hello, Im having a problem with volume control in solus mate that just happened in the last week or so. I use a wirelesss keyboard/touchpad from logitech. until a few days ago the volume control keys on the keyboard worked fine but now it doesnt, it still shows the icons on screen indicating the volume is going up or down but the volume does not change, I have to go in and change in manually, usually in firefox, smplayer or audacious. Any idea what caused this and how to fix it?
