Hardware volume keys don't work on upgrade to Xubuntu 18.04

[bmaupin]

I just upgraded to Xubuntu 18.04 from 16.04 and my hardware volume keys (mute, volume up, volume down) weren't working at all. They worked just fine on 16.04 and 14.04. I'm using a ThinkPad T430u.

Based on the suggestion here I installed xfce4-volumed and that fixed the problem right away:

Should this package be automatically installed?

$ lsb_release -rd

$ apt-cache policy xfce4-volumed

xfce4-pulseaudio-plugin is installed and used instead now.

Does adding the plugin to the panel solve your issue?

[bmaupin (bmaupin)]

I added the PulseAudio Plugin to the panel and uninstalled xfce4-volumed. But then I had 2 volume indicators. I had to hide the old one manually:

gsettings set com.canonical.indicator.sound visible false

Thanks!

The release notes inform the user about this change [1].

However, I am not sure how the upgrade process is handled. I would assume that both xfce4-volumed and indicator-sound are removed automatically (unless marked as manually installed by the user).

Adding the new plugin to the panel can only be done by the user (it is done automatically for newly created user accounts).

[bmaupin (bmaupin)]

Ah, I see. It looks like I still had indicator-sound installed.

I reset my panel to the default and it made some other changes in line with the release notes, like adding the Status Notifier Plugin and Notification Plugin. I guess I'll need to pay closer attention to the release notes next time.

Thanks!
