Description

Internal speakers produce no sound on Samsung Galaxy Book 960XGL running Linux. Audio hardware is detected correctly but no sound output works. Hardware functions correctly on Windows.

Key error in dmesg

sof-audio-pci-intel-mtl 0000:00:1f.3: Topology: ABI 3:29:1 Kernel ABI 3:23:1
sof-audio-pci-intel-mtl 0000:00:1f.3: Topology file: intel/sof-ace-tplg/sof-hda-generic-2ch.tplg

Symptoms

• aplay -l shows sof-hda-dsp with device 0 (HDA Analog) correctly
• wpctl status shows Meteor Lake-P HD Audio Controller Speaker + Headphones as default sink
• Volume levels correct in alsamixer (Master/Headphone/Speaker all unmuted at 100)
• Test button in GNOME Sound Settings produces no output
• hda-verb script (TO912.sh from Manjaro forum for Galaxy Book FLEX/ION) executed without errors but no effect

Related issue

Similar ABI mismatch on kernel 6.17 reported in #10635 (Tiger Lake ALC257). This appears to be the same root cause on Meteor Lake platform.

Additional notes

• SOF firmware ABI mismatch (3:29:1 vs 3:23:1) is likely the root cause
• A newer SOF firmware compatible with kernel 6.17 or an updated topology file is needed
• Hardware works correctly on Windows
