Is it only me, or have other plasma-desktop users noticed that the audio has recently disappeared from your desktop? It just now happened for the third time in 2 days on my desktop, and I also saw it on my KDE laptop today. It is restored with a reboot, but I haven't looked deeper to find out when and how it disappears. Thanks for any ideas -- I assume a recent update introduced some instability related to this.
disappearing audio means the kmixer speaker icon disappears ?
I have the same issue since a week or two - by starting kmixer from the multimedia menu, the icon come back....

The volume icon remains on the panel, but it is gray and if you click it, it says "no device found". Next time it happens, I will try restarting kmixer from systemsettings.
