Using Gnome’s sound volume control, I can adjust sound level from 0% to 100%.
But even at 100%, my notebook speaker output is still too soft.
Then I can use pavucontrol, to make application output to 153%, then at device output to another 153%.
However, once I use media keys or Youtube’s volume control to adjust, my adjustable range is back to 0% - 100% (only using pavucontrol again can adjust beyond 100%)
How can I change my nominal adjustable range from 0% - 100%, to 0%-153% without using pavucontrol everytime?
