linux [Meteor Lake + Realtek ALC298? Samsung NP960XGK] Internal speakers silent on SOF; HDMI audio works

On Samsung Galaxy Book4 Pro (NP960XGK) with Meteor Lake-P HD Audio Controller and Realtek codec, PipeWire exposes Speaker/HDMI sinks under SOF, microphones work, HDMI audio works, but internal speakers are silent. ALSA mixers are unmuted, Auto-Mute disabled, and trying EAPD/pin widget enable via hda-verb does not restore speaker output. Legacy HDA (with SOF disabled) is untested/partial; HDMI is used as a workaround. Regression not confirmed; persists on latest Fedora kernel as of [date].

Hardware:

Laptop: Samsung Galaxy Book4 Pro 16 (NP960XGK) [adjust if different] CPU/Platform: Intel Meteor Lake-P Audio: Meteor Lake-P HD Audio Controller + Realtek codec (likely ALC298 family) Display/audio over HDMI: working Software:

Distro: Fedora 42 Kernel: uname -a: [paste] SOF firmware/topology: sof-logger -l /lib/firmware/intel/sof/ or sof-info output [see “Data to attach”] PipeWire: 1.4.9 WirePlumber: 1.4.9 ALSA utils: 1.2.14 Observed behavior:

wpctl status shows Speaker and HDMI sinks; selecting Speaker produces no sound in any app. HDMI sink plays audio normally. ALSA controls: Auto-Mute Mode: Disabled Speaker: 100% unmuted hda-verb attempts: hda-verb /dev/snd/hwC0D0 0x17 SET_EAPD_BTLENABLE 0x02 -> value=0x0 hda-verb /dev/snd/hwC0D0 0x21 SET_EAPD_BTLENABLE 0x02 -> value=0x0 hda-verb /dev/snd/hwC0D0 0x17 SET_PIN_WIDGET_CONTROL 0x40 -> value=0x0 No audio output afterward. speaker-test plays (no errors), but no audible output from speakers. Expected behavior:

Internal “Speaker” sink should produce sound. Steps to reproduce:

Boot Fedora 42 on Samsung NP960XGK with default SOF stack. Ensure card profile: pactl set-card-profile "HiFi (HDMI1, HDMI2, HDMI3, Mic1, Mic2, Speaker)" Set default sink to Speaker and unmute: wpctl set-default <Speaker sink ID> wpctl set-mute <Speaker sink ID> 0 wpctl set-volume <Speaker sink ID> 1.0 Confirm ALSA mixers: amixer -c 0 set 'Auto-Mute Mode' Disabled amixer -c 0 set 'Speaker' 100% unmute Play test tone: speaker-test -D default -c 2 -t sine -f 440 -l 1 Observe: no sound from internal speakers; HDMI works if selected. Notes:

PipeWire previously showed only “Dummy Output” until card profile was reapplied; current kernels expose proper sinks. Looks like a SOF topology/codec-init quirk for this Samsung model—likely missing EAPD/amp enable or GPIO amp control in the topology/quirks. Willing to test patches or debug builds.

@shumingfan could this be a missing HDA verb ?

This platform also has speaker Amp. It's not own by Realtek. Please report to Samsung or Amp vendor directly.
