In trying to be independent and learn without bugging the experts here, I followed links to the YouTube tutorials. When I activated them, I found the volume to be so low that I could not hear the voice over instructions. I checked to see that the YouTube volume slider was maximized and checked the system volume slider to find it, too, maximized. My speaker volume is correct for other Internet audio sources and for music that I play.
If this is not a bug, what do I need to know to overcome this problem? The tutorials are useless to me if I cannot find a fix. Have others reported this?
