Nothing initialises them, so the internal speakers are silent after a cold boot, while headphones, HDMI and the microphones work. A warm reboot masks the problem, as the amps stay initialised. Evidence (kernel 7.2.5-3-omarchy, sof-firmware 2025.12.2-1, PipeWire 1.6.8): - aplay -D plughw:0,0 completes with exit 0 but no audible output. - During playback the codec shows Node 0x03 Converter stream=1, Amp-Out vals [0x69 0x69] unmuted, and Pin 0x17 OUT with EAPD on — the digital path is correct, the amps simply never start. - Headphone Jack reports off, Speaker Phantom Jack reports on. - Running the known 4-amp hda-verb init sequence (amps 0x38/0x39/0x3C/0x3D, cf. joshuagrisham/galaxy-book2-pro-linux necessary-verbs.sh) restores speaker output immediately. - Machine dual-boots Windows, which explains cold-boot-only silence. This mirrors the 16Z90TR (1854:0554) case fixed with ALC298_FIXUP_SAMSUNG_AMP_V2_2_AMPS, and the 16" 16Z90R-A (1854:0489) which uses the 4-amp variant. I verified the 4-amp init works on this machine; please adjust to _2_AMPS if COEF 0x22 indicates two amps. sound/hda/codecs/realtek/alc269.c | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/hda/codecs/realtek/alc269.c b/sound/hda/codecs/realtek/alc269.c --- a/sound/hda/codecs/realtek/alc269.c +++ b/sound/hda/codecs/realtek/alc269.c @@ -8114,6 +8114,7 @@ static const struct hda_quirk alc269_fixup_tbl[] = {   SND_PCI_QUIRK(0x1854, 0x0489, "LG gram 16 (16Z90R-A)", ALC298_FIXUP_SAMSUNG_AMP_V2_4_AMPS),   SND_PCI_QUIRK(0x1854, 0x048a, "LG gram 17 (17ZD90R)", ALC298_FIXUP_SAMSUNG_AMP_V2_4_AMPS),   SND_PCI_QUIRK(0x1854, 0x0490, "LG Gram Style 14 (14Z90RS)", ALC298_FIXUP_LG_GRAM_STYLE_14), +   SND_PCI_QUIRK(0x1854, 0x053b, "LG gram 16 (16Z90SP)", ALC298_FIXUP_SAMSUNG_AMP_V2_4_AMPS),   SND_PCI_QUIRK(0x1854, 0x0554, "LG gram 16 (16Z90TR)", ALC298_FIXUP_SAMSUNG_AMP_V2_2_AMPS), Hardware: LG 16Z90SP-A.AD7BG, Intel Meteor Lake-P HD Audio [8086:7e28], Realtek ALC298 [10ec:0298] rev 0x100103, SSID 1854:053b.
