ALC298 internal speaker not working on Meteor Lake on Ubuntu 24.04.2 LTS #5483
Description
I have a system with Intel Meteor Lake-P and Realtek ALC298 codec. Sound works via HDMI and headphones, but the internal speaker (pin 0x17) is detected but never routed. Tried both SOF and legacy drivers (snd_hda_intel), no audio from speaker.

@paulstelian97, I'm afraid there is not much we can do to help with vendor specific HDA codec/amp configuration, Samsung Galaxy Books tend to have issues under Linux:
https://github.com/thesofproject/linux/issues?q=is%3Aissue%20state%3Aopen%20galaxy
You can verify that this is a codec/amp issue by following https://thesofproject.github.io/latest/getting_started/intel_debug/suggestions.html#disable-sof-on-pci-hdaudio-devices-to-test-audio-playback , a silent speaker in legacy HDA mode would confirm this.
The kernel have quirks for book1/2/3, some might make the speaker working on book4
ALC298_FIXUP_SAMSUNG_AMP_V2_2_AMPS, ALC298_FIXUP_SAMSUNG_AMP_V2_4_AMPS, but likely these newer devices will need new quirk.
Background: The HDA verbs needed for the device should be stored in BIOS by the vendor. If they are missing then the OS cannot know what commands needs to be used to configure the audio codec/amp. The vendors tends to ignore Linux and they have product specific 'hacks' in driver to make Windows working. We don't have access to these hacks to help users with Linux.
