For anyone looking for an easy way to apply these fixes — I've packaged tested, automated install scripts for both the speaker and webcam issues on Samsung Galaxy Book4 (and others) laptops:
https://github.com/Andycodeman/samsung-galaxy-book4-linux-fixes Speaker fix: DKMS driver for the MAX98390 I2C amplifiers (based on thesofproject/linux PR #5616). Auto-rebuilds on kernel updates and auto- removes itself when native kernel support lands. curl -sL https://github.com/Andycodeman/samsung-galaxy-book4-linux- fixes/archive/refs/heads/main.tar.gz | tar xz && cd samsung-galaxy- book4-linux-fixes-main/speaker-fix && sudo ./install.sh && sudo reboot Webcam fix: Handles IVSC module loading, Intel IPU6 camera HAL setup, v4l2loopback relay, and PipeWire device classification. Works with Firefox, Chrome, Zoom, Teams, OBS, mpv, and more. curl -sL https://github.com/Andycodeman/samsung-galaxy-book4-linux- fixes/archive/refs/heads/main.tar.gz | tar xz && cd samsung-galaxy- book4-linux-fixes-main/webcam-fix && ./install.sh && sudo reboot Tested on: Samsung Galaxy Book4 Ultra, Ubuntu 24.04 LTS, kernel 6.17 (HWE). The upstream speaker PR (#5616) has also been confirmed working on the Book4 Pro, Pro 360, and Pro 16-inch by other users. If you're on a Galaxy Book5 or a different distro (Fedora, Arch, Manjaro, Debian, etc.), the fixes may still work since the underlying hardware (ALC298 + MAX98390 amps, IPU6 + OV02C10 sensor) is shared across models — but only the Ultra on Ubuntu has been directly verified. Reports from other configurations are welcome. Note: The built-in microphones (DMIC) do not work yet on any of these models — that requires SOF driver support which is expected in kernel 7.0 (April 2026) or 7.1 (June 2026).
