** Description changed: Regression on Ubuntu 24.04 HWE kernels (Linux Mint 22.2). Hardware: - Intel CometLake-S GT2 UHD Graphics 630 (8086:9bc8), i915 - HDMI-1 to Sony TV, 1920x1080 - Analog Aux is unaffected Last good: 7.0.0-31-generic First bad: 7.0.0-34-generic Still bad: 7.0.0-38-generic On 34 and 38, HDMI video freezes about 5 seconds at start, then voice is about 2 seconds late. Firefox, Brave, and Celluloid all show it. Aux stays in sync. PipeWire latency offset does not change it. 7.0.0-31 is clean with the same Xorg (2:21.1.12-1ubuntu1.8), so this is not the Xorg update from 2026-09-29. - ubuntu-bug linux refused the report: "This does not seem to be an - official Linux package" on linux-image-7.0.0-38-generic (Mint). + ubuntu-bug linux refused the report: "This does not seem to be an official Linux package" on linux-image-7.0.0-38-generic (Mint). + --- + ProblemType: Bug + ApportVersion: 2.28.3-0ubuntu0.1 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: brett 2067 F.... pipewire + brett 2070 F.... wireplumber + /dev/snd/pcmC0D3p: brett 2067 F...m pipewire + /dev/snd/seq: brett 2067 F.... pipewire + CRDA: N/A + CasperMD5CheckMismatches: ./boot/grub/efi.img + CasperMD5CheckResult: fail + CurrentDesktop: i3 + DistroRelease: Linux Mint 22.2 + InstallationDate: Installed on 2025-12-25 (285 days ago) + InstallationMedia: Linux Mint 22.2 "Zara" - Release amd64 20250828 + MachineType: Micro-Star International Co., Ltd.
