** Description changed:
This laptop has had non-functioning internal sound (based on AMD Renoir)
until Ubuntu 24.04, which made it work thanks to a bugfix in the kernel.
Unfortunately, the sound is completely broken with kernel from package
"linux-image-6.8.0-38-generic" (6.8.0-38.38): the internal speakers are
not even listed in the sound GUI (I am using "mate-volume-control", with
Ubuntu-Mate.
When I boot the laptop on Linux 6.8.0-36-generic, the speakers are
listed and the sound works normally.
This might be related to this bug in Linux kernel:
