Public bug reported: 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.
