Ah, that was the problem. There are four effective volume controls in |
| 22 |
alsamixer: master, PCM, front, and side. They seem to multply together |
| 23 |
(each in the range 0 to 1). My "side" was only at ~30/100, the others |
| 24 |
being around 80. |
| 25 |
|
| 26 |
Now they're all set to 93/100, and the volume control on the speakers |
| 27 |
works sensibly. |
| 28 |
|
| 29 |
Why "side"? What is "PCM"? |

|

Presumably all these controls are for massive batteries of loudspeakers |
| 32 |
right, left, centre and behind. |
