Ubuntu Support Template
Ubuntu Version:
24.04.4 LTS, 26.04 Daily 2026-02-13
Desktop Environment (if applicable):
GNOME 46 and 50 beta, Wayland session.
Problem Description:
I installed Ubuntu 24.04.4 in TPM FDE mode.
The only available sound output device is the “Dummy output”.
Have no idea why, but in TPM FDE mode, the default Linux kernel for Ubuntu 24.04.4 is 6.8. I switched it to HWE/Stable 6.17, but it hasn’t resolved the issue.
I also tested the latest Ubuntu 26.04 daily build with Linux kernel 6.19 in TPM FDE mode; the issue persists.
Relevant System Information:
HP EliteBook 860 G11 16”
Intel Core Ultra 7 165H
Arc Xe-LPG 128EU graphics.
Firmware: W70 Ver. 01.08.01
