Hi all. I'm on Mint Linux. I want to 100% prevent YouTube (Firefox) from touching my volume sliders. If I use pulseaudio to set Firefox playback to, for example, 153%, I don't want YouTube (Firefox) to be able to change this - EVER. Can someone tell me how to block YouTube (Firefox) access to my volume sliders? If possible, please keep the solution simple; assume I'm a total computer noob. :)
