Allow setting the volume to more than 100%

[donadigo]

It's sometimes useful in loud environments to set the volume to more than 100% so that you can still hear the sound pretty well. I think that we should make up some fixed limit like 130% so that the sound doesn't get distorted or anything.

I always see this as a reported issue, usually for laptops with extra quiet speakers. Isn't this a hardware/firmware concern?

I almost always use headphones so can't speak for laptop speakers. I would say that the volume of my speakers is loud enough, and I wouldn't expect them to be louder, but the case I'm thinking about here is when the source audio is too quiet or either the environment too loud.

I reported this issue because recently I was watching a stream and the stream volume was okay, but the environment was too loud to hear the stream audio comfortably. I opened settings to see if the volume slider allowed that and it doesn't, so I did a command in terminal to actually make the audio louder. That did the trick.

I wonder if we implement this if it should be as a separate "Gain" control since distortion might be introduced

At the moment my workaround is to set…
gsettings set io.elementary.desktop.wingpanel.sound max-volume 130
So i easily can higher the volume with my mouse-wheel at wingpanel-indicator-sound.

I can confirm the workaround works on elementary Hera (logout/login or reboot may be needed)
