Maybe you have > to scroll with the right arrow key to see those channels? Ah, that was the problem. There are four effective volume controls in alsamixer: master, PCM, front, and side. They seem to multply together (each in the range 0 to 1). My "side" was only at ~30/100, the others being around 80. Now they're all set to 93/100, and the volume control on the speakers works sensibly. Why "side"? What is "PCM"? Presumably all these controls are for massive batteries of loudspeakers right, left, centre and behind. > Wonko -- Alan Mackenzie (Nuremberg, Germany).
