In some programs it's possible to set the audio output volume above 100%. It seems to be supported by Pulseaudio up to ridiculous amounts. How can I fix this so 100% is the absolute limit?
Rationale: More than 100% is stupid, breaks sound completely (unless you have some other serious problem with your audio which you are trying to fix this way {don't do it like this}) and recently it was set too high even at boot time.
