The Fix

Improving Sound Quality with EasyEffects

Tested On If you have a Samsung Galaxy Book4 Pro running Linux, you've probably noticed that the internal speakers don't work. The headphone jack works fine, but the built-in speakers are completely silent — regardless of your distro or kernel version. This post documents what actually works after hours of research through forums, repositories, and documentation. The Galaxy Book4 Pro uses the Realtek ALC298 codec combined with MAX98390 smart amplifiers connected via I2C bus. The Linux kernel detects the codec correctly, but never initializes the MAX98390 amplifier — resulting in completely silent speakers. On Windows, Samsung installs a proprietary DSP driver that automatically initializes and controls this amp. On Linux, that driver simply doesn't exist. First, confirm your hardware is affected: If you see Codec: Realtek ALC298 and a Subsystem ID starting with 0x144d (Samsung), you're in the right place. Also confirm the amp is never initialized: If there are no lines about MAX98390, the amp was never woken up. Thanks to the amazing work by @Andycodeman and the open source community, there's a DKMS driver that solves the problem. The fix installs the MAX98390 driver, creates a systemd service that initializes the amp on every boot, and works automatically after restarting. Before installing, verify: Installation (Ubuntu/Zorin/Mint/Pop!_OS): Test without rebooting: If sound comes out, reboot to confirm it persists: The driver initializes the amp, but the sound is more "raw" than on Windows (where Samsung uses proprietary DSP). To improve it, install EasyEffects: In the Effects → Output tab, add: Set EasyEffects to run in the background: ⋯ → Launch as a Service 👉 Repository: https://github.com/Andycodeman/samsung-galaxy-book-linux-fixes Templates let you quickly answer FAQs or store snippets for re-use.
