It's been eons since I heard of any kind of trouble with ncurses. :-) sbox I'm not familiar with. :-( I have a Dell gfxcard on a Buster test box that may be the same as yours except for the brand. Perhaps you'd see improvement by swapping the radeon DDX for the default DDX (modesetting) as I use here. I don't usually try to make sound work, or even connect speakers, on my test boxes, but alsamixer does open seemingly ready to take orders: http://fm.no-ip.com/SS/Deb/alsamixer10m.png Simplest way for you to switch DDX should be to purge xserver-xorg-video-radeon. -- Evolution as taught in public schools is religion, not science.
