After a recent re-install of a Debian Etch machine, not only had the
master volumes been set to zero, they had been muted too.

Or using alsamixer:
If you see 'Item: Master [Off]' (top left corner) when the 'Master'
channel is selected (it should be when the program starts, otherwise
use the left/right arrow keys) press the 'm' key to unmute it.

Another indicator is at the bottom of the volume control. "MM" means
both channels are muted, "OO" means both are "On" (I guess).
