Hardware: Laptop: Tecno Megabook K16S AMD 7000 CPU: AMD Ryzen 7 7735HS with Radeon Graphics Audio codec: Realtek ALC269VC Subsystem ID: 0x1f5c0018 Kernel: 6.19.10-300.fc44.x86_64 Distribution: Fedora 44 KDE Plasma 6.6.4 Problem: Internal speakers produce no sound. Headphones work when connected. Bluetooth audio works. Diagnostic findings: Codec detects speakers (Node 0x14: "Speaker at Int N/A") Speaker playback volume control exists and is set to 80% However, the amplifier on pin 0x14 shows: Amp-Out vals: [0x00 0x00] (muted/zero) Manual attempts to enable amplifier with hda-verb don't produce sound EAPD is present but enabling it doesn't help What I tried: options snd-hda-intel model=auto - no effect options snd-hda-intel model=laptop - no effect options snd-hda-intel model=alc269-dmic - no effect options snd-hda-intel model=dell-headset-multi - no effect options snd-hda-intel model=hp-dv7-4000 - no effect options snd-hda-intel model=lenovo-101e - no effect options snd-hda-intel model=asus-mode1 - no effect options snd-hda-intel model=alc269-vieo - no effect options snd-hda-intel power_save=0 - no effect options snd-hda-intel dmic_detect=0 - no effect options snd-hda-intel enable_msi=1 - no effect Manual hda-verb /dev/snd/hwC1D0 0x14 SET_AMP_GAIN_MUTE 0x7f - no effect Manual hda-verb /dev/snd/hwC1D0 0x14 SET_EAPD_BTLENABLE 0x2 - no effect Tested with latest mainline kernel 6.19 - no effect Additional info: Bluetooth audio works fine HDMI audio works Headphone jack detection works (system detects when headphones are plugged in) USB audio cards work This appears to be a missing quirk for Tecno laptops with ALC269VC. The amplifier on the speaker pin needs to be properly initialized.
