These packages have been kept back through many recent d-u. Since I had a few sound issues in the past, I am a bit nervous about getting rid of them.I checked with htop if phonon was running and there is no pid related to it while, on the other hand, pulseaudio is running.
I use regularly, firefox (youtube), vlc, kdenlive.
# apt full-upgrade -d
