Title:
Upgrade from 16.04 LTS to 18.04 LTS breaks sound due to missing
package dependencies
Status in linux package in Ubuntu:
Incomplete
Bug description:
I upgraded one of my desktops from Xubuntu 16.04 LTS to 18.04 LTS.
This broke alsa/pulseaudio, because the upgrade failed to install the
linux-modules-extra-* package.
Before the upgrade, sound worked fine, after the upgrade pulseaudio
only showed the infamous "Dummy device".
Installing, in my case, linux-modules-extra-4.15.0-30-generic and
rebooting fixed the problem.
While i, generally, understand that you might want to minimize the
amount of kernel modules (which is why this is an extra package, i
presume), when the system has alsa and pulseaudio installed, it makes
sense to also install the relevant kernel drivers.
If you don't want to install the "extra" modules in all cases, please
make alsa and/or pulseaudio depend on them. Not doing so breaks sound
on a lot of devices, because the "extra" module also includes the
driver for many Intel onboard sound devices.
