Can I boost the volume above 100% without going into System Settings?

Question

Is there a tweak that allows me to boost the volume above 100% without having to go to System Settings -> Sound every time?

Answer 1

r3bl's answer does not work on the latest version of Elementary OS

Essentially what you need to do now is:

1. Install dconf-editor
2. Run dconf-editor as YOUR user, NOT sudo / root
3. Navigate to /io/elementary/desktop/wingpanel/sound/max-volume
4. Toggle Use Defaults to False
5. Change max to number of your choice
6. Navigate to /org/gnome/desktop/sound
7. Toggle Use Defaults to False
8. Make current value True (this seems to allow the use of the keyboard shortcuts for volume)
9. Exit

Hope this helps!

Answer 2

Surprisingly, yes!

First, open up dconf-editor (if you don't have it yet, you can install it with sudo apt-get install dconf-editor).

Then, navigate through com -> ubuntu -> sound and enable the allow-amplified-volume option.

By doing so, you'll be able to increase the volume above 100% by using the Wingpanel's sound indicator. However, you still won't be be able to use the multimedia keys on your keyboard to go above 100%.
