discourse.ubuntu.com/t/no-audio-device-detected-on-hp-elitebook-840-14-g11-running-ubuntu-24-04/51498/7 Details: OS: Ubuntu 24.04.1 LTS Setup: TPM-backed Full Disk Encryption (FDE) using pc-kernel snap Kernel Channels Tried: 24-hwe/stable, 24/stable, 24.10/stable Issue: aplay -l reports "no sound card found"; only "Dummy output" is listed in Audio settings.
