Audio issues galaxy book5 pro

[Norrox]

Im unable to get the internal speakers to fire.
No expert here but i dont think the amp is knowing how to power on.

There is an older script to get these to work on older laptops. But they dont work with these.

Is this something we can fix here or does this fix need to be somewhere else?

Thanks

Can you try

echo "options snd_hda_intel model=alc298-samsung-amp-v2-4-amps" | sudo tee /etc/modprobe.d/99-audio-fix.conf

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). See the repo README for details and workarounds.

Correction to my previous comment: The note about DMIC not working on "any of these models" was too broad. On some Galaxy Book5 models (e.g., Book5 Pro 360 on Lunar Lake), the built-in microphone may already work under the default SOF driver. However, installing the speaker fix switches to the legacy HDA driver, which will disable a working DMIC. If your internal mic currently works, be aware of this trade-off before installing the speaker fix. See the repo README for a per-model breakdown.
