i am using ubuntu 18.04 Lts and i have installed PulseEffects for audio management. I use a logitech g613 keyboard. Play/pause of the media keys seems to work fine but the problem is in the volume keys. by pressing them it changes the mic volume instead of the speakers volume. And specifically when i press them it says "PulseEfects(mic)" above the volume bar in the screen. How can i change it so when i press these volume up/down buttons i change the speakers volume instead of the mic volume?
