Title:
No Audio Device Detected on HP EliteBook 840 G11 with pc-kernel Snap
Status in linux package in Ubuntu:
Confirmed
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.
Observation: Audio works correctly in a live session of Ubuntu 24.04.1 LTS.
Listing audio devices:
$ aplay -l
aplay: device_list:277: no soundcards found...
