Ubuntu – No sound notification in KDE Plasma Desktop

14.04indicator-soundkde4plasma

I installed the KDE plasma desktop yesterday on my Ubuntu 14.04 system. The environment has been working quite well up until now.

However, I just noticed that there was no Sound notification icon in the panel.

Although the sound seems to be working, it's very faint. Even after adjusting the volume from System Settings->Notifications->Player Settings and increasing it to 100% the sound remains faint.

How do I restore the notification area sound indicator and fix the volume problem?

P.S. This problem is only on the KDE environment. Sound is working just fine on GNOME.

Starting Plasma 5.4 the new plasma-pa package was introduced to replace kmix.

Remove kmix, install plasma-pa and restart plasmashell to see changes:

sudo apt-get remove kmix
sudo apt-get install plasma-pa
killall plasmashell
