Public bug reported:
I am using Ubuntu 26.04 LTS on an Acer Swift Neo SFN14-56 with an Intel
Core Ultra 5 226V processor.
Problem:
The internal speakers do not work. ALSA detects only HDMI playback devices, and
no internal-speaker playback device is listed.
Hardware:
- Laptop: Acer SFN14-56
- Audio controller: Intel Lunar Lake-M HD Audio Controller [8086:a828]
- Kernel: 7.0.0-38-generic
- Active driver: sof-audio-pci-intel-lnl
Relevant kernel log messages:
- No SoundWire machine driver found for the ACPI-reported configuration
- part id 0x6244 is not supported
- using HDA machine driver skl_hda_dsp_generic now
The SOF firmware loads and boots successfully, but the internal audio
playback device is missing.
The module snd_soc_sn624x_sdca_sdw is not present in my installed
kernel.
Expected result:
The internal speakers should be detected and produce sound.
Actual result:
Only HDMI playback devices are listed by aplay -l, and the internal speakers do
not work.
Please investigate support for the SoundWire codec with part ID 0x6244 and the
appropriate audio machine-driver configuration for this Acer laptop.
