Public bug reported:
After update from 22.04 to 24.04.01 my audio stopped working. The output
device is 'Dummy Output', the microphone is simply not recognised.
The problem seems to be that, by default, the old OEM Kernel from 5.X
series is used (linux-image-5.14.0-1051-oem). Once I load the new
automatically shipped one from GRUB (linux-image-6.8.0-41-generic) the
audio problems are gone.
Unfortunately lenovo.archive.canonical.com, where I suppose OEM Kernels
come from, seems to be behind, as I started getting errors for this repo
after updating too (doesn't have the component 'sutton.simon').
