Public bug reported:
It looks like there are similar issues the lunar lake chips, but I have
a new Lenovo Lunar Lake laptop and get no sound through the internal
speakers on Ubuntu 24.04.3, kernel 6.14.
Sound *does* work through the headphone jack and when outputting via
HDMI.
The firmware-sof-signed package is installed (2023.12.1-1ubuntu1.10).
The listed output "Settings -> Sound" is "sof -soundwire". No matter
what volume output I set that to, there is no sound from the speakers.
Sound does come out of the internal speakers on the included Windows 11
installation. Sound did *not* come out of the internal speakers in a
live environment on an Ubuntu 25.10 installation (kernel 6.17).
Any help/guidance would be appreciated!
