Bug 396835: Feature Request: Add a "silence mode" to plasma-pa
https://bugs.kde.org/show_bug.cgi?id=396835



--- Description ---
Created attachment 114107
  --> https://bugs.kde.org/attachment.cgi?id=114107&action=edit
Very simple mockup to only explain the idea.

# Consider the following situation:

The internal speakers are not muted and no music/video/sound is playing.
You decide to listen to music or to watch a video and in order to not disturb
anyone around you, you plugin your headphones.

You may mute the sound now, but once you unplug your head phone, your internal
speakers will play loud as they were not muted before, since their mute state
was cached.

You cannot easily access the setting to mute all outputs (at once) as long as
your headphones are plugged in.
Of course you could have muted the internal speakers before the head phones are
plugged in, but there’s always the chance that you forget about doing it.

# Suggested solution: 

To workaround that, I would like to propose to introduce a “library" or
"silence mode". That could be simply a button in plasma-pa, as seen in my badly
composed mockup, which deactivates all sounds as long as it is checked. 
It could also be configurable to allow you to mute the internal speakers
automatically, when the headphones are unplugged.
